Page 5: Sram Guide Brake Systems 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. -
Page 6: Service Procedures
S e r v i c e P r o c e d u r e s 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. -
Page 7: Troubleshooting
T r o u b l e s h o o t i n g N OT ICE Do not apply DOT brake fluid or grease to caliper pistons when performing troubleshooting procedures. Use of DOT brake fluid or grease can diminish braking performance and cause rotor rubbing. -

C a l i p e r P i s t o n R e m o v a l N OT ICE DOT brake fluid will damage painted surfaces. If any fluid comes in contact with a painted surface (i.e. your frame) or printing on the brakes, wipe it off immediately and clean it with isopropyl alcohol or water. - Page 11 Remove the Guide pad spreader. 2.5 mm hex wrench Use a 2.5 mm hex wrench to remove the pad retention bolt. Use a T25 TORX wrench to remove each caliper body bolt. T25 TORX wrench Separate the caliper body halves. Set the heat shield aside.
- Page 12 Remove the pistons from each caliper body half. Use a pick to remove the piston seals from each caliper body half. Install new seals inside each caliper body half. ⚠ WARNI NG 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.

NOTI CE For the best braking performance, use only SRAM High-Performance 5.1 DOT brake fluid. If SRAM fluid is not available, use only DOT 5.1 or 4 brake fluid. Do not use grease. Grease will prevent the pistons from fully retracting into the caliper bores which will reduce braking performance. - Page 14 9.8-11.8 N·m (87-104 in-lb). T25 TORX bit 9.8-11.8 N·m (87-104 in-lb) Remove the o-rings from the banjo bolt and banjo fitting. Apply a small amount of SRAM High-Performance 5.1 DOT brake fluid to the new o-rings and install them. Caliper Piston Installation...

Install new seals and a new hose. For best results, use only SRAM High-Performance DOT 5.1 brake fluid. If SRAM fluid is not available, only use DOT 5.1 or 4 brake fluid. Lever Blade Removal... - Page 18 Use a T10 TORX wrench to remove the reservoir cap bolt nearest to the lever blade. T10 TORX wrench Carefully turn the lever body upside down so that the detent spring and ball fall out of the lever body. If they do not initially fall out, gently tap the lever against a clean rag.
- Page 19 Pour the fluid from the brake lever body into a pan. Separate the bladder from the reservoir cover. Spray isopropyl alcohol on the bladder and the reservoir cover and clean them with a rag. NOTI CE All components must be completely dry before reinstalling them. Moisture residue from cleaning the bladder can leak out of the bladder as it dries, which can be misinterpreted as a system leak.

Page 23: Piston Assembly Installation
Damage to painted and/or printed surfaces by DOT brake fluid is not covered under warranty. Submerge the new piston assembly in SRAM High-Performance DOT 5.1 brake fluid. You can also use SRAM DOT Assembly Grease, or DOT 5.1 or 4 compatible grease, as a lubricant. SRAM High-Performance DOT 5.1 brake fluid Install the new lubricated piston assembly into the lever body. - Page 24 Engage the slots on the sleeve with the contact adjust knob and continue to thread the SRAM Lever Internals Assembly Tool tool in a clockwise rotation until it stops. Lever Internals Assembly Tool 20 mm or 15 mm Thru Axle Use needle nose pliers to install the SwingLink bushings.
- Page 25 The push rod length must be set to exactly 26.3 mm. Any other length will reduce brake performance. Digital Caliper Use a 2 mm hex wrench to remove the SwingLink from the SRAM Lever Internals Assembly Tool and place the pushrod into the coupler sleeve. 2 mm hex wrench...
- Page 26 Apply a small amount of Loctite Threadlocker Blue 242 onto the pinch T8 TORX wrench bolt. Use a T8 TORX wrench to thread the SwingLink pinch bolt into the lever body. Use a torque wrench and a T8 TORX bit socket to torque the bolt to 1.1-1.3 N·m (10-12 in-lb).
