Front brake disc (VW Golf 2)

The brake disc must not be thinner than the value specified in the technical data. Before measuring, the disc must be cleaned. The thickness is measured with a caliper or micrometer. The second important parameter is the so-called disc runout. The maximum runout is specified in the technical data. The runout of the friction surfaces of the disc is measured with a clock sensor. If any parameter does not correspond to the permissible value, the disc must be replaced. If the disc is thick enough and is only scratched or has a runout greater than the permissible value, it can be ground at the plant.

To remove the disk you need to:

1. Perform the actions described in paragraphs 9.1-9.6.

2. Unscrew the screw and remove the disk from the hub (photo 8.22).



3. If necessary, remove the brake disc cover after unscrewing the three bolts from the return mechanism.
