Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm -VAG1331-
- Piston Resetting Tool -T10145-
Note
If old brake pads are being replaced with new ones, then it is necessary to check the brake rotor for wear. Pay attention to the brake rotor wear limit while doing this.
Removing
Note
When removing, mark brake pads that will be used again. Install in the same position, otherwise braking effect will be uneven.
- Remove affected wheel. Refer to →Wheel and Tire Guide; Rep. Gr.44.
It is not necessary to remove the brake caliper in order to remove the brake pads
- Disconnect the connector for the brake pad wear wire.
- Unclip the brake pad wear wire.
Caution
Danger of contamination and paint damage from escaping brake fluid.
- If the brake pads are worn out and brake fluid is filled, the brake fluid may overflow if the pistons in the brake cylinder are pressed back.
- Check the brake fluid level before pressing back the pistons. If there is brake fluid up to the "MAX" mark, some brake fluid will need to be extracted.
- Use the Brake Charger/Bleeder Unit -VAS5234- to extract brake fluid from brake fluid reservoir.
