Default Rear brakes refurbished

Hi.
The work on the 75 continues the today with the rear brakes.
I couple of weeks back when I hit the brakes approaching a roundabout ,I heard an horrendous grinding noise from the offside rear brake.Even after taking my foot off the peddle it continued to grind.I stopped immediately and had a good look around but couldn't find anything obvious wrong.Since then though the rear brake has making a slight thumping noise when the peddle was depressed.Some day's it would be much worse than others.
As I've got a few days off over Christmas where I won't need the car for work ,it was time to have a good look a round and get them sorted out.
The pads and discs were in reasonable condition but the shoes used for the handbrake were not so Great. My car is an automatic and for my sins I've rarely use the handbrake over the 10 years of ownership (yes I know I should).
So being curious to know why the shoes had worn so badly on the outside, it turns out that a assembly that holds the brake shoes has rusted away setting the shoes free.So today it's an expensive day of replacement of both discs and pads (might as well do it whilst it's all apart) new handbrake shoes and the backing assembly (don't know what the proper name is) on both sides.

Hello John,
You've reminded me of the old adage -
Use it or lose it.
- which I've found so true about almost everything nowadays.
The backplates and associated bits and pieces are available as a kit from DMGRS here: https://www.dmgrs.co.uk/collections/...0290-smn000140
Good luck with the job. If you need any advice, you'll find plenty of help and HowTos around the forum.
TC

Give yourself plenty of time to do it, it looks and is a reasonably simple job to do and if all goes well doesn't take too long



Some the things to watch out for are:


1) Be careful not to damage the wheel sensor.


2) The four bolts holding the backplates on can suffer from a combination of a couple of things the first is that the heads can rust to a circle and the threads can rust in.


3)The handbrake cable outer ferrule, where it fits into the backplate tube can rust solid and be a so and so to shift.


4) Take a photo of the assembly for reference if needed.


5) Be sure to torque the hub nuts correctly and re-stake them.


A little tip ref the nuts, if you re-use them you may find that when tight, the area where it was previously staked still lines up with the slot and due to the distorted metal won't give a good stake, the solution is to swap them over, O/S for N/S and vice versa, this usually gives a fresh area of metal to stake.



There are good how to threads on here, have a quick look at them.

I struggled with the caliper mounting bolts and eventually bought a 6 point 13mm ring spanner which did the job!

I bought a set of 6 point impact sockets which are brilliant for stubborn fixings. I don't necessarily use them on an impact gun. My regular sockets get very little use these days! I'm going to make up a flat and a cranked piece of flat bar with a 1/2" square drive attached for those tight spots where you can't get the ratchet in.

I second what has been said above. Its a good idea to have fresh caliper and backplate bolts ready. When I did mine last summer some of the backplate bolts were extremely tight to get out, but did thankfully. I knock the handbrake cable guide off the backplate and then use a.small cutting disc to carefully go through it lengthways.
