Essential Maintenance for Your V-Twin

Regular maintenance of your brake system is crucial for safety. This rebuild kit is an excellent choice for riders tackling a DIY brake overhaul or for shops looking for quality replacement parts.

Common questions

Does this fit my Harley master cylinder?

This kit fits V-twin motorcycles with 14 mm master cylinders, including many Harley-Davidson and Indian Motorcycle models. Please check your current master cylinder's bore size before ordering.

What's included in the kit?

The kit includes the necessary seals, pistons, and springs required to rebuild the internal components of your master cylinder. It does not include the master cylinder body itself.

Will this stop a leaking master cylinder?

If the leak is due to worn internal seals, this kit is designed to resolve that. However, if the cylinder bore itself is damaged or pitted, a rebuild kit may not be sufficient, and a new master cylinder might be required.
