Frequently Asked Questions

What's included in the kit?

Seals, cups, springs, and internal components needed to rebuild a 1/2 inch master cylinder to OEM specifications.

Do I need special tools to install this?

Master cylinder rebuild requires a rebuild kit tool or snap-ring pliers. An internal spring compressor is helpful for reassembly.

Will this fix a leaking master cylinder?

Yes — if leaking is caused by worn seals or cups, this kit restores the seal. If the bore is pitted or damaged, a new master cylinder may be required.

Is this the correct kit for my Harley or Indian?

This fits 1/2 inch bore master cylinders. Verify your bike's master cylinder bore size before ordering — larger models may use 5/8 inch or 3/4 inch bores.
