Title: 312mm brake conversion
Post by: Dan_GTi8v on 28 April 2012, 18:38
Been reading up on this and learned I need 312mm discs and caliper carriers, and use my standard 288mm calipers and pads.

my question is will the 312mm calipers not fit or do people keep the 288mm to save money?#

also what are the standard size rear calipers on the mk3 GTi? and is there any conversion I can do to make them bigger as well?

cheers

Calipers from 312 will fit, its the carriers that differ, and you need to run spacers to make em fit, you should read my dub ride thread as iv recently carried out this mod

i run MK4 rear callipers, again these fit our mk3 carriers so its a direct swap, you do need to get hoses made up tho

no need to make the rear discs bigger, just use decent pads

I'll give it a read, I read the bit in the maintenance section but it didnt say anything about the calipers just carriers and discs. Also I meant rear discs not calipers, it was more for looks than performance on the rears thought having 312 up front and tiny rears would look a bit weird :P

Finding it hard to get a set of carriers on their own they all come with calipers but if they will fit on the mk3 its all good. So the whole mk4/a3/whatever setup will fit I just need a 6mm spacer and 40mm high tensile bolts? Where did you get the lines made up, would you be able to get another set made up? :)

Not sure on a mk3 but on a mk4 the 288/312 calipers are the same.

we made the spacer made up ourselves (ben is the man)

i got the bolts on Ebay, super high tensile (you will need to source the washers too like i did)

what is the custom pipes for just the calipers? so if I use the mk3 calipers I keep the standard hoses?
