Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm -VAG1331-
- Piston Resetting Tool -T10145-
Brake 1LB/1LC with Shims. Refer to → Chapter "Brake Pads, Removing and Installing, Brake 1LB/1LC with Shims"
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. Refer to → Chapter "Front Brakes"
Note
- Always replace brake pads on the same axle at the same time.
- Install complete repair kit. Refer to Parts Catalog.
- Install on one axle on brake pads from the same manufacturer and with the same quality.
- Use only mineral spirits or commercially available brake cleaner to clean the brake caliper.
Removing
Note
Label the brake pads that will be used again when removing. Install in the same position, otherwise the braking effect will be uneven.
- Remove affected wheel. Refer to →Wheel and Tire Guide; Rep. Gr.44.
- 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.
- Press the brake pistons back using the Piston Resetting Tool -T10145- with the brake pads still installed.
Position the Piston Resetting Tool -T10145- on the installed brake pad backing plates and carefully push the brake pads back into the brake caliper.
- Push a pad holding pin from the outside toward the inside out of the brake caliper.
Press the brake pad spring -8- inward for support.
Note
Be careful not to scratch or damaged the coating on the brake caliper.
Caution

- Clean brake caliper.
- Remove any protective film from the brake pad backing plate.
- Insert the new brake pads into the brake caliper.
Note
The brake pad and brake pad wear wire face the inside.

Make sure the brake pad spring is installed correctly.
- Push the brake pad spring -7- from the inside toward the outside through the hole in the brake caliper. Press the brake pad pin all the way, if necessary.
Caution
The brake pad pin needs to be seated securely in both holes so that it doesn't loosen on its own.
Note
- The brake pad spring -8- is located under the brake pad pin -7-. The spring on the end of the brake pad pin secure the brake pad pin inside the brake caliper.
