Frequently Asked Questions

Does this kit fit both stock and aftermarket master cylinders?

Yes — this rebuild kit works with OEM and aftermarket front master cylinders in the 5/8" bore size.

What's included in the rebuild kit?

Complete seal set and internal components needed to restore full hydraulic function to your front master cylinder.

Will this solve a soft or spongy brake lever?

If the sponginess is caused by worn seals or internal corrosion, this rebuild kit will restore firm brake feel. If the problem is air in the lines, you'll need to bleed the system after installation.

Is installation difficult?

Master cylinder rebuilds require disassembly and cleaning. If you're not comfortable, have a shop perform the service.
