Frequently Asked Questions

Q: How do I know if my MCP FWB caliper needs a rebuild?

A: If you notice a spongy brake pedal, fluid leaks around the piston area, or the caliper is sticking and failing to release properly, it is time to rebuild. Replacing the piston and O-ring is a cost-effective way to restore clamping force.

Q: Is this kit compatible with all MCP calipers?

A: No, this kit is specifically designed for the MCP FWB (Front Wheel Brake) caliper and features a 1.0-inch diameter piston. Please verify your caliper model before purchasing to ensure a proper fit.

Q: What tools are required for this installation?

A: You will typically need basic hand tools to remove the caliper from the spindle, a clean workspace to prevent debris from entering the brake system, and fresh brake fluid for the subsequent bleeding process.

Q: Do I need to bleed the brakes after installing this kit?

A: Yes. Anytime you open the hydraulic system to replace a piston or seal, air will enter the lines. You must perform a thorough brake bleed to ensure all air is removed and you have a firm pedal feel.

Q: Can I reuse the old O-ring if it looks okay?

A: It is highly recommended to always use the new O-ring included in this kit. O-rings take a "set" over time and lose their elasticity; reusing an old seal is the most common cause of post-rebuild leaks.
