Detailed Description

Nugeon 99P17397A is a rear left disc brake caliper engineered for GM full-size trucks and SUVs that use this brake hydraulic configuration. It is listed for the Chevrolet Tahoe, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500, GMC Sierra 1500, and related applications across the 2007-2020 model years. The TechShield 360 line focuses on corrosion resistance and brake system durability, while the aluminum housing and rust preventative finish support long-term service in demanding road conditions.

This caliper includes a phenolic piston, bleeder screw, bracket, slides, dust boots, and brake pad installation hardware. The inlet uses a banjo bolt connection with M10-1.0 thread sizing, and the bleeder screw uses M10-1.0 x 32 threading. Part number 99P17397A is a direct-fit style replacement for rear left brake service on vehicles such as the Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon when the listed fitment matches the original brake setup.

What This Caliper Helps Address

• Rear brake drag caused by a sticking caliper piston or slide hardware
• Brake fluid seepage at the caliper inlet or bleeder area
• Uneven rear braking on the left side
• Corrosion-related caliper seizure on GM truck and SUV brake systems
• Brake pad wear issues tied to worn caliper hardware

Installation Notes and Tips

Verify rear left fitment by year, make, model, and brake configuration before installation. This caliper is supplied with a mounting bracket and uses a banjo bolt inlet connection, so confirm the original hose and fitting style match the vehicle. Inspect the brake hose, pads, rotor, and mounting points during service, and bleed the brake system after installation to remove air from the hydraulic circuit.

For 2019 Chevrolet Silverado 1500 LD and 2019 GMC Sierra 1500 Limited applications, confirm the manual parking brake configuration noted in the fitment data. The part number 99P17397A should be matched to the original rear left caliper layout before assembly.

Quality Assurance

Nugeon TechShield 360 is positioned as a corrosion-conscious brake hydraulics line, and this remanufactured caliper is built with aluminum construction, a rust preventative finish, and included service hardware for a complete brake repair path. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
