SRAM Piston Service Kit

No, this specific service kit is engineered exclusively for the SRAM Red E1 hydraulic disc brake systems. It will not fit or function correctly with previous generations of SRAM Red brakes.

You should consider a service if you notice uneven pad wear, sticky pistons that don't retract fully, or a 'mushy' lever feel that persists even after a fresh bleed. These symptoms often indicate that the internal seals have degraded or the piston movement is obstructed.

This kit contains the essential components for a single caliper piston service. If you are planning to overhaul both the front and rear brakes, you will need to purchase two kits.

If you are comfortable with hydraulic brake systems and have the appropriate tools, such as a bleed kit and torque wrench, this is a manageable task. However, because it involves the hydraulic system, precision is critical; if you are unsure about the process, a professional mechanic is recommended to ensure safety.

Yes, a full brake bleed is required after installing this kit. Opening the caliper to replace the pistons and seals will introduce air into the system, which must be removed to restore proper braking pressure.
