    hi, does anyone know if the front 4 piston calipers have slider pins or is it just the pistons ? the brakes are binding and when i brake hard they stick on and it doesnt want to move,happened 5 mins from home yesterday and by the time i got home they were smoking,,it freed itself up the next morning,,but was still binding abit and not rolling freely......any advice please.

    no there pushed against the discs,,the pads are always rubbing and getting warm,,when i brake (about half a press),,they bind on to the point where the car does'nt want to move,,and after a while (parked up) it becomes unstuck but are still rubbing,,,,like it eases off just enough to move..then feels like driving with flat tyres.

    hi mate I used to get this a bit on my brembos think it was just a build up of brake dust and crap. I used to take pads out good clean. clean all the pins clips and callipers dab of copper grease on back of pads to stop brake noise

    see if when you slide pads back in they slide in and out of calliper free. if not you may have to as I did file ends of pads

    lol I understand. but that could be what's causing the problem that the old pads are not free in the calliper so as you brake the pads are touching disc and not releasing so heat is building up and making pads stick on

    I made my own pistons out of stainless steel, got a refurb kit New seals etc and fit them at cams whilst Brian changed my discs, no more binding!

    cheers for the advice guys,, turns out the pistons were seized, 3 on the passenger side and 2 on the drivers side,,father in law managed to free them up and re-grease them,,but the seals were no good so its a temp fix to keep me mobile,,ill be getting a couple of new calipers asap as the backs of them were crumbling apart,,can anyone recommend a good brand......and thanks again for your advice.
