    Front driver side brake binding!,

    Afternoon all,
    Changed out brake servo, bled brakes all round, now appears front driver side calliper is binding, any ideas anyone?.

    Ian, is the car pulling to one side when driving or just under braking or is one wheel getting hot?

      More details would help. Age of rubber brake hoses. does it bind when you drive. etc.

          Mal, I would remove the caliper and flexible hose, then the hose can be inspected, maybe replace anyway to rule it out, check free movement of the caliper piston etc, I assume these parts were not disturbed during the initial work.

            It was working, you bled the brakes and now it doesnt work.

            what would appear to have happened is that the fluid is forced under pressure to the caliper but cannot flow back under vacuum. therefore the caliper remains engaged, brakes on.

            not sure whether the pwda shuttle can block off one of the front brake pipes or not.

            I have seen very tired brake hoses collapse internally so that it allows fluid to travel under pressure in one direction but then collapse inwardly and act as a non return valve.

            sticking pistons in the caliper do the same but for different reasons.

            so to check I would.

            remove pads from affected piston, tricky if they are jammed on.
            connect bleed hose to nipple and crack it off. does fluid spurt out i.e. under pressure?
            with pads out can pistons be pushed back easily?
            if not crack open the bleed nipple and try again

            if pistons can be easily pushed back in with the bleed nipple open then fault will be the line between the caliper and the pwda

              And sorry to say if going that far
              just replace the lot as the worst bit is bleeding the brakes

                    Saga continues, bought new pair of callipers, don’t fit!!!, lug where top bolt goes thru too thick, not in mood for grinding or machining to correct size....

                    bought recon caliper, fitted that, changed pads both sides, still binding, me off to pub, car going in garage , patience and time run out
