SRAM Force AXS Disc Brake Caliper Piston Service Kit

No, this specific service kit is engineered exclusively for the SRAM Force AXS disc brake calipers. While some internal components may look similar across the SRAM AXS ecosystem, tolerances and seal dimensions are specific to the Force model, so you should only use this kit for its intended application.

You likely need a service if you notice uneven piston retraction, a sticky lever feel that doesn't resolve with a standard bleed, or if you see signs of hydraulic fluid leaking around the caliper pistons. If your brakes feel sluggish or inconsistent despite fresh pads and a proper bleed, the internal seals may be worn or contaminated.

No, this kit contains only the internal hard parts and seals required for the caliper overhaul. You will need to purchase SRAM DOT 5.1 hydraulic fluid separately to complete the reassembly and bleed process.

If you are comfortable with hydraulic systems and have the correct tools—including a bleed kit and torque wrench—it is a manageable task for an experienced home mechanic. However, because this involves the braking system, you must be confident in your ability to properly seat seals and perform a thorough bleed to ensure safety.

Not necessarily. A mushy lever is most often caused by air trapped in the hydraulic line, which is solved by a standard brake bleed. This kit is intended to address mechanical issues within the caliper itself, such as seized pistons or seal failure, rather than air in the system.
