SRAM G2 Brake Systems Service
S R A M G 2 B r a k e S y s t e m s S e r v i c e
We recommend that you have your SRAM G2 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.

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 brake fluid. If SRAM brake fluid is not available, only use DOT 5.1 or 4 brake fluid.
Use only DOT compatible grease.
Always wear safety glasses and nitrile gloves when working with DOT brake fluid.
Used DOT brake fluid should be recycled or disposed of in accordance to local and federal regulations.
Never pour DOT brake 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
.
⚠
CAUTION
Do not use mineral oil or DOT 5 fluid. Do not use tools, rags, or syringes that are contaminated with mineral oil or DOT 5 fluid. Using contaminated
materials will result in permanent damage to the seals and reduce braking performance. Brakes must be replaced if contaminated with mineral oil
or DOT 5 fluid.
NOTICE
The G2 caliper must be serviced before the lever. The lever must be connected to the caliper and the brakes must still have fluid in them in order to
advance the pistons and service the caliper. Once the lever has been disconnected and the fluid drained it is not possible to advance the pistons.
