Replacing Rear discs/pads & adjusting handbrake on a classic

Cars actually a 2000 uk turbo,Dead straight forward this even down to adjusting the handbrake shoes.(writing this assuming limited mechanical knowledge-know alot of you will know the score)


Basically your footbrake works the caliper and pads + the handbrakes on brakeshoes.


On the inside of the rear discs theres like a small drum this is for the handbrake only.


Tools needed- Hammer(for getting the old discs off),14mm socket,14mm spanner,flathead screwdriver + maybe some WD40.

This wont apply to many of ya im guessing but i have to drive mine up onto blocks to get the jack under




[IMG]http://img.photobucket.com/albums/v365/scoobymad/others/2006_0101today0130.jpg[/IMG



Once you`ve removed the wheel you need to undo these 2 bolts(identical bolts each ends of caliper-lol dont touch bleed nipple that it looks like arrow goes to pmsl) on your caliper and slide caliper out away from your disc-if you were only replacing pads and the disc were in good condition this is all you`d need to undo as once the calipers seperated pads will just slide out+slide new ones in,though with mine usually once the pads are knackered the discs usually are.



once the calipers seperated youre left with the caliper mounting bracket which holds the pads however is pictured here with the old ones out (pic werent needed with them in its obvious they just slide out)




The only other 2 bolts to undo are what hold this bracket and are found close to where the others were you`ve already undone.



You`ll now need the hammer to hit the rear of the disc where the caliper and brackets been removed-the discs gotta come off square to leave the handbrake shoes in position so hit the disc till ya start to see the brakeshoes slightly poking out at the back then hit the disc back to try and release the opposite side worth spraying some wd40 round the centre and stud holes as occasionally the disc will rust to the hub another time could just slide of without the need for a hammer at all.


Once the other sides slightly loose (if vented discs)put flathead screwdriver through vented part of disc then hit the shaft as close to the disc as possible towards you then in turn hit where the calipers been removed on the back of the disc and just alternate between the two keeping the disc sliding off the handbrake shoes as square as possible.




If you dont keep this process fairly square could end up with the shoes and a handfull of springs coming with the disc an trust me its a nightmare trying to sort where everything goes(usually ends up with ya removing otherside or finding some pics on the net)either way causes unnecessary aggro.



(bolts go through from the back through these holes into caliper mounting bracket as mentioned earlier)




This is the adjuster for the shoes generally i`ll adjust them so they`re just very slightly rubbing on the drum(inside of disc in this case) when you move the disc




Pic of insides of a rear disc showing if ya like the drum part



The discs are supplied with a light oil coating to protect them from rusting, always remove this with white spirit or equivalent on a cloth-it has to come off.

If the disc slides over the shoes straight away i`d adjust untill theres very slight resistance when pushing disc over the shoes,not so much as its going to bind im talking really slight resistance.


You can move the adjuster one tab at a time(as many as necessary) as the spring that joins both shoes above it are what the tabs locate against each time its turned.


If ya cock up and adjust up too tight and cant get the disc back off or you just want to adjust your handbrake shoes without replacing anything theres a rubber bung that goes through the backplate where the adjuster is, remove the bung then you`ll need a torch and flathead screwdriver to flick the tabs on the adjuster round-can only move one way or the other you`ll be able to tell which is which by trying to move the disc.




Once you`re at this stage just a matter of bolting the caliper mounting bracket back over the new disc sliding the new pads in,then retracting the piston in the caliper to allow for the extra width of new pads and sliding the caliper back over them and bolting back together.

(will probably either need some large grips or use as i do(if you have any)welding grips as in pic below to move caliper pistons bk in,mine are like the ones to the right here)





Ive dropped some copperslip grease in the clips where the pads move slightly as they were corroded a bit and you want your pads to move as freely as possible(not essential just something ive done)





Always worth pulling the handbrake up to centralise the shoes once complete then checking play with the handbrake off at the disc like i say like em just slightly(very slightly)rubbing on the disc/drum, again will hear when you move the disc slightly-occasionally it`l need another click on the adjuster by removing the bung to get at it through the backplate.


Job done,worth remembering untill theyre bedded in brakes will be average at best so dont go mad straight away you`ll know yourself when theyre bedded in ok,im gonna get some new handbrake shoes at some point(they`re cheap) so i`ll update this then and also paint the centre of the disc as it`l virtually rust straight away.


