I am overhalling the brakes and have to replace the backing plates which are on order. there rottern.

How do i remove the rear hub to take the rear brake backing plate off Photos would be handy, I have all the tools needed but have not yet removed a rear wheel drive hub. I am a little stuck. Anyone help me please.


Thanks in advane for your help.

Excuse the typing my keyboards not working 100% of the time

You checked the Maintenance Guide section and found the following for rear brake overhall?

http://www.omegaowners.com/forum/YaBB.pl?num=1152564750

Once caliper and brake shoes are removed, the disc assembly is removed after undoing the large hub nut under the grease cap that you see in one of the pics.  Cant remember if there is a precise howtoo for the sh!t shield replacement though....

Well i have removed the rear driveshaft suprizingly easy however getting the back plate off is still a pain in the arse. if anyone has ever shanged the back plate Please tell me how to remve it my haynes manual has not arrived yet as it is on special order.

I guess the backplate wont pass over the hub??

iirc,  You have to undo a large nut behind the hub, where you unbolted the drive shaft. This lets you pull the driveshaft flange off which then releases the hub.
I will look up the procedure tonight. In the meantime search for posts about rear hub bearings.

If its just the holes for the brake shoe pins that have rusted out can you use a modified washer behind the brake plate or fit the pins from behind as the earlier models together with the slotted top-hat washers? (guess they used longer pins)

[Falcon_II]

It is both the holes and the plate the area that the Shoes mounted to was rottern through so I couldnt get the shoes to sit straight. i have just picked up the new ones for both sides so hopefully it will be much sharper stopping. I did have a problem with the pins as well but mannaged to get them sorted its the dual pot rear calipers and the pins supplied were 65mm the old ones were 75mm.

I have removed the nut and pulled the bit at the back off with a bearing puller. it came off after a bit of work with the windy gun and didnt damage the thread thank god.

but i snapped the end off my spline set so have to wait for the new set tommorow. I have not started on the other side but may take the camera out if its good weather tommorow. so i can create a how to thing for the forum.

its not the easiest job as the backing plate seems to bolt on under the outer hub and thats the bit i am stuck with, I cant see how it all fits together, thus cant take it apart. I am very good at working these things out I managed to get this far with out the dreaded manual. and I am not a qualified mechanic but can strip an engine and get it back together and working as well. LOL Sometimes. you dont want to look at the first head gasket I did. it only lasted 150 miles.

once its off I then have the fun of trying to put it all back I dont have a hydrolic press to make it all go together.

hoping the wood and a mallet will sort it out.

You are now supposed to attach a special tool to the back of the trailing arm (Unbolt the backplate first, then the tool screws into the threaded holes for the brake back plate) and press out the wheel flange.

I first thought of a slide hammer fastened to the wheel flange but that would likely damage the bearing track.
You might be able to make up a press, say a thick plate drilled to the backplate bolt pattern and a M12 bolt and nut through the middle, add a ball bearing to reduce the spanner loads. Or adapt a puller somehow.

Well finnaly got the bolt out . I made somthing up to try and pull the bearing out from the font using a solid brake disk and a bolt with a 32mm impact socket on the rear and a bolt inside that. it pulled the bearing 2mm then the brake disk shattered, so did the other 3 i had lying around, its well stuck and now both bearing cages have shattered. I need a 70mm disk made of steel about 1/2 inch and a bar made of about the same thickness, drill 3 holes into the bar one to go through to the back side of the bearing and two to make legs out of other bolts. then I am going to have to hope that the bolts have enough force to pull the bearing out.

What a pin in the bumb. I still havent thought about starting the other side but it has to at least have the rear hub bolt removed as i have to take the windy gun back in the morning.  Mine just wasnt hard enough.

 Slide hammer had no effect. and just ripped the end off the slide PITA pain in the "Guess the last word"

I hope the other side works better, is starting to cost me some cash now.

£150 car
£40 MOT though I should replace the brakes as effort was a little low.
£90 Exhaust back box plus 2 centers
£55 for 2 rear disks 4 Shoes and 4 Pads, Plus the new pins and Fitting kit.
£60 for the new rear bearings
£40 for the new backing plates
£8 for the pins clips etc from vauxhall as there different to the older 1995 type
£12 for 8 new bolts 1.2mm thread with round heads and allan keys
£20 for a new spline bolt Pro set old one snapped removing the above bolts.
£11 Haynes Manual, and its useless for the job i have to do.
£? for the front disks and pads

Think thats £486 and I havent even taxed it yet, or started the front brakes or even had time to play at driving it.

So can i just check please, did you have to replace the brake pipes or was the mot guy trying to shaft me??
I am only asking cause at the same time we had the mot done, tina gave him a 40/17 tyre to swap and he reckoned it split as they are very delicate and he bent the rim ? yet another tyre place turned one around in 10 mins , so if you DIDNT need to do the pipes i think i will go and pay him a visit
Sorry it has cost you so much i honestly didnt know!

No full front to rear pipes have already been done and the front pipes needed doing.  The cats were good but a pain to do.

I managed to get the brakes working Okay with new pipes and ajustment. but they were real close to metal and the disks were just passable, thats why i decided to change the diska and pads all round. but its being a pain. you would have had a garage bill of 2-300 just for the labour replacing the brakes and the price you would have had to pay for the disks would be around the £20 -30 each mark.

If you want to buy it back after im finnished it may be up for sale. I have found my cash a bit short since i bought it.

The 406 I was driving round in blew its fuel pump after I bought your car and its not a small job engine timing belt needs to come off etc. the pump is part of the engine. so the scrapyards wont allow it to be taken off.

WellHad to get some new bolts and do some hellish bearing moving to get the old one out. Then the fun of moving the new one back again. 2 hours later and a few cursed words and one side now has New Back plates Discs Pads and Shoes all I need to do now is re make the brake lines Bleed them AGAIN. oh then start to get the other side done. PHEW.

Happy Xmas to you all and a Merry New Year
