SRAM Guide RS Lever Internals Kit

The 2nd generation Guide RS levers typically feature a revised piston design compared to the original version. If you are unsure, check your lever's model year or look for the specific internal assembly markings; this kit is designed specifically for the updated internals that addressed initial reliability concerns.

Yes, a sticky or slow-returning lever is often caused by swollen seals or a worn plunger mechanism inside the master cylinder. Replacing these internal components with this kit is the standard fix to restore the smooth, snappy action of your brake lever.

You will need a set of snap-ring pliers to remove the retaining clip, along with standard hex keys to remove the lever blade. It is also highly recommended to have a SRAM bleed kit on hand, as you will need to fully bleed the brake system after installing the new internals.

No, this kit is specifically engineered for the Guide RS lever assembly. While many SRAM brake components look similar, the internal dimensions and plunger designs vary between the R, RS, RSC, and Ultimate models, so you must use the kit that matches your specific lever model.

Rebuilding the lever is a cost-effective way to extend the life of your brakes if the lever body itself is not damaged. If your lever body is cracked or the pivot point is excessively sloppy, replacing the entire assembly is the safer and more reliable option.
