Subframe off is only a handful of bolts, and with a disc conversion, could make life a lot easier going forward ;)

Thought of that BUT Mini Me has just blown 150 quid on 2 new drums, bearings, set of shoes and a pair of new cylinders  :-\
OK, get these...

Out of interest is it rust that's stopping the drum from coming off or that there's a wear ridge in the drum that's stopping it clearing the shoes?Best rust buster I've found so far-without resorting to a gas axe-is a 50/50 mix of atf and acetone[nail varnish remover]mix it well and apply by brush/drip it on/trigger type spray.

You're replacing the drum aren't you?
Cut a couple of slots 180degrees apart with an angle grinder

Remove the subframe to make getting the drums off easier? What have you been drinking?

My first link showed a complete axle assembly with discs...  ;)

My second link is for brand new genuine stub axles for a tenner each... Twice as many bolts but possibly a simpler solution :y

Cant see why its not coming off, never even had this, do the drums rotate?

Its usually a case of pull the drum whilst hitting it at 3 then 9 o'clock and away them come.

Been working all day so just seen this lot ...................

Drum rotates on bearing.
Definitely not the pads catching on the drum.

Looking to me like some oppswit has windy gunned on the 32mm nut which secures the drum / bearing onto the spline and with the heat from the worn bearing, its seized onto the shaft.
The 3mm play I have is definitely the bearing breaking down in its cage.

Like the idea of angle grinding a couple of slots @ 3 / 9 o'clock and seeing if I can get a crowbar / couple of pry bars in there  :-\
If that doesn't work, i'll remove that side shock and pull the full unit off and work on it in the shed  :-\

All tomorrow unless I get dragged into work  ::)

If the worse comes to it, Mini Me will have to buy a backplate and abs sensor (if I knacker it) and i'll just rebuild the lot up with the new cylinder / shoes / drum and fit it as a complete unit

As always, thanks lads  :)

Bearing seized  :(
Any rust would have turned to powder with the amount of abuse it got yesterday  :y ;D

Well after more heat / abuse and burning out my last grinding disc i've just ordered this one off eBay for 11 quid delivered so that's on its way  :y

https://www.ebay.co.uk/itm/VAUXHALL-CORSA-C-00-06-O-S-OFFSIDE-REAR-BRAKE-DRUM-WITH-REAR-WHEEL-BEARING-ABS/263993331435?_trkparms=aid%3D888007%26algo%3DDISC.MBE%26ao%3D1%26asc%3D20140328180637%26meid%3D76e96f376861443690dab26bbb99dcac%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D332641060445%26itm%3D263993331435&_trksid=p2047675.c100009.m1982

I'll strip it, clean it up and rebuild it with new cylinder, shoes, nail kit, drum and bearing and bolt it back to the car.


I've been led to believe that the recommended torque value for this nut is 175nm  :-\
Can anybody confirm this please ?

Ello peeps  :D
Apologies for the delay in updating this but its silly season in retail and quite frankly, the cars hardly been touched  :(

Right, all the rear brakes have been totally rebuilt with new parts.
All put back together and the handbrake works perfectly but we still have major problems with what I can only describe as "No Pedal"

All the rear brakes have been drained of what little fluid was left and new Dot 4 pushed all the way through to the point of all we now get is virgin fluid and no bubbles but regardless of the engine running of not, I get no brakes (or pedal) until I have pumped the peddle down at least twice  :(
I have also bled the front callipers to the point of no air and steady fresh fluid there too.

Again the peddle is the same.  >:(
I have tried to actuate the abs pump using that code reader which shall never be mentioned by name with the reservoir cap off to see if I have a air lock in the pump but it made no difference  :(

Anybody have a clue what the problem is ?

Apologies in advance if I don't reply quickly. 
I very rarely get near the pc at the moment but I will answer asap  :)
