Hi @PhilW the caliper that people have tested on here successfully is the passat 3B / 3BG and audi A6 caliper with manual handbrake. people are speculating about using the electronic handbrake version too though.. but i dont think anyone has given it a go yet. would be kinda neat if it worked! whether the caliper itself fits or not and the electronics side (is it just a switch? or switches and sensors to confirm clamping pressure/ when to stop the handbrake motor?) are open questions at the minute I think. cheers, Mark

Wondering, did anyone try these larger piston diameter calipers? I haven’t got around to this job just yet, but curious if the larger diameter versions fit the same as the Passat ones for when I do get around to it. :) Cheers!

cool, thats good! except i`m not sure what kit it is.. the retainer looks like the one i got for a chevette, but i cant be sure the clips are the same size.. the gt6 kit which i used the pins from has totally different clips that i couldnt figure out.. but this image is great to see what i should be looking for. cheers again!

@TAR hey, i dont suppose you also have a shot of how the brake pads are retained in the caliper? ie, the two pins and whatever anti rattle clips/shims are in there? i cant find the right kit. mine has wire anti rattle clips and they don`t seem to fit right.

it wasnt so much to save a few pennies as to find out where they were from.. though i couldnt and still cant find the retaining stuff for pre 85 s3 on SJ`s. however... having tried both kits ( i actually had a vauxhall chevette and a GT6 kit.. neither are exactly right.. its not the vauxhall chevette kit as the pins are too thick.. the gt6 pins are right but the shims in that kit dont have holes in the right place.. and finally, i couldnt work out how to fit the pad spring clips from the triumph kit.. didnt seem right. so i still have incomplete front brakes...

I was under the same impression, but i believe i came upon the chevette stuff from a part number which I cross referenced (I cant be sure but it was a bit of an aha! moment as i was having no real luck finding a fitting kit that looked right from triumph stuff), and discovered the part looks idential to the part in the manual, whereas the spitfire stuff doesn`t look the same, apart from the shims. pads also, similar on triumph but not identical, but possible they fit, though chevette pads from first glance look exactly the same. i`ll verify if the fitting kit is right this week when i go over to the garage. i have both kits to try, a gt6 kit and the chevette one.

Hi all, Ive done some digging around and the fitting kit and pads appear to be from a 75-85 vauxhall chevette. no anti squeal shims in the kit. will verify this when i come to fitting them.

thats great thanks!

Hi all, Does anyone have a pic/diagram of the brake hose/pipe routing and where the small brackets go on the early S3. its just the bit from the flexible line to caliper I`m not sure about. i have one small metal bracket rusted to the old flexible pipe (and i seem to have lost the other) so not sure how the whole thing routes around the coil springs. cheers, Mark

ok, i guess i`ll leave it then, i`m not sure how bad they are leaking, but I dont have the time for a full rebuild at the mo. what about rear main seal? worth doing I guess as theres no getting at that when the engine is in the car? ta, Mark

Hi all, I`m currently replacing the cam belt, water pump and oil seals on a good running 907 to put in my eclat. so a little overhaul. but i`m just wondering what the best way to remove the cam sprockets and replace the oil seals? I`ve currently got the cambelt, and cam pulleys off at tdc, and replaced the water pump, Ive had the sprockets zip tied together so that I dont move them unexpectedly, but it won`t be enough to keep them in place whilst I undo the sprocket bolts. any tips on doing this and on cam seal replacement afterwards? cheers, Mark

ah, thats brilliant thanks. where did you find that diagram? i swear I looked everywhere!

Hi there, I cant find a digram that matches the fuel system layout of my early S3, seems a bit different to whats in the manual. just wanted to check where i need to look to make sure ive replaced all the soft fuel lines, so far ive just done from the flowlock, via a small filter (replaced the plastic one with an alloy one, i had a plastic one in my eclat and after a year the seal had cracked and it was pouring fuel). before the flowlock valve it is hard steel line, which disappeasrs off behind the engine.. what soft lines are between this and the tanks? cheers, Mark

i have one of these in my eclat - http://www.fuelflow.co.nz/FF_cms_03/eshop?page=shop.product_details&flypage=flypage.tpl&product_id=66&category_id=28

one other thing I heard can cause a fire is a rupture in the oil line to the oil pressure gauge too, probably less likely than a fuel fire, but still worth looking at i guess?
