Note.
- Necessary special devices, control and measuring instruments, as well as auxiliary means.
- A device for pressing the pedal, eg. "V.A.G 1869/2".
Removal
Note: This working method only applies to replacement or subsequent repair work on the disc brake caliper.
1. Remove the wheels.
2. Disconnect the plug connector of the brake lining wear indicator.
3. Insert the air bleed tube of the air bleed vessel onto the air bleed valve of the disc brake caliper and open the air bleed valve.
4. Install a device to press the pedal, eg. "V.A.G 1869/2".
5. After closing the air release valve, remove the air removal vessel.
6. Unscrew the brake hose.
7. Remove both caps from the disc brake caliper housings.
8. Having released both guide pins, remove them from the disc brake caliper.
9. Remove the disc brake caliper from the disc brake caliper support.
10. Remove the friction linings from the disc brake caliper.
Installation
Note: The piston is pressed back.
1. Install the inner friction lining (piston side) "1" and the outer friction lining "2" with a spring into the caliper of the disc wheel brake mechanism.
Internal friction lining (piston side) with a large three-pronged clamp "1".
External friction lining with small clamp with three tabs "2" (painted black).
2. Put the disc wheel brake caliper with friction pads first on the support of the disc wheel brake caliper at the bottom of the "arrow".
3. Screw the disc wheel brake caliper together with both guide pins onto the caliper support. The caliper pin of the disc wheel brake mechanism must be located behind the guide support of the caliper of the disc wheel brake mechanism.
4. Put on both caps.
5. Screw the brake hose onto the disc brake caliper.
6. Remove the pedal pressing device, e.g. "V.A.G 1869/2".
7. Connect the plug connectors of the brake lining wear indicator.
8. Remove air from the brake system.
9. Install the wheels.
Note.
- Press firmly on the brake pedal with the vehicle stationary so that the friction linings reach their working position.
- Check the brake fluid level.
