Rear Left Disc Brake Caliper for GM Trucks and SUVs

Nugeon 99P17306A is a remanufactured rear left disc brake caliper built for select Cadillac, Chevrolet, and GMC applications. It uses a 2-inch phenolic piston, aluminum casting, and a rust-preventative grey finish to support consistent braking performance on the rear axle.

This caliper is supplied with a mounting bracket, caliper slides, dust boots, bleeder screw, and brake pad installation hardware, making it a direct replacement for the listed rear left applications.

Detailed Application and Design

This rear left caliper is engineered for vehicles that use a 2-piston rear brake setup, including 2001-2002 Chevrolet Silverado 1500 and GMC Sierra 1500 models with the specified caliper configuration, as well as 2005 Silverado 1500 and Sierra 1500 trucks with JC4, JH2, 2-wheel steering notes. It also covers 2002 Chevrolet Suburban 1500 and Tahoe, plus 2002 GMC Yukon and Yukon XL 1500 applications with ribbed caliper casting notes. The 45 mm phenolic pistons help reduce heat transfer, while the included bracket and slides support proper caliper alignment during service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Caliper Helps Address

• Rear brake drag caused by worn caliper slides or piston seals
• Uneven rear braking from a sticking left-side caliper
• Brake fluid seepage at the bleeder or inlet connection
• Corrosion-related caliper wear on high-mileage GM trucks and SUVs
• Poor pad contact from damaged or seized caliper hardware

Installation Notes and Tips

Verify rear left fitment against the vehicle’s brake configuration, including 2-piston caliper notes, steering notes, and casting requirements listed for the application. Confirm the banjo bolt inlet, M10-1.0 thread size, and bleeder screw specification before installation. Transfer or replace brake pads as needed, and bleed the hydraulic system after installation to remove air from the circuit.

Quality Assurance
