Frequently Asked Questions

Q: How do I know if my master cylinder needs a rebuild?
A: Common symptoms include a lever that pulls all the way to the bar, a "spongy" feel that doesn't improve with bleeding, or visible brake fluid leaks around the lever pivot area.

Q: Is this difficult to install?
A: It requires basic mechanical skill. You will need to drain the brake system, disassemble the master cylinder, clean the bore, and install the new seals with clean brake fluid to lubricate them.

Expert Pro-Tip

Expert Pro-Tip: Before installing new seals, inspect the internal bore of your master cylinder with a flashlight. If you see deep pitting or scratches, a rebuild kit won't fix it; the cylinder body itself will be compromised and won't hold pressure. Always use clean brake fluid to lubricate the new rubber seals during assembly to prevent tearing.
