Please Help Storm With Stripping Rear Brakes
« on: August 14, 2009, 21:09:48 PM »
Grr, just went to move my g'f's ecotec out of the drive. Put it in reverse gear, took the handbrake off, and reversed out no problem. Then put it in 1st gear, went to pull away, when there was suddenly a dull 'clunk' noise from underneath somewhere, and it now feels as if the handbrake/brake has jammed on or something, and i can hardly move the car.

Symptoms are:

* Handbrake still engages/disengages normally. When applied i can't move the car at all. Dont think its that.
* I can still engage all gears, doesn't feel like a gearbox problem. When i engage 1st and give it lots of revs it will just about move forward, but feels like when you leave the handbrake on and try and pull away. ie it's straining.
* Brake pedal still seems normal when applied and pumped.
* There is no EML or brake warning lights when starting up.
* Car has been driving and braking normally with no sign of any problem, until this suddenly happened.

Basically it just feels like the handbrake is on, even though it isn't. Am guessing something has happened with the brakes, but what would cause it to suddenly apply the brake(s) by itself?

Can anyone suggest a likely cause based on the desription? Or give me an idea of what to check?

My first thought is jack the car up and spin each wheel to see which one (assuming it is only one) has stuck? Just off to do that now.

Any help/advice gratefully received!

Sounds like your brake shoes hav broke away from the rear backing plate. Jack the car up one side at a time and try turn the wheel. If jammed you have found the side at fault.

Sounds like the pin has broke that goes through the backplate and jammed it up.
Very common on carltons and I would imagine similar on the Cally

Happened on my old redtop. thing is.. you'll need to take the brake discs off to see. and its most likely a rotten back plate. Ask Dan :) not the easiest job to change :(

Nips. One of the studs is a 19mm rather than the usual 17mm. The only socket wrench i got here in the new house is a short stubby one, that's blatantly gonna bust if i try and use that lol.

Just off round me dad's to get a heavy duty wrench!!

Not really done anything with brakes before. Anyone got a pic of where the pin is located that might be broken? Are the pads easy to get off?

While the wheel is off, have a look at the backing plate from the rear. You should be able to see the locating hole that the mounting pins push through and turn to lock in to. These rot and round off. Normaly you can see one of them, but the other is hidden. To see the full extent within the drum is a caliper off job, then remove the disc. Not a thing to do in the dark if need so.

Auto Vaux parts on line sell the backing plates but a pig of a job to replace. However there are short cuts on how to do it, and other members know the way to do it on here. cutting the backing plate if you wish to replace the complete item (best way i would say).

Ok got the wheel off. Had a good look from all angles and can't see anything obviously wrong, other than the caliper is clamped firmly onto the wheel.

Here's some pics i just took below. Not sure what I should be doing next though. Need a step by step please.

...or if this is going to be a sod of a job, should i take it to a garage?

No. The brake is jammed on.

G/f said earlier that it had been squealing today which it hadn't done before. May have a sign of impending failure.

is this a sign of not tuning up on sunday?

Well it was looking good this morning, but it aint looking good now. Am gonna work on it all day tomorrow but cant see me fixing it for Sunday, not unless i can temp repair it somehow.

right, get a strong tourch and shine it through the inspection whole in the disc at the top but about one inch from the top (inside) you will see a adjuster, get a screwdriver and turn the cog until the handbrake frees up

soz if none of this makes sence, ive been down the blue boar on the tequila (haha had to goole how to spell it lol)

I'll have a look and see what happens.

This may be a stupid question, but how do i tell if it actually is the handbrake that is the problem, or the pin mentioned above, or the wheel bearing?
