Front brake pads and discs - Part 2

Part 2

Discs

On this car I changed the discs. In this case, remove the upper caliper bolt;

remove the caliper and hang it off the spring. Do not allow it to hang on the brake pipe;

Then undo the retaining bolts and remove the carrier;

If you intend using the disc again you should use 2 - 8mm bolts in the extraction holes as shown on this rear disc;

Wind the bolts in until they apply pressure then gently tap the disc from behind. If you don't have a hide or rubber mallet use a piece of wood against the disc and then hit that with the lump hammer. In this case they were scrap so a swift smack with a lump hanner from the back side will knock them off. Clean the disc with white spirit;

......and the hub mating face with a wire brush;

Then degreaser to get the hub as clean as you can you can;

Clean the carrier;

Then put the disc on the hub and refit the carrier - 98Nm (72ft/lbs)

The discs are not fixed, they are trapped between the wheel and the hub. If you have problems with them trying to fall off use a couple of wheel nuts backwards to hold them in position while you work (rear disc shown);

Now reassemble the caliper and pads as shown in part 1.
