What It Helps Repair

• Brake fluid leakage at the caliper body or bleeder area
• Uneven braking caused by a sticking or seized caliper
• Corrosion or wear on the original front left caliper assembly
• Brake drag from damaged slides, boots, or piston sealing surfaces
• Brake service issues when the original bracketed caliper is no longer reusable

Installation Notes and Tips

Confirm front left fitment by year, model, and brake package before installation. This caliper is listed for 2012-2016 BMW 528i front left except performance brakes, plus 2012-2016 BMW 528i xDrive front left and 2011 BMW 528i front left. Verify inlet thread size, bleeder thread size, and bracketed caliper configuration against the original unit before bleeding the system.

Replace brake fluid as needed, inspect the hose connection and copper crush washers where applicable, and check pad wear, rotor condition, and slide movement during service. Proper torque and a complete brake bleed are important after caliper replacement.
