Anyone know if the backing plates are available for back brakes?
Mine have corroded so badly the handbrake shoe retaining spring pins have pulled through so i've currently no handbrake.
TIA :y
-
Replacing them requires removing the hubs, so you might want to consider insitu repairs. Like aralditing washers in place.
-
Yea I had to get both last year. Cant remember part numbers but they not cheap

I got a old sheet of suitable steel (I used an old front brake shield) and made a plate, approximately this shape
(http://i297.photobucket.com/albums/mm240/leflemmy/rear-brakwe-2_zpsjokvgooi.jpg)
Which fits snugly and doesn't move, given it sits inside a flared section, also the tension of the anti rattle springs pulls it tight. It's a bodge, but a sort of 'professional bodge'. Fully intend on replacing the rear hub and in doing replacing the backplate for new/good as new one, I'll be stripping and repainting the rear axle this summer. Might get a mate to weld on a shaped washer or something as well on the new backplate to avoid it happening again.
If you're already not aware, Vx changed the design, as earlier cars have a slotted hole, the MFL onwards get a straightforward hole, with a washer, with slot inside, which is a superiordesign, as the hole can rot all it likes, as can the washer, when the washer corrodes, simply replace. Easier than replacing the backplate every ten years or so :y
The image on the right shows what kind of hole was torn into the backplate as the pin dragged and ripped the thin, rusty metal. That happenend on the way to the MoT, as well. Nice timing! ::)

Thanks guys think an in situ repair sounds like a plan.
I know what you mean geezer i think it was the mot handbrake test that ripped it out as it gripped. went through ok but the following day had a grinding on reverse which turned out to be the shoe locking up as it shifted slightly and the spring was mangled.
May consider welding an M4 bolt and washer into the back plate and use a nylock nut to hold the springs cap in place.
All good fun......NOT!!

I would like to say it's not bad, but to be honest it's an ar5e! Not as such the job, but the thirty different methods which you could use to hold it all together. I should mention that due to rust on the rearmost shoe, I have actually drilled through the cast metal plate behind the thin brake backing plate, and used a suitable long machine screw, filed and shaped washer and nut adjusted to the right length as a makeshift pin. The front uses the 'standard' setup, excluding the added backing plate, as illustrated.
It's one of those 'what works best for you' situations, really :)

Good grief! We now have omegas on the road with the braking system held together with sticky-backed plastic. ;D
I suppose all of this is fine for day to day footling but, if you had to perform an emergency stop........well, I wouldn't like the thought of a botched up backplate folding itself in half.
-
Only if you like to do your emergency stops using the handbrake :)
Fo pease of mind, my front calipers have been striped down, repainted, fitted with new seals, new GM pads and discs and when rebuilt fitted with mega-low mileage slide pins and a fresh coat of paint; just incase youre worried that one day you'll be heading towards me on a wet road :D

The structural integrity of the piece of steel has been compromised. If it's rusted away in parts, then it's bound to be much weaker as a whole. Although an mot tester might pass your car because the brakes work, I doubt he would be pleased with the stitching in of different pieces of metal.
Just my opinion.
I realise that, to replace the backplate for a new one, you would have to do a fair bit of work, but that's what I would do (or pay someone else to do it).
-
I reckon DBG's steel plate, stuck on the back of the rusty old back plate, is an excellent proposal. It will be stronger than the original, if stainless plate it would outlast the car. The steady springs carry no load save the spring tension, so the repair has no safety consequences. I imagine the cost of having both back plates replaced professionally would exceed the value of the car

Having new spark plugs fitted would exceed the value of the car. ;D

The wheel flanges prevent the backplates from coming off so you need to disconnect the drive shafts, pull the flanges off the splines on the inner end of the axles and then pull the axles out of the wheel bearings. What could possibly go wrong ::)

Piece o piss. Unscrew the half shaft retaining plate, screw a puller on and let fly. ;D

Nice to see that you are still of, sound mind, to be able to offer advice, of a technical nature........ :y :y

Merci :y
Also as I mentioned, I fully intending on stripping my back axle down for a proper repair, and repaint, refurb of all the components while I'm at it. Were the design of the backplate such that would allow it to be removed without the removal of the hub, I'd have changed it for a new one that afternoon. Sadly I had to go down the bodge route, but made it the best bodge I could. :)
Might be I get a low mileage back axle cheap and just refurb that one, might be simpler, and less room for costly mistakes. (At least if I bugger it up my cars not off the road)

Exactly. And when you've done it, you can win the lottery buy walking into a shop and buying a ticket ;D

If only we could use a line lock on the footbrake and do away with the handbrake shoes........... oooo now theres a plan lol.
-
Except cars with hand brakes that operate the rear shoes have been known to roll off down hills when the brakes cool :-X ;)
The shoes are the best option, although a pita to work with.
And my 2p... Sounds like a perfectly acceptable fix. STMO clearly doesn't know what he's talking about as the rear backing plate has no connection whatsoever to the foot brake system and its only braking link is the handbrake. The backing plate and hand brake shoe mounting is now stronger than it was ;)
