Rear Calipers

[fishnchipsx2]

I've been able to hear a wheel-bearing whine from the rear-right wheel for a while.  I went to nip it up a little, but it had already been done up so tight that the split-pin didn't actually sit in any of the recess in the castle nut - so, I bought a pair of rear wheel-bearing kits today.

However, on disassembling the whole lot, I discovered that my rear discs are f**ked:



That's on the inner side of the right disc - as you can see, there is just one narrow band or shinyness.

Also, the pads aren't exactly in great shape - very uneven wear, and I only changed these a few thousand miles ago.



Now, does this mean that I need new rear calipers, or is will cleaning them up sort this out?  The rear discs are still nice and thick, so can I keep these without replacing with new items? 

If I do need new calipers: Do I have the pre-88 or post-88 items?  (My car is E-reg 1988!)  Looks to me like they have the external handbrake mechanism... does this mean that if I buy mk3 calipers, I'll need new cables too?



I don't want to stick the new bearings into a pair of discs which are f**ked, so a quick response would be greatly appreciated!

Cheers,
Calum.

A machining shop can re-surface the disks for you.

Are your handbrake cables above or below the calliper?

[fishnchipsx2]

Handbrake cables and bleed nipples are on top of the caliper, the brake lines are underneath the caliper.

Oh, and how much cash should I be looking at for a re-surface? 

My main concern is if I resurface the discs and put everything back together with new bearings, won't the same happen again?  The MOT is due in a month or 2, so don't want to have to do everything twice...

Infact - the first photo makes the discs look cracked - or is that just the surface?

For the sake of about £20 per side, I'd just replace them, with a new set of pads too. And whilst your at it - if you have ready access to some MK3 callipers - I'd put them on too. Going rate is £15 a side in a scrappy.

yeh i'd dash the lot in the bin even though the pads look fine.

Cheap enough.

Your calipers may be sticking. I had a similar problem with mk3 calipers. The disks and pads looked like yours

junk the lot

Gave everything a good look-over, and it looks to me like the calipers may not be pulling evenly due to play in the slider bolts?

Will get down a scrappy today hopefully to find some mk3 calipers, as I'm supposed to be moving from sunny Bournemouth to Leeds on Wednesday!

Will I need handbrake cables too?

[fishnchipsx2]

Right,
I managed to get a lift to the scrappies, where I acquired for myself a pair of mk3 calipers.  Also got some pads and longer handbrake cables from GSF.

A neighbour from a few doors down wandered over for a nosy, and it turns out he has access to a workshop, even tho he doesn't work there anymore.  I gave him my discs, and by the time I returned from the scrappies, he was back with them shiny as new - what a legend! 

I reckon if I mount the calipers upside down, the cables should still reach? I'm working against a time limit here, as I need to pack my things and move out on Wednesday morning, so not having to change handbrake cables should help a lot!

Priorities first tho, I'm off to the pub and then to get trashed in B-town, I'll reply tomoro to let you know how I'm getting on (with my hangover!)

I would still fit new disks, skimming them could be ok but to fit them and find they are wrapped means doing the job twice.
