Performance Machine Brake Rebuild Kits: Keep Your PM Brakes at Their Best

When you've invested in a set of Performance Machine brake calipers, protecting that investment over the long haul is just as important as the initial upgrade. PM's brake rebuild kits are purpose-built to match their own caliper and master cylinder designs — ensuring that when it's time to restore your braking system, every component fits and performs exactly as intended.

Performance Machine has spent over 50 years as one of the motorcycle industry's premier manufacturers of brake systems, wheels, and controls — with a reputation built on quality, innovation, and style that never compromises function. That same philosophy carries directly into their line of brake rebuild kits.

Caliper Rebuild Kits Engineered for PM Calipers

Performance Machine offers caliper rebuild kits matched to their specific caliper families, including kits for their renowned 4-piston calipers — covering models such as the 125x4R, 125x4RSPH, 125x4SL, and 124x4S — as well as kits for their high-performance 6-piston calipers like the 112x6B. Each kit supplies the replacement seals and components required to properly rebuild one caliper, restoring hydraulic integrity and braking feel to like-new condition.

For riders who rely on PM's master cylinder hardware, brake master cylinder rebuild kits are also available, supplying everything needed to overhaul a single PM master cylinder. These kits are an essential maintenance item for any custom bike running PM hand controls, ensuring that fluid containment and lever feel remain consistent over time.

Why Source Rebuild Kits Directly from Performance Machine?

PM calipers are dyno-tested for superior stopping power, and that performance standard only holds up when the internal seals and components meet the same specification. Using Performance Machine's own rebuild kits — rather than generic alternatives — means the replacement seals are precisely matched to PM's caliper bore dimensions, preserving proper piston travel and preventing fluid seepage. Whether you're refreshing a set of Classic 4-piston calipers on a Harley-Davidson Touring model or maintaining a custom six-piston setup, the right rebuild kit keeps your brake system operating with the confidence PM's brakes are known for.
