ALL BALLS offers this brake caliper rebuild kit for YAMAHA YFM 550 GRIZZLY 4WD, YFM 550 GRIZZLY EPS 4WD, YFM 700 GRIZZLY EPS 4WD, YFM 700 GRIZZLY EPS XT-R 2007-2025. The caliper is the clamp that squeezes the pads onto the disc. Inside, one or more pistons are pushed out by the brake fluid when you pull the lever or press the pedal.

Why rebuild the caliper?

The benefits:

• Pistons that slide freely: the pads stop rubbing and wear evenly.
• Precise, consistent braking, even after muddy rides and repeated washing.
• You keep your original caliper, already matched to the bike.

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?

A brake that drags or runs hot, pads worn at an angle, a scored, pitted or sticking piston, fluid around the piston: the caliper needs rebuilding.

Specifications and fitting tips

• Manufacturer part number: 18-9040

Cross-Mania tip: Clean the seal grooves without scratching them (plastic or wooden tool), coat seals and pistons with fresh brake fluid, grease the slide pins with a brake-compatible grease, then bleed the system.
