SRAM eTap AXS Hydraulic Brake Systems

We recommend that you have your SRAM eTap AXS 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, the braking system (e.g. the brake-shift lever, caliper, and hose) will need to be replaced.

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 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 caliper. Consult the eTap AXS HRD 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 it 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.

When using a crowfoot socket and torque wrench, install the crowfoot socket at 90 degrees to the torque wrench.

Troubleshooting

Disc Brake Pad Advancement Procedure

If your brakes have excessive brake lever throw, it may be a result of the pistons sticking in the caliper. Before bleeding the system, you can try to loosen the sticky piston by performing the following steps:

Clamp the bicycle into a bicycle work stand and remove the wheel according to the wheel manufacturer's instructions.

Remove the brake pads and install the pad spreader.

Squeeze the brake lever several times until both pistons have advanced and contact the pad spreader. One piston may move faster than the other; continue to squeeze the lever until the second piston touches the spreader.

Disc Brake Pad Advancement Procedure

Remove the pad spreader.

Use a plastic tire lever to push the pistons back into the caliper bores. Repeat steps 3-5 until both pistons contact the spreader at nearly the

same time.

Reinstall the brake pads and install the wheel according to the manufacturer's instructions.

Tire lever

Disc Brake Pad Advancement Procedure

Loosen the caliper bolts.

Squeeze the brake lever several times to position the brake pads to the proper distance from the rotor.

Center the caliper on the rotor, and tighten.

Spin the wheel and check the brake function. The pistons should move freely and there should not be excessive brake lever throw.

If there is no improvement in the brake function, proceed to

Caliper Service.
