Rear Right Brake Caliper - 2011 528i

The BMW F10 5-Series rear right brake caliper integrates the service brake piston with the electric parking brake mechanism, making it a high-failure component in 2011 528i models. The correct replacement is BMW part number 34216799464, superseded by 34216850882, which interchange across 2010-2016 528i and 530i sedans equipped with the N52 or N53 engines. Avoid calipers from 535i or 550i donors, as these utilize larger 42mm pistons incompatible with the 528i's hydraulic bias. When inspecting junkyard units, verify the casting isn't cracked at the EPB motor mount bracket and that guide pins move freely without pitting. Installation requires retracting the parking brake motor via ISTA diagnostic routine or manual emergency release before piston compression—forcing the piston destroys the internal gearbox. Always replace copper crush washers at the hose banjo bolt and bleed the DSC hydraulic unit to restore pedal feel.
