Brake Shoe Assembly LK04458 5-87832-045-0 8-97035-085-1 for ISUZU NKR55 NLR85 NMR55 NKR85 — Verified OEM Fit Rear Drum Brake Shoe Set Ø300*75 mm
Product Overview
The Brake Shoe Assembly with reference code LK04458 and OEM number 5-87832-045-0 is a verified direct-fit replacement for ISUZU NKR55 / NLR85 / NMR55 / NKR85 / NKR66 / NKR69 / NHR55 light trucks equipped with 4JB1 / 4JG2 / 4HF1 diesel engines. This critical component generates braking force by pressing friction lining against the rotating brake drum when the brake pedal is applied.
Working Principle
This curved metal platform with bonded friction lining mounts inside the brake drum. When hydraulic pressure is applied, the shoe presses outward against the drum surface, converting kinetic energy into heat to slow the vehicle. Manufactured by YIMI (Guangzhou) Automotive Parts Co., Ltd., it features high-friction, non-asbestos organic (NAO) lining for reliable commercial performance.
Failure Symptoms
Squealing, grinding, or scraping noise during braking — worn friction lining allows metal-to-metal contact
Uneven or accelerated tire wear — dragging brake shoe from seized adjuster
Critical Inspection Note: ISUZU service manuals require brake shoes to be replaced as a complete set per axle for balanced braking performance. Always inspect brake drums for scoring, cracks, or excessive wear. Check wheel cylinders for leaks and measure drum inner diameter against service limits.
