    Hi out there,

    Just had to change my rear wheel and notice that the disc was a little rusty. It look like the caliper may have seized (its a Bosch one). If you remove them can they be freed off if so how do you take them off? Or is it a new caliper? If so can they be changed individualy or do they have to be done as a pair?

    Just want to try and save a lillte cash or have the info ready for when I have to take the car to a garage.

    Many thanks

    Fatgaz

    Calipers can be changed individually, though pads can't. The problem with changing just one though is that the new one will probably be working more effectively then the other old one & you'll have unequal braking (never good). Plus, the other caliper will probably been in a similar state to the one you replaced & seize itself in the near future.

    A good mechanic would be able to save you replacing either by servicing or overhauling the calipers if they're not "too" bad. Get them to check the fronts too as they carry 60%+ of the braking force.

    use a hose clamp or two sockets over some mole grips to clamp the hose whilst you remove the caliper, then just strip it down, clean it all up, replace seals (£15), refit, refill, release and bleed. No problem!

    If you're going to take calipers apart, make sure the outside is VERY clean before you start messing around trying to take pistons out & fitting new seals, as any dirt in the caliper cylinder could damage the seals & that could be worse than a seized one as you'll have no brakes at all.

    Plus, you'll have to free the piston whilst it's still on the car; take the pads out, get a big screwdriver between the piston & disk then get someone to press the brake pedal fairly gently whilst you keep the piston from coming out all the way. Once it's a bit free, stop brake pedal pressure & push the piston back in, do this a few times & that could solve the problem anyway. Remember to use fresh fluid to lubricate the seals if you do take the caliper apart and copperslip when you reassemble the the caliper.
