No, this is a rebuild kit consisting of seals, O-rings, and screws. The master cylinder housing must be reused.
Basic hand tools, including snap-ring pliers, are typically required for disassembling the internal components of the master cylinder.
Only use the brake fluid type specified in your motorcycle's owner's manual. Most modern KTM and Husqvarna systems require DOT 4 or 5.1.
If the internal bore is smooth and free of scratches, it is generally repairable. Deep grooves in the aluminum bore will prevent the new seals from holding pressure.
There is no set mileage, but it should be rebuilt if you notice leaks, loss of pressure, or if the bike has been sitting for several years with old brake fluid.
There is likely trapped air in the system. Perform a secondary brake bleed, ensuring you bleed both the master cylinder and the caliper.
Check the cylinder bore for deep scratches or pits. If the bore is damaged, the seals will not seat properly and the master cylinder housing may need replacement.
Before installation, ensure you have a compatible brake fluid (typically DOT 4 or 5.1 as specified by your manufacturer).
Compatibility check: This kit is confirmed for specific KTM Enduro/SMC, Husqvarna 701, and Gas Gas 700 models. Always verify your specific master cylinder part number against the kit MPN before beginning.
