Rear brake shield replacement
« on: 06 June 2019, 09:56:35 »

Iíve got a 94 omega 2,0 where the rear right brake shield is beyond help. The holes where the handbrake shoe pins go through are now roughly a centimeter in diameter due to rust. Also the whole area around there is falling apart. Looked on german eBay and found what seems to be aftermarket shields. Looks the same except the ring where the handbrake shoes rest against seems to be missing on the eBay ones. Are the brake shields two parts, or am i missing something? Car has the old type handbrake where the pins have crossheaded heads and the tip attaches to the back plate. Link to the eBay ones:

Your rear flange plates for the brakes were discontinued in about 1998 and superseded with the plates where the shoe pins are inserted from the back. The official way to replace your type of plate is to replace it with the newer version and you will also need:
24428129 gasket for rear brake carrier and
24445691 seal for rear brake carrier.

The seal goes in the rectangular slot, I think. Can't remember about the gasket. You will also need a new style brake shoe fitting kit 93174289 which is easily available.

The trouble is to obtain new flange plates of any description. They have been unavailable anywhere for several years. Including Cadillac dealers in the USA and Canada. And I'm not sure that any 3rd party supplier ever made them, for an Omega B.

We managed to fix an Omega B with your plates by tack welding the domed washers, for the pins, from a new style fitting kit onto the plate to repair the damage. Then re-fitting the shoes with the old style cross-head pins inserted from the front. However that won't work if there is not enough sound metal left. Repair outlasted the rest of the car and never failed the MOT.

To fit new flange plates you will also have to separate the driveshaft and rear wheel bearing.

There's not enough info in the German ebay link to be certain that they are the correct flange plates. It could be that they're from something else, perhaps a Carlton or Calibra and are similar enough to be used. Expensive but on balance looks like it's worth a punt. Send the flange back if it's not usable.

Pay by Paypal and you might be able to get your return shipping  costs refunded, you have to sign up for it with PP.

Thanks a lot for the information. I have already ordered the eBay one to see how it will work. Did use Paypal:) there is certainly not enough healthy material in the old one for an easy fix. That whole area is crumbling to pieces.

See here for Paypal return shipping refunds, hopefully it won't come to it.
