The wear parts of a brake or clutch master cylinder (piston, seals, diaphragm) to rebuild it instead of replacing the whole unit.
ALL BALLS offers this master cylinder rebuild kit for KTM SMR 450, SX 450, SX 505, SXF 450, XCF 505 2009-2011. The master cylinder is the pump at the lever (or pedal): when you squeeze, its piston pushes fluid down the hose to the brake caliper or the clutch slave cylinder.
Why a rebuild kit?
The benefits:
- A firm, consistent lever again, without buying a whole new master cylinder.
- The kit groups the parts that wear together: everything is changed in one go.
- You keep your original master cylinder, its adjustments and its mountings.
Why choose ALL BALLS?
Complete All Balls kits: low-friction bearings and steel-spring nitrile seals, everything you need in one box.
When should you replace this part?
Fluid weeping at the lever or pedal, a lever that goes soft or comes back to the grip, a cracked or distorted diaphragm: rebuild the master cylinder.
Specifications and fitting tips
- Manufacturer part number: 18-4005
Cross-Mania tip: Clean the bore with brake fluid and check it is neither scored nor pitted, fit the seals coated in fresh fluid, then bleed; only use the specified fluid (DOT or mineral oil).
