Installation
Note: Before pressing the piston, suck out the brake fluid from the hydraulic brake fluid reservoir. Otherwise, if any brake fluid has been added, it may leak out and cause damage. When returning the piston to its original position using the device, the automatic adjustment in the brake mechanism support is disrupted. Screw in the piston by turning the knurled wheel of the device for setting to the original position "T10165", while taking care not to damage the protective cap. For screwing in, use the special device "T10165/1" as an auxiliary tool. In case of tight piston movement, you can use an open-end wrench, setting it on the chamfers intended for this purpose "see arrow A".
Note: To depress the piston, it is necessary to simultaneously turn the reset device "T10185" to apply pressure to the piston.
Install new "arrow" brake pads into the brake shield. Remove the protective film from the outer brake shoe support plate. Carefully install the brake caliper onto the brake shield.
Note: The repair kit contains four self-locking screws that must be installed.

Secure the brake caliper to the brake shield using new self-locking screws. When tightening the screws, hold the guide pin to prevent turning. Connect the connector of the brake pad wear indicator (if the vehicle is equipped with them - only on the right side of the vehicle).
Note: After each replacement of the brake pads, press the brake pedal hard several times with the vehicle stationary, so that the brake pads reach their working position. After replacing the brake pads, check the brake fluid level, and top up the brake fluid if necessary.
Press the brake pedal hard several times with the car parked. Adjust the parking brake. Install the wheel.
