    Fronts just push back, rears need to be wound back.
    Its possible to do it using a g-clamp to hold preassure on the piston, then twist with a screwdriver though.

    What is the reason for screwing in the rears?
    I have done the fronts but still have the rears to do see.

    Rears are threaded as they act as a self adjuster for the handbrake.

    TBH, the best way to wind the pistons in is to use a brake piston winding tool... You should be able to get one for around £15 and will save you potential headache...

    Guys, is this easy to do? I'm not a complete numpty when it comes to mechanics, but I've never changes discs/pads myself before. Mine need doing soon so if I can do it myself I'd rather that than pay someone else to do it for me.

    Doc, I was a total n00b on this, but once a friend bobbed over to do my old Renault brakes, I realised how stupid I had been. Best thing to do is search for your specific car (forums, Google etc), read and have the guides on hand when you do them. They are almost as simple as unbolt, new stuff on, done.

    To be honest, it's the same with all mechanical and electrical bits and bobs, which is why I have the upmost respect for people, like Badger, who have gained so much knowledge over the years it must be almost leaking out of their ears!

    i changed my rear discs and pads last week. Dont mess about with screw drivers trying to wind the pistons back their probably be stiff and your end up not being able to complete the job without the piston winder. Top tip for getting the
    securing screw out the disc, use a slighty oversized philips screwdriver use a hammer to give it a few taps so its tight and snug it should free the screw without causing any damage to the screw head.

    Thanks guys, gives me more confidence to do it myself. I'm pretty mechanically minded & dare I say it not stupid (no responses needed on that point thanks!) but there's always that "what if...?" question in the back of my mind.
