has anyone else had a problem with a sticky brake pedal not returning fully
and leaving the brakes on slightly?
this is the only main problem for my cars mot

Iv just had a seized caliper which basically jammed the brakes on the front n/s wheel. I managed to release it though when replacing the discs and pads.

Have you got a rear load limiter from the brake pipes to tbe axle? Ive have these sieze before making me think it was the master cylinder as it had the same symptoms, make sire you can move the lever on it, if its not that i would put my money on the master,

even worth check the flexi pipes as ive hsd these collapse inside before causing the pedal not to return by itself

will check but its making a squeeking noise from servo area
