Detailed Description

Nugeon 99P17317A is a rear left disc brake caliper engineered for heavy-duty GM truck brake service. It uses a cast iron housing, phenolic pistons, and a rust preventative finish to support dependable hydraulic operation in the rear brake system. The TechShield 360 line covers brake hydraulic components for applications that require a bracketed caliper assembly, and this unit is listed with the bracket included for the specified Silverado 3500 and Sierra 3500 fitments.

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

What It Helps Fix

• Brake fluid leakage at the rear left caliper
• Uneven rear braking caused by a sticking caliper piston
• Brake drag from worn internal seals or slides
• Corrosion-related caliper housing wear on heavy-duty trucks
• Poor pedal response from a failing rear brake hydraulic assembly

Installation Notes and Tips

Verify rear left position, dual rear wheel configuration where required, and inlet thread size before installation. This caliper uses a banjo bolt inlet fitting with M10-1.5 inlet port threading and includes a bleeder screw. Transfer or replace brake pads as needed, and follow proper bleeding procedures after installation to remove air from the hydraulic system. Confirm bracketed caliper style and match the housing cast numbers when comparing to the original part.

Part number 99P17317A is built to match the specified GM truck fitment and brake system requirements.
