I know some of you may have seen this picture before,,,,well I have another customer who doesn’t know how to put on snow chains,,,but this time it did more damage the usual,,,,F10 rear brake damage. This time it cracked the parking brake motor which bolt onto the rear bake calipers ,,,,you can see part of the housing is cracked right where that electrical plug connects too. This is the  other side of the electric motor which bolts on to the rear brake caliper,,,,you can see the gear which turns the caliper . This is the back side of the rear brake caliper ,,,,you can see where the gear goes into the brake caliper ,,,,this is all sealed no brake fluid lose,,,,no calibration needed for the motors,,,,they are straight bolt on and plug in.
