All Balls Racing – Caliper Rebuild Kits, including rear kits for the 92-98 Honda CBR400, 04-15 Honda CBR125, 93-95 Suzuki GSXR750, 11-22 Suzuki GSX-R600 and 88-90 Kawasaki ZX1000 Ninja ZX10, front kits for the 1990 Honda CB125TT and 17-18 Honda CB300F ABS, and the 92-93 Suzuki GSX-R600 front brake pad retaining pin kit. Street calipers fail from time and neglect more than from mileage: brake fluid absorbs water, the piston bore corrodes under a hardened dust boot, and one piston stops retracting. What you feel is a lever that never quite comes back, a rotor cooking on one side and pads wearing at an angle. These motorcycle caliper rebuild kits supply the square-cut piston seals, dust seals and boots sized to the original bore, so the caliper you already have gets full travel and even clamping again. Rebuilt calipers give you a firm lever with real feel at the fingertips, which is what lets you trail-brake into a corner with confidence. Fresh grease on the pins and sliders keeps the new seals working season after season. Tell us your year, model and front or rear position and we will confirm the correct kit before you order.
