Removal and installation of a forward brake disk

Withdrawal

Mark the position of the wheels on the hub with paint in order to install them in their original place during assembly. Loosen the wheel nuts with the vehicle lowered. Raise the front of the car and remove the front wheels.



Remove the mounting bolts and remove the brake caliper from the steering knuckle, hang the caliper on the shock absorber strut on a wire hook. In this case, the brake hose must not be stretched or kinked.

If necessary, use a small screwdriver to remove the two stoppers from the wheel studs. Remove the brake disc.

Installation

In order to ensure the same braking force on both sides, it is necessary that both brake discs have the same surface roughness. Therefore, replace both disks at once, or grind them. At the service station, the end runout of the disc is checked. The maximum runout is given in clause 15.1.

Measure the brake disc thickness.

If necessary, remove rust from the brake disc flange and front wheel hub with a soft metal brush.

Clean the new brake disc with a nitro thinner to remove the protective coating.

Install the brake disc on the wheel hub and secure with two stoppers, putting them on the threads of the two opposite wheel studs.


Install the brake caliper with pads and fasten to the steering knuckle with a torque of 120 Nm.

Install the front wheels so that the marks made earlier coincide. Apply a light coat of grease to the centering surface on the wheel hub before installing the wheels. Screw on the wheel nuts. Lower the vehicle and tighten the nuts crosswise to 100 Nm.

Attention! Depress the brake pedal several times until you feel good pedal resistance. Thus, the pads will press against the brake disc and take their working position.

Check the fluid level in the expansion tank, top up if necessary "MAX".
