99' Focus Rear Disc Brakes

[Joekayaker]

Hi guys,

Right I need some help please. A couple of weeks ago I replaced the rear discs and pads on my V reg focus estate. Trouble is, once installed and all put back together the brakes aren't 'backing off' enough and are rubbing on the discs. I drove around town a bit shortly after this and this causes the discs to get pretty hot even with no heavy braking. I had this before last year with a front brake and it overheated badly and ended up having to get a new caliper but the disc is slightly warped I think. On this occasion I've tried a few things such as pumping the cylinder out and winding back in a few times to try and free up any stiffness but this didn't work, I've also tried releasing brake fluid at the caliper to see if the lines are staying pressurised for some reason. None of this worked. Today I've replaced the caliper on one side, bled the brakes etc and now the same thing!!! The pads are still rubbing on the disc. And I'm sure it will overheat on a motorway run..

Has anyone got any suggestions please? Any help much appreciated.

Cheers Joe

have you adjusted the handbrake to accommodate the new pads?

[Joekayaker]

Hi, yes it does it even when the handbrake cable is not hooked on...

thanks, Joe

have you tried flushing the brake line without a caliper on it?

Hi check the flexi hoses havent collasped as i had this problem with a mondeo once, the pressure of the foot brake would push fluid past but it would not return. Dave

Not tried that. You think the pipes ma be blocked with rust?

Hi, they look fine. Also tried letting off some fluid which doesn't make any difference so I don't think it's a residual pressure issue..

Thanks, Joe

Adjusted the brakes manually after youve removed the calipers?
