5SRAM® Code™ Brake Systems Service
SRAM®Code™Brake Systems Service
We recommend that you have your SRAM Code components serviced by a qualified bicycle mechanic. Servicing SRAM components requires knowledge
of bicycle mechanics as well as the special tools and lubricants/fluids used for service.
SRAM brake systems need to be serviced periodically to optimize braking function. If brake fluid is leaking from any area of the brake there may be
damage or wear and tear to the internal moving parts. If the system has been contaminated with the wrong fluid there may be damage to all rubber
and plastic internal parts. If your brake was damaged in a crash there may be damage to the lever blade, pushrod, and housing assemblies. Inspect and
replace these parts to restore proper brake function.
Visit www.sram.com/service for the latest SRAM Spare Parts catalog and technical information. For order information, please contact your local SRAM
distributor or dealer.
For recycling and environmental compliance information, please visit www.sram.com.
Information contained in this publication is subject to change at any time without prior notice. Your product's appearance may differ from the pictures
contained in this publication.
SAFETY INSTRUCTIONS
Do not use mineral oil or DOT 5 fluid.
If the brake system has been contaminated with mineral oil or DOT 5 fluid, flush all of the parts with soapy water, rinse them with clean water, then allow all
the parts to dry prior to rebuilding. Install new seals, a new bladder, and replace the hose.
For best results, use only SRAM High-Performance DOT 5.1 fluid. If SRAM brake fluid is not available, only use DOT 5.1 or 4 fluid.
Use only DOT compatible grease.
Always wear safety glasses and nitrile gloves when working with DOT fluid.
Used 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 allow any brake fluid to come in contact with the brake pads. If this occurs, the pads are contaminated and must be replaced.
Place an oil pan on the floor underneath the area where you will be working on the brake.
Servicing your brakes removes all of the brake fluid from the system. You must bleed your brakes after you service the brake system. Consult the SRAM
MTB Disc Brake Hose Shortening and Bleed Manual at www.sram.com/service.
NOTICE
Before beginning service, thoroughly clean the exterior of the product to avoid contamination of internal sealing part surfaces.
DOT fluids will damage painted surfaces. If any fluid comes in contact with a painted surface (e.g. your frame) or printing on the brakes, wipe if off
immediately and clean it with isopropyl alcohol or water. Damage to painted and/or printed surfaces by DOT fluid is not covered under warranty.

6Service Procedures
Service Procedures
The following procedures should be performed throughout service, unless otherwise specified.
Clean the part with isopropyl alcohol and a clean, lint-free rag.
Clean the sealing surface on the part and inspect it for scratches.
Replace the o-ring or seal with a new one from the service kit.
Use your fingers, a ziptie, or a pick to pierce and remove the old seal or o-ring.
Apply DOT grease to the new seal or o-ring when instructed.
NOTICE
Do not scratch any sealing surfaces when servicing the product. Scratches can
cause leaks. Consult the spare parts catalog to replace the damaged part.
Use aluminum soft jaws when placing a part in a bench vise.
Tighten the part with a torque wrench to the torque value listed in the red bar.
When using a crowfoot socket and torque wrench, install the crowfoot socket
at 90 degrees to the torque wrench.
Specified torque value in N·m (in-lb)

Remove the pistons from each caliper body half.
Remove the piston seals from each caliper body half, then clean the
caliper halves. Apply a small amount of SRAM®High-Performance DOT
5.1 fluid to new seals and install into each caliper body half.
⚠CAUTION
Do not scratch the seal gland with the pick. Scratches could cause fluid
to leak when the brake is applied, which will contaminate the brake
pads and could lead to a brake failure.
NOTICE
For the best braking performance, use only SRAM High-Performance
DOT 5.1 fluid. If SRAM fluid is not available, use only DOT 5.1 or 4 fluid.
Do not use grease. Grease will prevent the pistons from fully retracting
into the caliper bores, which will reduce braking performance.
