Product Details

PowerStop S3242 is a front disc brake caliper set engineered for BMW 325i, 325xi, 328i, and 328xi models from 2006-2007. The calipers bolt directly in place of the original front units and are finished in red electrostatic powder coating to help resist rust and corrosion. The aluminum casting, floating caliper layout, and 57.00 mm piston diameter support consistent brake response for daily driving and performance-focused use. PowerStop remanufactures the calipers and brackets in its Chicago facility, then pressure tests each unit before assembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons for Replacement

• Leaking or sticking front caliper piston
• Uneven brake pad wear from worn slide components
• Corrosion on the caliper body or bracket
• Reduced braking performance from damaged internal seals
• Restoring front brake function on a BMW 325i or 328i

Installation Notes

Verify front fitment by year, model, and position before installation. Transfer brake pads and related components as required by the vehicle setup, and inspect brake hoses, rotors, and pad wear surfaces during service. Bleed the brake system after installation to remove air and confirm proper pedal feel. The included mounting bracket and caliper slides simplify replacement on the confirmed BMW front applications.

Quality Assurance

Each PowerStop S3242 caliper is pressure tested for piston operation and leak verification before it leaves the remanufacturing process. New internal wear components, high-temperature dust boots, and stainless steel pad abutment clips are used during assembly to support consistent operation and corrosion resistance.
