Replacing the brake disc (Renault Logan 1)

If there are burrs, deep scratches and other defects on the working surface of the disc that increase pad wear and reduce braking efficiency, as well as in the case of increased lateral runout of the disc that causes vibrations during braking, replace the disc. In specialized workshops, such a disc can be turned and ground on both sides to the same depth, but after processing, the thickness of the disc must not be less than the minimum permissible.

The minimum permissible thickness of the brake disc is 10.6 mm. If the thickness of one of the discs is less than the specified value, replace both discs. When replacing the brake discs, be sure to replace the brake pads with a new set.

You will need a TORX T30 key.

1. Remove the wheel from the side of the disc being replaced.



2. Remove the caliper assembly (see "Replacing the front wheel brake caliper"), without disconnecting the brake hose, and secure with wire, preventing the hose from twisting or being pulled.



3. Loosen the two screws securing the brake disc to the front hub...

4. ...and remove the brake disc from the front wheel hub.

5. Remove the right brake disc in the same way.

6. Install the parts in the reverse order of removal.

Note: Before installing the disc, thoroughly clean the mating surfaces of the hub and disc from rust and scale, since even the smallest particle clamped between the mating surfaces will cause disc beating and vibration during braking.

Note: If you are installing the same disc, use a file to remove the ridges on the working surfaces of the disc that have formed on both sides as a result of wear.
