Default Re: rear O/S brake locking on.

One method is to get both back wheels off ground safely, draw lever up 3 or 4 clicks and adjust until the wheels are gripped both sides, and spin freely when the handbrake is released.

What will often happen with old calipers is both wheels wont grip at the same point, but if everythings right with the slide pins and new or recon calipers, and both cables are fine, then it should take up evenly.

When off you should see both levers on the rear calipers fully return to their stops, and the rubber boots on the cables intact. The boots can split and water and corrosion can enter the bowden cables sticking them, or the return springs weaken, but again the springs should be fine on new or recon calipers.

Will take this advice on board. It was given in good faith and have used it for years.

Off to buy some white ceramic grease/high temp silicone grease/red rubber grease.

ok,

seems that the problem is to do with the handbrake... wheel runs fine then if i apply the handbrake it locks on and the cable doesn't return hence it staying tight to the pads.

anyone else had this problem???

cheers people.

20 - 30 yers ago it was considered good practice but time and knowledge move on, some people havent I used to use it long ago myself

I recently used ceratec on some lucas rears on my brothers astra, its been fine since. Cleaned a load of blackened grease and old copper grease out of the pins.

Is the lever returning to its stop as I previously mentioned???

As I said in my previous post.

Weak return spring.
Bad handbrake cable due to corrosion or dirt ingress.

Could also be :

Knackered internal drive thread inside the caliper if you didnt use a wind back tool to compress the piston.
Sticking piston due to damaged or displaced seal.
