Product Details

Part number 99P17342A is a rear left brake caliper for the 2005 Buick LaCrosse and 2004-2005 Pontiac Grand Prix. The TechShield 360 (tm) line focuses on corrosion-resistant protection for brake hydraulics, and this caliper uses an aluminum casting with a rust preventative finish to support long-term service in demanding brake environments. The unit includes the bracket, slides, dust boots, hardware, and bleeder screw, and it is configured with a single 38 mm steel piston and a banjo bolt inlet.

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

What It Helps Address

• Rear brake drag caused by a sticking caliper piston
• Uneven braking from worn or corroded caliper components
• Brake fluid seepage at the bleeder or inlet connection
• Noisy or rough caliper movement from worn slides or boots
• Brake service needs on the rear left side of the vehicle

Installation Notes and Tips

Verify rear left placement, M10-1.5 inlet thread size, and banjo bolt connection before installation. Confirm pad fitment and brake hose condition during service, and bleed the hydraulic system after replacement to remove air from the circuit. Compare the housing cast number B3815 and vehicle application details when matching the part to the original caliper.
