Front brakes locking on

I?ve experienced that my front brakes can lock for a little while after braking. They always lets go after a short while. To solve this problem I?ve recently fixed the front calipers with all new parts. However, the problem remains. Any suggestions what this might be?
Best regards

Hi
I agree, its the servo. A friend up the road (who is probably reading this) has that problem on his car. Not badly but enough to make braking really disconcerting. He lives with it. I couldn't.

Zetec+ 2 under const, also 130S. And another 130S for complete restoration. Previously Racing green +2s with green tints. Yellow +2 and a couple of others, all missed. Great to be back 04/11/2021 although its all starting to get a bit out of control.

Hello, not to get nit picky but when you write all new parts, are you meaning new front calipers? If yes then it may be the servos but are you sure the pedal is not sticking or hanging up? Do the wheels feel hot to the touch after driving? I'm thinking sticking pistons in the calipers if the whole unit has not been replaced...

Hello again, I'm a bit confused, servo sticking? Is that the power brake vacuum unit? What can stick in those? I'm thinking the piston in the caliper may be the problem. We all love one another but even the English langauge has nuance(s)...

64S1 brings up a good point (pedal sticking) you do have some "free play" in the master cylinder push rod? if not a pressure build up can occur when the brakes get hot, would also free off as they cooled.

Hi,
yes the "power brake vacuum unit"...
the Lockheed version of this unit that is often fitted as a replacement to the Girling one can stick on momentarily as you move off from stationary. It is a known fault that can be rectified by repositioning the unit or by puting a spring into the white projection on the side of the unit..
Cheers

My problem was solved by talking to another guy on the list (John Clegg) a couple of years ago. He mentioned that there is a service amendment or something from Lockheed noting that carefully attention had to be given to the siting of the servo with respect to the orientation of the white valve that sits on the side. Unfortunately I cannot remember the exact advice, but I am sure if you contact him he'll know. The other solution was to insert a wire spring(about 2cm wide and 2cm high) into the valve pressing down on it. John was kind enough to send me one he had spare (for which I owe him a beer!) and it solved the problem immediately.
Hope this helps
