View Full Version : Brake upgrades for Mk1

Hi fellow vdubbers, have any of you carried out brake upgrades on mk1 golf?
Not just performance pads but real stoppers to compensate for big hp and to use in racing applications. any info would be appreciated wether it is something that can be retro fitted from another vw or audi, seat etc. or brakes from performance aftermarket type setup.

A bigger master cylinder and servo is a good start. MK2 items being easyish to obtain, Passats have the same stuff fitted if you find one.
The disks and pads depend on what you have fitted to start with. On a GTI you can space the caliper to fit 280 G60 disks. Not sure about lesser models as I have never run one.
I think some early to mid 80 Audis had 256mm brakes which will go on mk1 hubs.
With 256 you are going to need 14 inch wheels, with 280s you are up to 15s minimum.

thanks for reply,would definitely be looking for 270/280mm discs and calipers, even some 4 pot calipers to suit.Am using mk2 booster but have not done master cylinder yet.Am going to add some serious hp so i need stoppers.

A mate of mine has a Turbo Technics MK1 with 175hp that he runs on std GTI brakes. I think he is mental but it does stop OK, just doens't feel like modern brakes.
How much power do you think you'll be ending up with?

Due to the fact that i want to use it for a variety of competition,and not knowing exactly what engine i will use,i suppose hp figures are a bit way off yet. But i am a big believer in having more brakes than u need rather than less.
I was reading in a gti book about one conversion that uses hubs,280mm disks and calipers from Passat 88-92 but i think this may be an English or European model. As yet i dont know if this model is in Australia

Christ I was scrubbing huge speeds with 239's using decent pads and fluid at the Island. Still have the mk2 - 239 set-up. Anyones for a case of Stella!

All this stuff is available, you just need to look around for it ( overseas web sites )
Will be ordering some 280 front discs very shortly..

You could use some cailper brackets,
I bought some from Ridgeway racing in the uk, They space the original caliper out so you can fit G60 280mm discs, very simple to fit, only hard bit is you need to machine 1mm of the pads.
You will also need 15" rims to clear the calipers.
These brackets fit all mk1 Golfs and early mk2 Golfs with 76mm spacing between caliper carrier bolt holes, I havnt fitted mine yet but ive been told these make a huge difference
Have a look at the pic.
I also have caliper brackets which allow the fitment of Porsche boxster 4pot Brembo calipers to mk1 Golfs and early Mk2 Golfs, (only with 76mm spacing) these need 305mm discs from a Seat ibiza cupra r (4 stud) Part no 6KL 615 301 these bolt straight on, not sure if they are avaliable in aus?, and some different brake hoses. ive been told mk3 hoses will work?
but you will need at least 16" rims to clear the calipers.
If there is enough interest i may get both these brackets made up locally.

Thanks for the reply,most of info that you can get seems to come out of UK or USA, obviously the Golf scene is so much larger in the UK. It is good to be able to share info in Australia with fellow golfers. The G60 disc conversion i have read about, i suppose it is then relative to what wheels i then run.

The G60 disc conversion i have read about,
They're easy to get as they are Passat brakes. Same as G60 at half the cost.

Most Passats are 256mm where the G60 has 280s. The hubs are the same and the 256 Calipers are only slightly different. If you have 256 calipers and 280 disks you need to make the pads thinner. 280s are 22mm thick to the 20mm on the 256.
It's a great conversion though, we fitted this stuff to evorobins Golf with big success.

The parts are exactly the same, but you have to pick the correct Passat.

Phil, can you elaborate please. All the Passats 88-96 I have seen except the G60 (not in RHD) and VR6 (all 5 stud) have 256mm brakes, some being solid disks the rest vented. The only 4 stud 280 I know of is the G60.

Isn`t the cupra sport 280mm 4 stud too? And you can get disks in Oz.
Also what Audi brakes are good? I am wrecking an Audi 100 this week 1991 Model. Any good bits on it?

I run 270mm Black Diamond disks with standard GTI calipers.
They came from TSR, who unfortunately have since disappeared),
They are special though
as the 'top hat' has a much deeper offset to allow for the adaptor plates moving the calipers further inboard.
The benefit is that wheel clearance is easier - they will fit under 14 inch wheels.
You may be able to get them direct from Black Diamond, but the tricky bit would be the adaptor plates though - they came from TSR.
Otherwise , I'd investigate an oem 280mm setup along the lines of some other posts here (15 inch wheels required).
I believe that 305mm brakes are available from a Ibezer Cupra R, if you want more serious stopping power, but don't know the pitfalls to watch out for.
Of course there are a number of upgrade kits available OS, if you have the dough...
MkII rear disk conversion next, followed by a MkII servo/MC upgrade.

Depends what year?, 16v Cupra's had 280mm 4 stud discs, the 20vt powered Cupra's had 305mm 4 stud discs, with the 305mm you have to use the brembo calipers as the discs are
28mm thick, VW calipers wont fit over these.
Who sells the 280mm discs?

They only brought Cupras here until 1999 and they all had 280mm 4 stud discs. A friend of mine bought some new discs for his for $150ish, I`ll ask him where.

Caliper left 357 615 123B 88-97 Passat
Caliper left 443 615 123FX Most Audis from early 80s to late 90s.
There are 2 different types of caliper which changed from 90-91.
I made a mistake with the disc as I did not realise that the V6 Passat was introduced in '88 which of course had 5 stud wheels. So the Passats that had the 280x22 disc (4 stud) were G60s anyway.
So for a cheap conversion you can have a look around for an old Audi 80/100 locally for the calipers and by new discs (or get them made). Or you could redrill some VR6 discs.

Was talking to a friend in the UK last night who was suggesting that early Vectra (& Astra of the same era) front calipers will fit Mk I's (& from my interest Scirocco's).
Apparently you need the Vectra carrier, caliper, hose and pads and use the corresponding VW disc. I think most early Vectra's out here came with 256mm and 288mm (V6) discs?
Only fiddly bit is the bolts which need a little engineering.
Anyone come across this one, tried it, got any feedback?
One imagines that there are an increasing number of early Vectra's plagued with expensive computer and sensor issues starting to hit the wreckers yards and could represent a cost effective upgrade.

No they didn't :)
The Mk3 Cupra R (180BHP) came with 305mm Brembo 4-spot brakes, the other 20vT Cupra (156BHP) models use exactly the same Lucas 280mm setup as the Mk2 Cupra 16v.
The 280mm discs are easily available for under $100 locally!!!

You need to be careful with wheel choice when using the 280mm brakes as there isn't much that fits over easily.
