Maintenance/improvement Tips - 4.2

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.

Welcome to the club.

You've got some run out somewhere. On a 4.2 the rears can give problems as well but you will have to just look around. If it is a rear you might be able to hear it when you brake - a rumbling noise either with or without your foot on the brake. Failing that you need to jack the wheels up one by one and turn them Look at the discs and eyeball how they run in comparison to the pads. If you can feel it on the pedal you will see the run out. If you can't see it with the wheels on you will have to take them off but be sure to run a couple of nuts up to the disc or it will woabble about anyway. As longs as you made a good job of cleaning the hubs before putting the new discs on I think it would be a good idea to start at the back. Keep in mind they will be stiff to turn so use a piece of wood or a lever through the wheel studs and you need them fronts chocked securely while the handbrake is off.

Hi Anchorman, I have a 2002 Rav4 D4D and need to replace the rear pads. Can you push the piston back in with a G clamp like on the front?

[Helirazor]

Sorry Anchorman, I have now found the section on doing the rear pads!

Thank you so much for your time and effort in compling such a comprehensive account, it is very much appreciated!

I don't need to change my brakes yet.

I have to say though this is the best guide I have seen.

So will save me a fair few quid in the future.

Cheers anchorman for all the great work :)
