The BMW Z4 Door Brake / Stop, OEM part number 7051746 (also replaces 7176806), is a used genuine part. This front component, which fits both left and right sides, controls the door's opening arc and holds it in position. A worn door brake can cause the door to swing freely or fail to stay open on an incline. This part is for 2.5L, 3.0L, and 3.2L naturally aspirated inline-six engines.
