Sticky or slow brake pad return feel

Beore completely disassembling your caliper, its worth trying to loosen the sticky piston. Try the ollowing:

1. Clamp the bicycle in a bicycle work stand.

2. Spin the aected wheel. Lightly squeeze the brake lever and watch the brake pads when the lever is released.

3. Determine which side o the caliper has a slow returning brake piston.

4. Remove the caliper rom the bicycle. I you have a caliper mounting bracket, remove the bracket with the caliper attached.

5. Remove e-clip rom the guide pin groove on top o the caliper. Use a 2.5 mm hex to remove the guide pin rom the caliper.

6. Remove both brake pads and h-spring.

7. Use a 10 mm box wrench to press the working piston into caliper body.

8. While continuing to hold the piston inside the caliper body, squeeze the brake lever slowly to move the sticky piston inward.Press the piston back into the caliper again.

9. Repeat these steps to correct caliper piston inner o-ring position.

10. Both pistons should now be moving reely. Re-install the spring pad clip, h-spring, and pads into the caliper. I there is noimprovement, continue with caliper service.

11. Re-install the caliper (or mounting bracket with attached caliper) on the bicycle. You may need to re-center the caliper to therotor. I you removed the caliper without an adapter, or removed it rom the adapter, it will need to be re-centered. Spin thewheel and check brake unction.



1Use a 5 mm hex to remove the brake caliper rom the ork orrame and remove the caliper mounting bracket and hardwarerom the caliper. Set aside in the correct order (not pictured).

2Remove the e-clip rom the guide pin groove on top o thecaliper. Use a 2.5 mm hex to remove the guide pin rom thecaliper.

3Pull and remove both brake pads and h-spring.

If the total thickness of the backing plate and pad frictionmaterial is less than 3 mm, the brake pads need to be replaced.

5Separate the caliper body halves and open the caliperassembly. Remove the banjo rom the caliper.

6Caliper Piston Removal:

Insert an air compressor chuck nozzle into thehole o one o the caliper body halves.

Cover the pistons with at least two rags. Point

the caliper pistons and rags into your hand.

Squeeze the air chuck and orce air into the hole in thecaliper hal. The compressed air will unseat the pistonsrom the caliper. Remove the pistons rom the caliper.

W A R N I N G :

Point the caliper in a sae direction. Use two rags toprevent the pistons rom causing injury or becoming lost.Repeat this process or the other caliper body hal.

If both pistons do not unseat simultaneously, coverthe open piston bore with a piece of inner tube anduse the air chuck to unseat the second piston.

7Remove the square-edge o-rings rom inside each caliper bodyhal with a sharp pick. Lubricate the new square-edge o-ringswith Avid High-Perormance 5.1 DOT Fluid and install theminside each caliper body hal.

Do not scratch the o-ring gland with the pick.You can also use Avid DOT Grease, or DOT 5.1or 4 compatible grease, as a lubricant.

Insert chuck nozzle



8Inspect the caliper pistons or damage and replace inecessary. Re-install the caliper brake pistons into each hal othe caliper body.

9Use a sharp pick to remove the o-ring on the inside eachcaliper hal. Lubricate the new o-rings with Avid DOT Greaseand install them inside each caliper body hal.

Do not scratch the o-ring gland with the pick.You can also use DOT 5.1 or 4 compatible grease as a lubricant.Make sure the o-ring is seated in the recessed gland.

10

Re-assemble the caliper halves. Loosely thread the caliper

body bolts clockwise by hand. Re-install the banjo betweenthe caliper halves.

11Use a torque wrench with a 5 mm hex bit socket to tighten thecaliper body bolts to 8.5-10 Nm (75-90 in-lb).

5 mm 8.5-10 Nm (75-90 in-lb)



12Insert the Bleed Block into the caliper in place o the brakepads.

You will need to bleed your brakes before re-installingthe brake pads.

13Clean the assembled caliper with alcohol and a clean rag toremove any brake luid.

