BMW Z3 Brake Booster

The BMW Z3 Brake Booster certainly makes it easier to stop the car by amplifying the force that is transmitted to the master cylinder. Mounted between the pedal and cylinder, the Brake Booster assists in creating this extra push through either engine vacuum or hydraulic pressure. Many Z3 cars use a vacuum shell with a diaphragm in it, where the vacuum is the same until the pedal opens a valve to allow outside air to fill the rear chamber, which in turn causes a pressure difference that pushes the piston forward. Certain later trims of the BMW performance models use a hydraulic Brake Booster powered by the power steering pump or electric motor, so brake assistance is maintained at all times when there is a weak vacuum. The vacuum unit remains light and reliable, and the hydraulic option provides steady assist at full throttle or forced induction running, which is a trade-off that owners like. Releasing the pedal evens out the pressure, immediately preparing the system for the next stop. With the engine off, the booster stores only a couple of assisted presses, so BMW drivers should brake early in case of loss of power. Overall, the Z3 Brake Booster converts small amounts of foot pressure into confident deceleration, an important component that maintains the sharp feel of stopping that is expected from every BMW. Regular function of the Brake Booster keeps the nimble Z3 safe.

BMW Z3 Brake Booster Parts Questions & Experts Answers

  • Q:
    How to remove and install the brake booster and master cylinder on BMW Z3?
    Posted by Rafal F.
    A:
    To remove and install the brake booster and master cylinder, first disconnect the negative battery cable and siphon the brake fluid from the reservoir. Remove the reservoir and, if applicable, disconnect the clutch hydraulic hose. Disconnect all brake lines from the master cylinder and remove the instrument panel trim from the bottom left inside the passenger compartment. Take off the return spring from the brake pedal, press off the clip, and remove the pin connecting the booster rod to the brake pedal. Remove the four nuts and pull the booster and master cylinder out of the engine compartment. For installation, if the filter in the brake booster is clogged, clean it by removing the dust boot, retainer, damper, and filter, ensuring that the slots in the damper and filter are offset by 180 degrees upon reinstallation. Install the brake booster and torque the nuts to 16-17 ft. lbs. (22-24 Nm), then connect the brake lines and torque them to 10 ft. lbs. (14.2 Nm). Reconnect the reservoir and lines, attach the brake pedal to the pushrod, adjust the pedal height and Brake Light Switch, and finally fill and bleed the system.
