    I'm about to remove the ABS from my MK3 VR6 track car and put in a F/R bias valve in to cure the rear lock up from coilovers.

    Going to replace the complete brake lines and need new unions.

    What are the brake union sizes I need to get?
    I belive they are 11mm, where the MK2's are 10mm.

    Anybody help or even done this?

    That's what I wanted to check.

    Does the Mk3 use M10 x1mm unions then?

    the caliper brake lines are m10x1 for mk2 and mk3, with 11mm spanner size. the master cylinder connections are larger on some though so you may have to do a bit of faffing to remove the abs. or just fit 22mm mc which has the right fittings on
