Title: rear wheel grinding noise
Post by trol on Mar 8^th, 2009, 8:00pm

I'm hearing a grinding noise at the rear wheel lately.
It seems it's getting louder every time I drive the car :-/

It's one "grind" in one turn of the wheel.
It's not there when braking or accellerating, only when 'rolling".

I would think it's the brake disc, but I don't feel anything strange while braking.

What do you guys think?

Sounds like it could be the wheel bearing :)

almost deffo the wheel bearing, normally the drivers side, for some reason the 'boffins' at ford made them out of recycled tin cans then plonked 2 tonne of car on em, its a common fault..........

when you or a garage put them on make sure they're torqued to the specific amount, it is high about 200lb from what i remember, failure to do this WILL result in them failing a few months down the line...

trol.
Make very sure that the hubs are not worn,both bearings each side should be a firm press fit,if not there is a severe chance of premature failure.

It is 200ft/lbs and the further advice is to have them re-checked after a couple of hundred miles as they have been known to work loose even with the correct torque and loctite. ;)

I'm almost done on one side but I can't get the brake caliper to go in.
I realized I left the parking brake on while I removed the caliper.

Any ideas? :-[

The piston should wind in clockwise ;)

The rear pistons WIND back. You cannot press them back as with the front ones and ideally you need a 'wind back tool' which can be aquired for a few pounds. It is possible to use a pair of long nosed pliers BUT the correct tool makes life far easier. ;) Have a look at This page (http://www.draper.co.uk/Pages/Pagesource/p78.pdf) from the Draper catalogue. Works a treat. ;)

Sorry, should have said....'The piston should wind in clockwise while applying pressure' :)

The item Simmo is referring to is called a 'brake cube' & if you search ebay, is for sale for as little as £3.99. But if your in a hurry for one, then a good local motor factor should have them in stock :)

when replacing rear pads on my mk3,i use a g-clamp and a pair of curved jaw mole grips.the g-clamp puts pressure on the piston and the mole grips wind in the piston,after a few turns i retighten the g-clamp to keep the pressure on the piston,i do this until the piston is back in the caliper install new pads,refit caliper,..works everytime :).