14Visually check your work. Inspect the banjo or any protruding o-rings. I there are any o-rings that are squeezed beyond theoutside edges o the banjo or bolt, remove and replace the o-rings, and then repeat the installation process.

Overhauling the caliper introduces a small amount of air into the system, so at this point it is necessary to bleed the brakes foroptimal performance. See the section, Avid Brake Bleed Procedure for instructions.

1Make sure the hoses are properly secured to the bicycle andcheck the routing o each hose. Account or suspensionmovement and be sure the handlebars can move reely byturning the bars all the way rom side to side.

2Pull the hose boot away rom the lever to access thecompression nut. I the boot sticks, careully pry up a cornerwith something that wont harm it (like the end o a zip tie)and spray isopropyl alcohol between the boot and the lever.Work the alcohol in; the boot should loosen up and slide easilydown the hose.

3 For models with a compression nut and a hex hose stop: Usean 11 mm open end wrench to hold the hose stop in place anduse an 8 mm lare nut wrench to unthread the compressionnut.

For models with a compression nut only: Use an 8 mmlare nut wrench to unthread the compression nut.

4Pull the hose rom the lever. Be careul, DOT luid will drip romthe hose. Try not to spill too much luid because any luid thatdrips out will create bubbles that youll have to eliminate later.

Slide the nut down the hose and away romthe end where youll be cutting. Do not pull thebrake lever while the hose is removed.

5Determine where you need to cut the hose by holding it up tothe lever in the position you like. Make sure to leave a gentlebend in the hose with enough length to reely turn the bars allthe way rom side to side. Double-check this measurementbecause you cant go back ater you cut.

The groove in the lever nose marks the spot whereyoull cut the hose. Cut the hose using hydraulic hosecutters or very sharp cable housing cutters.

6Apply Avid DOT Grease to the threads o a new hose barb, thecompression itting outer suraces and compression nutthreads.

While holding the hose irmly, use a T10 TORX to threadthe hose barb into the end o the hose until it is lush.

Slide a new compression itting over the endo the hose with the new hose barb.

7

Push the hose irmly into the lever until it stops.

While holding the hose in place, slide the compressionitting and compression nut up to the lever or hose stop.

Measure twice, cut once!



8For models with a compression nut and a hex hose stop:While continuing to push the hose into the hose stop, use an11 mm open end wrench to hold the hose stop in place and usean 8 mm lare nut wrench to tighten the compression nut tothe proper torque.

For models with a compression nut only: While continuingto push the hose into the lever body, use an 8 mm lare nutwrench to tighten the compression nut to the proper torque.

I your compression itting is alloy, tighten to 5 Nm (47 in-lb).

I your compression itting is steel, tighten to 7.8 Nm (70 in-lb)

9Slide the boot back into place.

Cutting the hose introduces a small amount of air into the system, so at this point it is necessary to bleed the brakes for optimalperformance. See the next section, Avid Brake Bleed Procedure for instructions.


34/424 avid brake bleed proCedure

A V I D B R A K E B L E E D P R O C E D U R E

Avid brakes are the most powerul and precise hydraulic brakes on the market. A key reason behind this is the ability to optimizebrake perormance with a perect bleed. The goal o bleeding is to remove any air that is trapped in the hose, caliper, or lever. Airtrapped in a hydraulic brake system degrades the perormance o the brake. The ollowing instructions will walk you through oursimple bleed procedure.

Avid brakes come with hoses attached and bled. If you dont need to change the hose length, you do not need to bleed thesystem prior to installation.

When bleeding Avid brakes, keep in mind that you are simply forcing air bubbles out of the system. We recommend that youbleed your brakes at least once a year to ensure optimal performance. If you ride frequently or in aggressive terrain, you shouldbleed your brakes more often.

When bleeding brakes, you may notice discoloration of the old fluid as it exits the system into the syringe at the lever. If thefluid is severely discolored, this indicates that the fluid is very old. In this case, bleeding the system twice in order to completelyremove the old fluid is recommended.

1Fill one syringe 1/2 ull with Avid High-Perormance 5.1 DOTFluid and ill the other syringe 1/4 ull.

