Removal and installation rear brake calipers (BMW 5 Series E34)

Removal

Remove the decorative wheel cap.

Mark the position of the wheel rims on the rear wheel hubs with paint. This will ensure that the balanced wheel is subsequently installed in the same position.

Loosen the wheel bolts of the corresponding rear wheel. The vehicle must still be on the ground.

Raise the rear of the car and remove the wheel.



On the brake caliper of the right wheel, remove the connector of the wear sensor "arrow", but do not pull on the wire.

Unscrew the brake caliper mounting bolts 8 using a 17 mm open-end wrench and remove the caliper together with the installed brake pads from the brake disc.



Hang the brake caliper from the body using a homemade wire hook. Do not pull the brake hose.





If complete removal of the brake caliper or removal of the brake hose from the brake caliper is required, unscrew the brake hose "arrow" while holding the hose hexagon with a wrench. In other cases, the brake hose may not unscrew.

Caution: Collect leaking brake fluid in a bottle intended exclusively for brake fluid. You can also suck out the brake fluid from the expansion tank.

Installation

Place the brake caliper with the brake pads inserted onto the brake disc.

Tighten the mounting bolts of 1 brake caliper using a 17 mm open-end wrench to a tightening torque of 85 Nm.

If the brake hose was removed, wrap it at the point where it connects to the brake circuit. Remove air from the brake system.

On the right side of the vehicle, connect the wear sensor connector and secure it to the pillar.

Install the rear wheel observing the disc position marking on the hub. Lower the car and cross-tighten the wheel bolts to 110 Nm.

Note: With the vehicle stationary, press the brake pedal several times until you feel stiff resistance. This will cause the brake pads to approach the brake discs and take their working position.
