Built for Brake System Restoration

This MPA Electrical disc brake caliper is remanufactured at an IATF 16949 facility using a controlled inspection process. Heavily pitted or severely corroded cores are removed before rebuilding, while reusable steel components are cleaned, inspected, and verified before assembly. Threads are chased for OE-style fit, rubber components are material tested, and the caliper receives a corrosion-resistant coating for added protection. This part cross-references 542134 for the same application. Use BC154638 when servicing a front left brake caliper on a 2004-2005 Buick Century, 2000-2005 Buick LeSabre, 2005 Cadillac DeVille, or other listed GM models.

Common Problems This Part Can Address

• Brake fluid leakage from a worn or damaged caliper body
• Uneven braking caused by a sticking or seized piston
• Poor pad contact from corroded internal components
• Brake pull related to a failing front left caliper
• Reduced braking performance from worn caliper slides or bracket wear

Installation Notes

Verify vehicle fitment by year, make, model, and brake configuration before installation. This caliper is for the front left position and is listed for standard duty or standard caliper applications where noted. Transfer only approved reusable components as needed, bleed the brake system after installation, and inspect hoses, pads, and rotors for wear before returning the vehicle to service. BC154638 is also a direct replacement choice for 1997-2004 Buick Regal, 1997-2003 Pontiac Grand Prix, and 1997-2004 Oldsmobile Silhouette front left applications listed in the fitment data.

Quality Assurance

MPA Electrical remanufactures this caliper through multiple QC checkpoints, including core inspection, final assembly checks, thread verification, and go/no-go testing before release. Aluminum caliper inlet areas are machined for sealing where applicable, phenolic pistons are replaced with new components during teardown, and cast iron calipers receive zinc dichromate corrosion protection for OE-style appearance and rust resistance.