Hold each syringe with the tip pointed up and tapthe side o the syringe with your inger to bringany air bubbles to the top. Place a clean rag aroundthe tip and slowly push the air bubbles out o thesyringe. Close the hose clamp on each syringe.

2De-gas the luid in the 1/2 ull syringe. Leave the hose clampshut and pull on the plunger. Bubbles will orm in the brake luid. While theplunger is still pulled down, lightly tap the syringe to releasethe bubbles sticking to the sides and the bottom so that they can rise to the topo the luid. When the bubbles stop orming and have all risen to the top, release

the plunger, open the clamp and careully push the air out. Repeat several times.

You will not be able to remove all the bubbles.

3Remove the wheel rom your bike. Remove the brake pads and spreader clip romthe caliper and insert the appropriate Bleed Block. This will help prevent systemoverill and keep DOT luid rom contaminating your brakepads.

4Use the T10 TORX to remove the caliper bleed port screwrom the caliper body or banjo bolt

5Make sure the luid in the 1/2 ull syringe is pushed all the wayto the tip (no air gap!), then thread into the caliper bleed port.



6For models with Contact Point Adjustment and a rotatingbleed port screw located on the contact point adjuster:rotate the adjuster in the direction opposite the arrow untilit stops, then rotate the adjuster back just enough to placethe bleed screw at its highest point.

For models with Contact Point Adjustment and a fixedbleed port screw: rotate the adjuster in the directionopposite the arrow on the adjuster knob until it stops.

7For models equipped with Reach Adjust, make sure the tipo the lever blade is 75-80 mm rom the centerline o thehandlebar. I the lever is too ar out, it can make bleedingthe brake impossible.

8Use the T10 TORX to remove the lever bleed port screw.

9Make sure the luid in the 1/4 ull syringe is pushed all the wayto the tip (no air gap!), then thread into the lever bleed port.

It is not necessary to reposition the angle of the brake lever on

the handlebar. You may have a small amount of DOT fluid drip

from the bleed port screw, this is normal. Just have a clean rag

handy to wipe off any excess after the syringe is installed.

75-80 mm



10Hold both syringes upright.

Gently push on the caliper syringe plunger to moveluid rom the caliper syringe into the lever syringeuntil the lever syringe is increased to 1/2 ull and

the caliper syringe is decreased to 1/4 ull.

You should see bubbles form in the lever syringe.

11Close the syringe clamp on the lever.

12Pull the brake lever all the way to the bar with your inger andhold it there until instructed to release the lever in a later step.

I you dont want to hold the lever with your inger, have a riendhold it or you can asten it with a zip-tie or rubber band.

13Pull out on the caliper syringe plunger to create a vacuum thengently push in on the plunger to pressurize the system. Repeatthis procedure several times, until large bubbles stop coming out othe caliper.

Do not pull the plunger past the end of the syringe.



14Once the large bubbles at the caliper have stopped, apply asmall amount o pressure on the syringe plunger and slowly letthe pressure extend the brake lever you have been holdingwith your inger. I you astened the lever with a zip-tie orrubber bands, remove these irst but keep the lever pulled inwith your inger, then apply pressure on the syringe plunger.

You will feel the pressure at your finger on the lever, just let

the fluid extend the lever back to its original position.

15Close the clamp on the caliper syringe, then remove thesyringe rom the caliper and re-install the bleed port screw.

Use a clean rag to wipe off any excess DOT fluid that spills

out as you re-install the bleed port screw.

16Open the syringe clamp on the lever.

17Pull out on the lever syringe plunger to create a vacuum, thengently push in on plunger to pressurize the system. Squeezeand release the brake lever ten times, allowing the lever to snap backto its starting position ater squeezing (this helps break loose the bubbles).Repeat this procedure o creating a vacuum at the syringe andsqueezing the brake lever ten times until large bubbles stopcoming out o the lever.

Do not pull out too hard on the plunger or you will suck air past the plunger

seal into the fluid and create more bubbles that you will have to eliminate.



