    i'd be second to take note of this tutorial as i feel i could do it, but the little pitfalls are handy to know in case it goes tits up.

    My garage pal wants to charge me £20 per wheel to fit them

    the brakes on a mk4 are slightly different to that. There are 2 torx bits in the back of the caliper under plastic dust caps (you cant miss them as they stick out for miles). Undo them and get a hamer out and whack the caliper up and off. The pads and everything comes out with it. Then to get the disk off theres just one little screw to take out and it should come off. Again depending on how long theyve been on you might need to show it some love with a hammer to get it off.

    Make sure when the caliper comes off you cable tie it up so no weight is on the brake hose and put some copper grease on the back of the pads to stop the squeeking. On mine i had to drill the little screw on the disk out to get the old ones off. It doesnt need the screw as the wheel bolts hold the disk in place, the only point of it is to stop the disk spinning when the wheel is off.
    It would definitely go better with an engine in it

    Just done this about 20minutes ago,

    1: Jack up the car and take the wheel off.

    2: Remove the brake fluid reservoir cap so you can keep an eye on the level.

    3: Use a large flat blade screwdriver and slowly prise the inner pad back so it pushes the piston back in as far as it will go. Keep an eye on the fluid level and remove some if need be.

    4: To remove the calliper undo the 2 18mm bolts (On the inside nearest the engine) that hold the calliper and carrier on and swing it out the way.

    5: Undo the alan key or Torx bolt that holds the disc on (Not sure what size and both types are fitted to different cars).

    6: Remove the disc. If its tight bash it from behind with a hammer, turn the disc 180 degrees and bash again. Keep doing it till it comes off.

    Assembly is reverse of removal

    Took me about an hour in total to do the fronts and Laura paint all the callipers.

    Ours were off ebay for £45 delivered for discs and pads (Just standard 280mm ones).

    Feel loads better than the old ones

    When changing the rear pads the piston needs to be rotated while pushing it in. Can this be done by hand or do i need a tool for it?

    Ideally you need a tool (Not that expensive) or do it with a clamp and pair of mole grips.
