MCP 650QB & 650Q Caliper Rebuild Kit

The MCP 650Q and 650QB are the most common brake calipers in quarter midget racing and like any high-cycle component, they benefit from periodic rebuilding. This is the official MCP rebuild kit for both variants, giving you everything needed to restore like-new piston action and sealing in a single, affordable package.

Rebuilding your caliper is a fraction of the cost of a full replacement. If you're chasing a soft pedal, caliper is sticking, noticing fluid weeping around the pistons, or simply doing a thorough offseason brake overhaul, this kit is the right starting point.

What's Included:

• 2 Lightened Pistons with O-Rings
• 1 Crossover O-Ring
• 2 Bleeder Screws
• 2 Brass Bleed Screw Washers

The lightened pistons are a notable detail — they're not just replacement parts, they're the same spec used in current MCP production calipers, contributing to reduced unsprung weight without sacrificing braking performance.

Important Fitment Note: This kit fits the MCP 650Q and 650QB calipers only. It is not compatible with other MCP caliper models. Double-check your caliper model number before ordering.
