Common Problems This Part Can Address

• Sticking or uneven caliper piston movement
• Brake fluid leaks at the caliper body or seals
• Uneven pad contact caused by worn slides or hardware
• Corrosion or wear on the original front left caliper
• Reduced braking consistency from a failing hydraulic caliper

Installation Notes and Tips

Verify front left position, piston count, and bleeder thread size before installation. Inspect brake pads, rotors, and brake hoses for wear or damage during caliper replacement. Because mounting hardware is not listed as included, confirm whether your vehicle requires separate hardware before starting the job. Bleed the brake system thoroughly after installation to remove air and restore pedal feel. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

PowerStop remanufactures the caliper and bracket in its Chicago, IL facility and pressure tests each unit to verify piston operation and help prevent leaks. New seals, dust boots, bleeder screws, stainless steel pad abutment clips, and premium silicone lubricant are used during assembly to support consistent operation and long service life in demanding conditions.
