SRAM Guide RS Lever Internals Kit - 2nd Generation

What does the SRAM Guide RS Lever Internals Kit fix on your brake? The SRAM Guide RS Lever Internals Kit is the correct service kit for 2nd generation Guide RS hydraulic brake levers, containing the internal components needed to restore lever feel, eliminate sponginess, and address common wear issues without replacing the entire lever assembly. Over time, seals inside the lever body degrade from heat, contamination, and normal cycling, causing inconsistent lever travel, reduced modulation, and brake fade that bleeding alone cannot resolve. This kit addresses the root cause by replacing the worn internals with fresh OEM-spec parts, restoring the firm, progressive feel the Guide RS was designed to deliver. Brake lever internals are a service item that gets overlooked until the brake stops performing, at which point many riders assume the lever is done. In most cases, a lever internals rebuild is all that is needed to return a well-maintained SRAM hydraulic brake to like-new performance. This kit is specific to 2nd generation Guide RS levers, so verify your generation before ordering.
