    Ive got an 8v shell mk2 and I need new brakes. What’s the easiest way of finding out which brakes I need for it?

    My mate has some brand new ones he’s doing a deal for me

    Tbh, 8v brakes are weak, the best investment is a set of 16v or g60 front hubs and discs with matching calipers.
    But if you stay with original stuff, it's a 239mm disc. Vented.

    Cheers for the advice. The issue is what size brakes I need, I’ve heard the 16v don’t fit on the 8v.

    On my road CITI i'm currently keeping with the 239mm GTI discs.
    I'm on set 4 of pads
    Now on expensive race type carbon metallic pads, which work. From nearly cold
    Fast road? Tried them, waste of time

    have a look at your wheel bearing carriers and your calipers. If the brake carriers are cast into the bearing carriers, you have the 239mm versions. For 256-280mm you need the type which has 2 bolt holes cast into the bearing carrier for the caliper carrier to bolt onto, like this:

    For 239mm setup on the caliper itself if it has 'VWII' cast into it then these are for the thicker 12mm solid discs and vented 20mm discs (GTI should have vented discs) if no markings they are VWI and only work with thinner 10mm solid discs

    VWI:

    They don't. Thats why I said 239 for standard, 256/280 for uprated.
    RJs pic should help. on an original 8v the caliper carrier is part of the hub.

    Can anyone point me in the right direction for discs and pads?

    Thanks

    k'inell, is that disc thin or what on the outside :lol:

    yeah so standard GTI 8v brakes 239mm vented. have a good check over while its in bits, make sure nothing is seized etc as you've nearly worn the disc thru to the vents on the outside but nowhere near as much on the inside

    Those 'metallic' pads are sure hard on the discs!

    So the brakes are on but one of the callipers are seizing pretty bad. I'm replacing them but on VW Heritage there are two different calliper sizes. I've got 239mm brake discs but the callipers say they fit "239mm x 12mm and 239mm x 20mm" and "239mm x 10mm"

    Not knowing the size of the discs I bought as they didn't have that info can I get the "239mm x 12mm and 239mm x 20mm" calipers?

    Yet another question about brakes... sorry if this is obvious but I need rear calipers too. There are a couple choices on vw heritage and just want to make sure I get the right ones. Does anyone know which calipers I’ll need for an 8v mk2

    Thanks

    pre-88 you will have 36mm piston rear calipers, these have the handbrake cable on the top and hard line underneath. post-88 they're 38mm type with handbrake cable on the bottom and hardline to the top. if you have later setup you can use mk3 golf calipers which have a redesigned handbreak mechanism which is a little less prone to failure :)

    you can fit late type calieprs to an early car if you fit them upside down, also mk4 golf calipers are an option but you also need a set of flexi adaptor lines. no real advantage of using mk4 over mk3 except they're lighter as alloy, they still corrode & seize plus bleed nipples are prone to seizing in due to differing metal corrosion

    those are pre-88 type, 36mm piston. have a look at where your handbrake cable is attached, easiest way to see which you need
