Rear brake troubles, Why do they keep locking ? Options

[Thor]

Hello to everyone at 914world.com. I am a new member from Belgium and ready to post my first question ...

Fase 1: Summer of 2003 ... during a saturday afternoon trip, I suddenly felt that when rolling to a stop the car balanced diagonnaly. At a stop I got a burning smell going through my nose and soon discovered the rear left break was smoking and running terribly hot. I got the car home and my mechanic unlocked the brake.

Fase 2: While passing the annual technical control, the mechanic said there was still an imbalance between the rear brakes. So back to the shop (another - VW-Audi based) where I was told the brake pads were gone and they replaced them.

Fase 3: During an orientation rallye in november 2004 the rear brakes started to squeal and the burning smell was back. This time the right rear brake started to lock. A quick repair in a garage where some young mechanics wanted to have a look at it put us back on the road. We had some good moments but at some stops the right brake would still feel hotter then it's supposed to be.

Anyone an idea of what could be wrong ? Calipers are supposed to be replaced before I purchased the car.
What can I do to restore the balance and keep them from locking ?

Thanks guy's ! (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

My guess is those two things (new lines and venting clearance) will solve the mystery. If not... rebuild.

Your guess is my hope, Eric !
Great explanation, now I've got something to work with !

If you have drilled rotors they may be "irregular"

They're still in the box, brandnew. I'm gathering all bits and pieces. If you look at my reply to the members pictures section you'll know what I mean ...

I would replace with factory rubber lines

What would be the difference with the braided ones ? After a reply like this I would allmost immediatelly go for the originals, but I just want to know.
