8-98302529-0 REPAIR KIT; CALIPER,DISC BRK,FRT ISUZU for NHR/RZ4E

Restores Hydraulic Sealing and Sliding Surfaces

This repair kit is a comprehensive set of wear‑sensitive components for rebuilding a front disc brake caliper. It includes high‑quality rubber components such as the piston seal, dust boot, and guide pin boots, along with necessary hardware like new crush washers. The kit is designed to restore the caliper's hydraulic sealing and sliding surfaces, ensuring the piston moves smoothly and retracts correctly after braking .

EPDM Rubber Construction for Brake Fluid Resistance

All rubber elements are made from a high‑grade EPDM compound, specifically chosen for its resistance to glycol‑based brake fluid, heat, and aging . This robust construction stops fluid leaks, blocks dirt and moisture from entering the caliper bore, and prevents sticking pistons that cause uneven pad wear . The kit is used across a wide range of Isuzu applications, including the 4JK1‑TCX engine in the D‑MAX and models like the TFR/TFS pickup family and NPR trucks . Genuine part numbers for this kit include 8980791050, 8983025290, and 8983025320 .
