Title: 3.2 rear brake disc removal (or not)
Post by: wadeyblue on 01 April 2011, 14:38:44
Tried to change the rear discs on my 3.2 this morning.
Jack up car, remove wheel, brake caliper and disc retaining stud.
Tried to remove disc with no luck, would not budge even when battered with a hammer.
Is there an easy way or a knack to doing this.
It is the original disc so has been on almost 9 years.
HELP

Handbrake off, and star adjusters used to slacken off shoes?

As Jimbob says, handbrake shoes. Follow the guide, should give enough clues how to release, and then reset properly afterwards :y

Almost certainly being held on by hand brake shoes.

I found it works if you pull up and down on the hand brake lever several times to give the shoes a bit of a "wake up".If auto they tend not to get used too much and have a habit of being very close to the internal drum.Have a good look through inspection hole with led torch to ensure star adjuster is turning as you wont get the discs off without slackeneing off those handbrake shoes.

If you just keep hitting it with lump hammer you will damage the hand brake shoes and end up needing to renew them aswell...but you will get disc off I suppose.

you have removed the trox bolt, as is if you keep hitting it you will soon need new back plates etc.

often the case when they have been on there a long time, just hit the edge of the disc with the big hammer and turn the disc after each whack it will come off but it is a bit frightening, the gap where the caliper was is best to knock it utward and anywhere else will knock it back and forth, just pretend you hate it and whack it!!
this is assuming of course you are replacing the discs!! if you are hoping to reuse them then ignore this post!!!

Ave it! Bigger hammer. If the hub rotates then the hand brakes not binding. They do need a real good smack sometimes.

Get underneath and slacken off the adjuster,you'll have to remove a heatshield first. The brake shoes tend to catch in a groove that has been worn into the drum part.
You can slacken off the one side at a time through the little hole in the drum/disc assembly. Trouble is knowing which direction to go! Its a right pain in the backend.
Far easier to slacken off as suggested,underneath where the cable splits in two,that way you are doing both sides at a time.

Thats incorrect I'm afraid, assuming the handbrake has been properly adjusted.  If that worked for you, then the idiot who last adjusted the handbrake did it all wrong  :'(

The only answer, if the shoes are stuck behind a lip, is to slacken the cable *AND* slacken the individual adjusters in each side.

Just done mine at 8 years old and they required a lot of 'percusion persuasion' with a 1 lb hammer but they did let go after a while. Don't smack the friction surface, it is likely to break and fly off into either a) somewhere you can't find and then will end up in a tyre, or b) your eyes, neither of which is good.

Patience works, and sometimes big hammers, but big hammers always break something when they land somewhere you didn't want them to.

The other thing I have done (on an old Granada) was to heat up the disc where it meets the hub flange with blowtorch (trying not to fry the wheel bearing) and then give it a solid smack with a smallish hammer.  That seemed to work too.

Best of luck.
