Brake Master Cylinder Kits
Brake Master Cylinder Rebuild Kits
Restore your braking system’s precision and safety with RPM Moto’s Brake Master Cylinder Rebuild Kits. These essential kits have everything you need—new seals, springs, pistons, rings, and grease—to renew your brake or clutch master cylinder without replacing the entire unit.
Why Rebuild Instead of Replace?
- Cost‑Effective Maintenance
A quality rebuild kit typically costs a fraction of a new master cylinder—saving you hundreds while restoring full functionality - Safety & Performance
Worn seals can cause spongy levers, leaks, or even brake failure. A timely rebuild revitalizes pressure delivery and braking confidence - Eco-Friendly & Convenient
Rebuilding extends the life of your existing assembly—less waste and fewer parts to manage
What’s In Each Kit?
- Master cylinder piston & return spring
- Rubber seals & O‑rings for leak prevention
- Snap‑ring, dust boot & washer/spacer
These components are crucial for restoring tight tolerances and smooth movement inside the master cylinder.
When Is a Rebuild Needed?
Look out for these warning signs:
- Soft or sinking brake or clutch lever
- Leaks or fluid pooling around the lever perch
- Spongy feel or inconsistent braking
- Difficulty in bleeding the system
If you spot any of these, a rebuild kit is likely overdue.
Fitment & Installation Guide
- Check compatibility: Kits are bike-specific—match make, model, and master cylinder size.
- Clean workspace: Rebuild in a dust-free environment to avoid seal contamination
- Use correct tools: Snap-ring pliers, torque wrench, and bleeder tools recommended
- Bench-bleed before install: Pre-fill and bleed the unit to remove air bubbles
- Re-bleed after install: Ensure pedal feel is firm and hydraulic pressure is consistent
