    7mm
    use a woodwork type g clamp to carefully wind the pistons back, make sure
    that the master cylinder does not overflow.

    Hi, thanks for reading,

    I want to change front brake pads tomorrow. Cos I am skint I need to find
    out what size hex key wrench I need so I can remove the caliper retaining
    pins.
    I shouldn't anything else should I ? or maybe an open ended spanner for the
    retaining pins ? if so what size.

    The vehicle is 1989 1.8i audi 80e.

    Are there any tips on getting the piston pushed back easily, so I can get
    the new pads in?

    Thanks very much again.

    & it's a lot easier with a socket mounted allen bit than an allen key.

    Well opening the nipple gets that nasty coloured fluid out the caliper.

    The factory recommendation is to let the fluid out at the caliper, however,
    most people seem to have difficulty with bleed nipples, so I usually say to
    push the fluid back. Also there is less risk of air getting in by pushing
    the fluid back to the master cylinder
