Product Details

Nugeon TechShield 360 (tm) 99P17930A is a rear left disc brake caliper engineered for vehicles using the listed bracketed rear brake setup. The cast iron housing, steel piston, and rust preventative finish support dependable hydraulic braking performance while the included bracket, slides, dust boots, and hardware help restore proper caliper movement and pad retention. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Part Can Address

• Uneven rear braking caused by a sticking or seized caliper
• Brake drag from worn slides, boots, or piston corrosion
• Soft or inconsistent pedal feel from caliper hydraulic leakage
• Poor pad contact due to damaged caliper bracket or guide hardware
• Brake noise related to worn caliper components and pad hardware

Installation Notes and Tips

Verify rear left fitment by year, make, model, and brake configuration before installation. Inspect the brake hose, banjo bolt sealing surfaces, and copper crush washers during replacement, and bleed the hydraulic system after installation to remove air from the circuit. Confirm the caliper slides move freely and that pad hardware is seated correctly before returning the vehicle to service.

Quality Assurance

TechShield 360 (tm) identifies Nugeon’s product line for brake hydraulics with a rust preventative finish and remanufactured construction. The part is built to match the listed OE-style fitment and hardware configuration for the specified rear left applications.