18Once the large bubbles at the lever have stopped, apply asmall amount o pressure on the syringe plunger then removethe syringe and re-install the bleed port screw.

There will be a small amount of excess DOT fluid

that spills out as you remove the syringe and re-install the bleed port screw,

this is normal. be sure to wipe the fluid off the lever with a clean rag.

19Spray isopropyl alcohol or water onto a clean rag and wipe othe brake lever and caliper to remove any excess DOT luid.

20Visually check your work. Inspect the banjo bolt and banjo orany protruding o-rings. I there are any o-rings that are

squeezed beyond the outside edges o the banjo or bolt,remove and replace the o-rings, and then repeat theinstallation process.

21Remove the Bleed Block rom the caliper and re-install thebrake pads and spreader clip.

22Reinstall your wheel according to the manuacturersinstructions.

W A R N I N G :

Empty the syringes into a sealed container and dispose of the fluid properly. Remember, DOT fluid should be recycled or

disposed of in accordance to local and federal regulations.

NEVER pour DOT fluid down a sewage or drainage system or into the ground or a body of water.

Do not re-use this fluid.

Do not leave the hose clamps closed, this will damage the clear tubing on the syringes.

23You are almost ready to ride, but irst its a good idea to testyour brakes. Pull on the lever extremely hard (as hard as youcan imagine yoursel pulling the lever while youre riding)several times. Make sure to look around the compression nuton the lever, and the banjo bolt on the caliper or any leaks.Make one last check o all the bolts and ittings.I everythingchecks out, YOU ARE READY TO RIDE!

1Remove pad retainer bolt.

Start by removing the e-clip on the wheel side o the caliper,then unthread the retainer bolt using a 2.5 mm hex.Remove the retainer bolt all the way.

2Push the pistons back in.

Elixir calipers are sel-adjusting, the pistons need to be pushedback into the body to their original position beore the newpads can be installed. The saest way to do this is with the oldpads still in the caliper to protect the pistons. Place a lat-blade screwdriver between the old pads, then careully rockit back and orth, pushing the pistons back into their bores.

3 Remove the old pads.

Grab the pad tabs and pull straight out.

4Install the new pads and spreader.

Be sure the spreader clip is oriented to the pads asshown. Align the hole in the spreader clip with the holesin the pad tabs. Squeeze the pad and clip assemblytogether, then insert into the caliper as a unit. Firmlypush until the assembly is seated into place.

5Re-install the pad retainer bolt.

Replace the pad retainer bolt, tighten to torque speciications,and replace the e-clip on the wheel side o the caliper.

41/421 disC brake pad and rotor bed-in proCedure

D I S C B R A K E P A D A N D R O T O R B E D - I N P R O C E D U R E

All new brake pads and rotors should be put through a wear-in process called bed-in. The bed-in procedure, which should beperormed prior to your irst ride, ensures the most consistent and powerul braking eel along with the quietest braking in mostriding conditions. The bed-in process heats up the brake pads and rotors which deposits an even layer o brake pad material(transer layer) to the braking surace o the rotor. It this transer layer that optimizes braking perormance.

W A R N I N G :

The bed-in process requires you to perform heavy braking. You must be familiar with the power and operation of disc

brakes. Braking heavily when not familiar with the power and operation of disc brakes could cause you to lose control ofyour bicycle, which could lead to a crash and could lead to serious injury and/or death. If you are unfamiliar with the powerand operation of disc brakes, you should have the bed-in process performed by a qualified bicycle mechanic.

I MPO RTANT:

To saely achieve optimal results, remain seated onthe bike during the entire bed-in procedure.

1Accelerate the bike to a moderate speed, then irmly apply thebrakes until you are at walking speed. Repeat approximatelytwenty times.

2Accelerate the bike to a aster speed. Then very irmly applythe brakes until you are at walking speed. Repeatapproximately ten times.

I MPO RTANT:

Do not lock up the wheels at any point during the bed-in procedure.

3Allow the brakes to cool prior to any additional riding.
