Removal
1. Remove the front wheel.
Note.
- Mark the friction linings when removing them (internal, external), which will be used again. They must be re-mounted in the same place, otherwise the braking effect will be uneven.
- When replacing the friction linings, do not disconnect the brake hose from the disc brake caliper.
2. Disconnect the connector of the brake lining wear indicator (if the car is equipped with it).
3. Remove the plugs (1) shown in the figure below.
4. Remove both guide bolts (arrows) from the disc brake caliper as shown in the figure below.
5. Remove the disc brake caliper (1) and hang it using wire so that its weight does not exert any load on the brake hose.
6. Remove the friction linings (2) and (3) from the disc brake caliper as shown in the figure below.
Installation
Note.
- Before pressing the piston in, remove the brake fluid from the expansion tank using a bleeder.
- To clean the body of the disc brake caliper, use only alcohol.
1. Clean the disc brake caliper.
2. Press in the piston using the piston installation tool (MP9-403) as shown in the figure below.
3. Install the inner friction lining (piston side) (1) and the outer friction lining (2) with a spring into the disc brake caliper, as shown in the figure below.
Internal friction lining (piston side) with a large three-pronged clamp (1).
External friction lining with small clamp with three legs (2) (painted black).
Note: Do not frighten the inner and outer friction linings. Follow the markings.
4. Install the friction lining with the black clamp and three tabs into the disc brake caliper housing.
5. Install the disc brake caliper from the bottom first.
6. Install the disc brake caliper with friction linings onto the wheel bearing cap. The disc brake caliper journal (arrow) should be located behind the wheel bearing cap guide, as shown in the figure below.
7. Screw the disc brake caliper with both guide bolts (arrow) onto the wheel bearing cap as shown in the figure below.
8. Connect the connector of the brake lining wear indicator (if the car is equipped with it).
9. Install the guide pin covers.
10. Install the wheel.
Note: After any replacement of the friction linings, it is necessary to press the brake pedal with the vehicle stationary so that the friction linings are set to the working position.
