brake distribution block sticking?
seals blown?
pedal return spring broken?
pedal-master cylinder pin broken?
wrong fluid?
Flexies swollen?

if the rubber has swollen sufficiently to close the centre hole - the pressure may get past, but as soon as you release the pressure the hole closes again to restrict the return back to the master cylinder. unlikely, but not impossible.
Makes sense, car been stood for two years and its a 'V' reg Saxo
Rears dont seem to be affected, was thinking it might be the link bar that links brake pedal to servo which is on the near side but that would affect rears as well I spose as they are adjusted up to the drums and no play.
thanks for the tip.

I would open the caliper ,pump out the piston .Peel back the rubber gaiter ,check for rust,crud or corrosion . Clean with a rub of wire wool .
Or your pipes could be knackered as daft reckons .

Thanks but put two new calipers on and they are both sticking so got to be a hydraulic problem I think.

not got a crushed brake pipe?
tried releasing the built up pressure on each caliper when front jacked up,
undo bleed nipple on each side a tad,
both wheels of,
to see if calipers release a bit?
if pressure IS in system, not calipers??
but put big foot pressure on calipers with nipple undone a bit to see if peddle goes down?
then tighten nipples to see if calipers hold pressure again if the had released.
dunno, but thats the way I`d go..

AH, not wrong calipers, holding one pad so tight theres no room for free play?
try putting worn pads back in to see if it still sticks?
had that prob years ago on a motor,
someone had put a non vented caliper on car one side,
was just too small for vented discs and new pads.
so I put 2 "good" pads in it

New calipers exactly the same as old ones as are the pads. pedal goes to floor when nipples opened. After standing on pedal brakes release slowly takes about 15 mins or so

ok, accumalation of crap in master cylinder?
not abs?
suck eggs question but did the brake fluid come out clean when bleeding?
if pedal goes to floor when nipples are undone @ calipers, then the fluid flows freely?
got me stumped now

Non ABS, bled all fluid through so new stuff, can only be flexi pipes master cylinder or servo.
Problem only slight at first, mentioned on MOT sheet but not noticable whilst driving.
Got worse with use
Just had a call from my brother who is driving the car with binding brakes and he says the problem is intermitant.
Says he just got home after driving normally and the brakes were free and cool wheras on the outward journey this morning the brakes were smoking when he got to his destination.
Might be bits in the master cylinder I'm thinking but dont realy know.

I'm thinking servo. Maybe it's 'sucking' the brakes on even when the pedal is not depressed, just a little so as to overcome the resistance of the return springs etc. We had this trouble with a remote servo on our old Series 2 back in the 1980s. On dismantling it we discovered that it was full of brake fluid. That's where all our diligent topping up over the previous two years had got to.

It doesn't have to be leaking fluid into the servo - that was just to give you an idea of how knackered ours was. The point is that the servo might be exerting a little pressure on the brakes even when the pedal isn't depressed. The key question is whether the brakes appear to be binding with the engine off, or with the vacuum pipe disconnected? I'm not familiar with this particular car, but another thing I'd be interesred in is springs. Springs to return the pedal, springs to return the plunger(s) in the master cylinder, springs to push the friction material away from the discs or drums. Are they all in place and not tired, rusted through or otherwise hors de combat?
Brakes ok, rears cleaned and serviced, adjusters working ok.
Fronts have new calipers, discs and pads, all correct items.
Pedal seems free and returning
Not sticking every time, going to check it out tomorrow when I get it to fit the new cylinder and lamba thingy.
Picked up car today and drove it back to workshop. Had to stop half way because tha front brakes were red hot and smoking.
Released some fluid from the calipers via the bleed nipples and all was well, continued the journey using the handbrake.
There was a lot of vacuum holding the master cylinder on to the servo and the was a rush of air when I removed it.
Fitted new master cylinder and tried the brakes in the workshop, couldn't get them to stick on but engine not running.
Returned car to my brother, tried brakes as I set off and they didn't stick on.
Got to where my brother works and the brakes were smoking again, sticking on but just the fronts.
Decided to remove the vacuum pipe from the servo and see what happened, brakes didn't stick on.
He is going to use it for work with the pipe off for a couple of days and see how it goes but it looks like a servo problem as Brown suggested.
Must be a filter on the servo somewhere maybe its blocked or just servo knackered with being stood for so long.