Any questions ask but it really is so easy(2nd time ive done it this, time took just over an hour for both sides though I could have been quicker but were pissing about taking pics )


Many thanks to Alyn at AS Performance - Rally Motorsport Specialists for supplying the pads(great service as always cheers mate)

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

It all depends on how long they`ve been on for,as if theyre adjusted up right where the shoes arent in contact slightly with the drum on the back edgeof the drum part you`ll get a build up of rust aswell as that being the natural thickness of the drum whereas it`l wear thinner where its in contact so you`re then in a position where the shoes dont want to let the drum/disc come towards you-its actually easier to wind the adjuster off first from behind through the backplate before removing,but half the time ya can get away without it if youre steady(saves a bit of time)if theyre a bitch though an the discs loose on the hub just wind the adjuster off then try again.


Ive done other cars where they`ve been that tight everythings come off with the drum an pulled the shoe retaining pins through the caps that push an twist over the sml springs that hold the shoes tight.

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

All i can say is what a fantastic guide, done my rears today, discs and pads and all the info you gave was truely superb, had abit of apain trying to get the old discs off but as soon as i slackened the adjuster from behind the disc s it both near enough fell off lol.
Bit of a swine trying to push the drivers side piston in, thought it was going to need a new caliper a one stage but went and bought a decent heavy duty metal g clamp and worked a treat, freed it right up and both seem to be working fine. Thanks Dave

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

No probs mate,always suprises me on here how many ppl`s actually done stuff to their cars yet nobody or very few post how and a few pics to show others,i know its a pain in the arse taking pics and then a short write up just wish more would do it.


You`ve no idea how long it takes me to type posts out with me 1 finger typing im just trying to cover the unusual stuff.

Soon(within the next wk) im gonna put a short vid up of cleaning out the boost solenoid as mines a bit hit an miss at low revs at the mo.

Good guide and also if the discs hard to get off you can screw in 8mm bolts into holes provided on disc if it nearly seized to hub comes in handy somtimes

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

Thanks for the excellant guide on how to do this job, the most usefull one i have found.

I'll be tackling the job next weekend waiting for better weather. I pressume the fronts would be a very similar operation, i have not got around to looking at those yet and really want to do them at the same time.

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

They`re all pretty simular to be fair, only the later classics with the 4pots on the front thats different,the caliper doesnt need to seperate as the pads are held in by 2pins and 2 clips.

Theres 2 solid pins with a head on one end(goes caliper outer facing side) that go through from one side to the other, one at the top + one at the bottom of the pads,theres a small hole in each of these pins the other end that a wire clip running vertical joins both pins up at the rear and the centre of the wire pushes through a hole in the caliper this keeps both pins in place,the other clip is a flat curved sprung clip that goes over both pins on the open middle part of the caliper and supports the pads at the back.

If you were removing the caliper to change the disc the caliper comes off the hub carrier in one piece not 2.

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

i had a go and doing my rear discs and pads after doing my front wheel bearing, to cut a long story short the front drive flange was so warn i had to replace that and the bearing, then on the rear discs for the life of me i couldnt get then buggers off until i read this post and found the illusive adjuster for the handbrake but they still wouldnt break free and as mentioned above the little retainer clips, springs and pins that hold the shoe inplace all pulled thru! so at the moment ive no handbrake!

i advise to loosen the adjuster all the way in before you try to tickle those buggers off, i slacked the calbe on the handbrake itself. ive changed discs and pads on a good range of cars but these were by far the worst! just need to put my new shocks and 35mm springs and sort out that little idle problem!

nice post keep up the good work

Yes I agree, I always wind the adjuster off before trying to remove, I think Dave got lucky not having too here.

Re: Replacing Rear discs/pads & adjusting handbrake on a classic

I replaced my rear discs shoes and pads the other day, all was fairly straight forward, upon driving afterwards I'm getting a light grinding in my rear drivers side wheel, to me sounds like drums/shoes rubbing, but the puzzling thing is only happens when turning left and has quietened down to how it first was, any advice would be appreciated

if your 100% sure they are all tight and not binding then its movement in your wheel bearing, its common on fronts but not as common on rears, but from what you have put it could be.
