Hi guys I'd like to ask a question re brakes as we're on the subject so not to post a new thread  :signLOL:
My leading pistons are the smaller ones at the top and was wondering if I was to swap the pipes and nipples over so that the bigger pistons are at the top and would there be any difference in braking?.

PFA thanks

I cant answer you R5GTT, but I'll just chuck my tuppence in here on the R32/standard brake thing.  I have a standard Ed30, road use only,  and I was horrified with the standard front brake set up.  My problem was that increased brake pedal pressure (in those emergency "oh sheeeet" moments), had no effect on stopping power, it was like pressing on a lump of wood.  I wondered if I had a problem, put on new discs, pads, checked everything - same terrible braking. Fine for 30 to 40 mph town use, but nothing else, and in my opinion dangerous for emergencies.

Swapped to R32 calipers with braided hoses and 340mm TTS discs - halleluyah! Brakes again!  (I came from a MK2 G60, with standard 280mm front brakes and single pot calipers, so that it was I am comparing to) .

Yes, the calipers are heavier, but the only difference I initially noted was on steering feel, no big deal at all.

Weirdly the R32 pad area looks to be the same as in the standard ED30 caliper, the huge caliper size difference is due to a supporting framework around the caliper, i presume to reduce twist , allowing more braking force to be applied. Plus of course the force is being applied to a 340mm disc, not a tiny little 312mm, and perhaps the caliper piston is bigger.

Well worth putting the brakes on.
(Presumably VW had run out of money on the ED30 and ignored the brakes, the R32 only has 20 bhp more, is heavier, but came with bigger front and bigger rear brakes as standard. )

You want the small piston at the top, for cars that have the caliper on the front of the hub.

i would agree about the poor braking with oem ones as I've had this with other cars so definitely the way to go.  :happy2:
The pad sweep area are the same but the pistons on the R brakes are bigger so better for braking force allowing the car to stop a lot quicker  :driver:

@r5gtt I think this DIY will help you: http://www.mk5golfgti.co.uk/forum/index.php?topic=35226.0:smiley:
thank you for that @Shoduchi I've read the thread yeR back but didn't save it but very informative and I think I'll be fine with the way they are now as mine are turbo front calipers and not boxster rears so it won't really matter which way round the pistons are although I was told differently by the refurb specialist in Nottingham or was it Coventry off facebook a while back and when I was looking at my calipers last night wondered if it would make any difference. :happy2:

Thanks @rich83 was told different but then again there would be no difference as our brakes are front hub mounted as I've now realised reading that thread Shoduchi posted that some rear calipers are fitted at an angle so the bigger pistons would sit forward.

Nothing to do with angles. It's to do with the small piston being on the leading edge of the pad

It may have been said already but you can offset the better S3 brakes weight by fitting the allot lower arms found on some passats, cupras or the SuperPro version  :)

I was thinking of fitting the S3 bones with the superpro ALK I have but doesn't that take the wheels out further camber?.

As far as I am aware the S3 wishbones are just 1kg lighter than standard GTi ones.
