Removal
Mark the position of the wheels on the hub with paint so that they can be installed in the same place during assembly. Loosen the wheel nuts on the lowered car. Raise the front of the car and remove the front wheels.
Unscrew the mounting bolts and remove the brake caliper from the steering knuckle, hang the caliper on the shock absorber strut using a wire hook. The brake hose should not be stretched or twisted.
If necessary, remove the two stoppers from the wheel studs with a small screwdriver. Remove the brake disc.
Installation
In order to ensure equal braking force on both sides, it is necessary that both brake discs have the same roughness of the working surface. Therefore, replace both discs at once, or grind them. At the service station, the end runout of the disc is checked. The maximum runout is given in paragraph 15.1.
Measure the thickness of the brake disc.
If necessary, remove rust from the brake disc flange and front wheel hub with a soft metal brush.
Clean the new brake disc with nitro solvent to remove the protective coating.
Install the brake disc on the wheel hub and secure it with two stoppers, placing them on the threads of two opposite wheel studs.
Install the brake caliper together with the pads and secure it to the steering knuckle with a torque of 120 Nm.
Install the front wheels so that the marks applied earlier match. Before installing the wheels, lubricate the centering surface on the wheel hub with a thin layer of grease. Screw on the wheel mounting nuts. Lower the car and tighten the nuts crosswise to a torque of 100 Nm.
Attention! Press the brake pedal several times until you feel good pedal resistance. This will press the pads against the brake disc and take their working position.
Check the fluid level in the expansion tank and top up to the "MAX" mark if necessary.
