BMW 34211101760 Wheel Brake Cylinder

Jack up the rear of the car and remove the road wheel and the brake drum. Turn the shoe adjusters to their maximum adjustment position. To minimize loss of hydraulic fluid, place a piece of plastic sheeting under the fluid reservoir cap and screw the cap on tightly. Disconnect the fluid inlet pipe from the wheel cylinder, then unscrew the bleed screw and the cylinder securing bolts. Prise the upper ends of the brake shoes slightly apart and withdraw the wheel cylinder. Refitting is a reversal of removal, but adjust the shoes and after removing the plastic sheeting, bleed the hydraulic system.
