Mk1 Big Brake conversion

Seen a few kits about but reckon I could assemble the parts myself? I was thinking Seat 1.8T ,4 x 100mm ,305 x 28 mm discs.and Brembo's from a french car would only need the adaptor plates making up then? what would be the grade of alloy required or would steel be best?

Anyone carried out a similar conversion?

 

I happen to have a nearly new TSR "big brake" (285mm) front brake kit for mk1 Golf - discs, adaptors plates and bolts -- everything you need for an easy upgrade -- would you be interested ?

Cheers, Will

The TSR kit is fine for a fast road car, but the pistons in the standard calipers (which the spacer kit re-uses) are a bit small for serious performance.

I think it was Brunty who said he had 304mm brakes... sounds close to 305! Lots of Alfas seem to have big Brembo calipers too. Just a matter of finding something the right size, with a suitable spacing. Vauxhall spacing from some models tends to fit a Mk1 - anything suitable in their range?

 

RJ this sounds interesting,I am running a TSR 285 kit at the moment and as Mike says calipers are not great so was thinking Brembo's off a 405 and as stated the Discs off a seat hmm best get serious about finding these caliper

 

How much power are you running please ?

BTW ... Tarox will do you a six pot caliper / 280 disc set up.

 

running just shy of 150 at the wheels and although brakes are fine for brisk driving on the road, really fancy making sure that brakes are at the ultimate spec,alreaady running Autocavan Brake bar,Bias pedal box and TSR 285 kit ,maybe I should just consider upgraded calipers and keep at 285mm?

 

Thanks ...

My reason for interest is that I also have a Mk1; runs the TSR 270 kit with Pagid FR pads and with 140bhp flywheel would manage six laps of Combe / eight laps of Knockhill before starting to fade.

To compliment it`s `new` 16v my plans are - DS2500 pads before looking to change calipers, I want to retain the 14" wheels.

 

Quick question does anyone know the distance between the mounting hole on a std GTI caliper? seen a few caliper possibilities Many thanks

 

Ok so settled on a pair of Audi S2 twin pot calipers going to run them with my existing disc set up and a pair of caliper adaptors from EPYTEC in Germany unless anyone knows of a UK supplier?

 

76 or 78mm rings a bell, but I'd need to check to be sure.

 

No you are spot on fella it is 76mm and the newly acquired Audi calipers are 93mm ish? anyway by the by found some caliper adaptors but wondered if anyone in UK was making any before I ordered for the Fatherland!!

 

I think the later ones are an even number too. Can't remember if it's 92 or 94. Close to your measurement either way.

 

well I have fitted 312mm fronts from mk5 GTI adaptor is really simple

The mk5 calliper option looks good, what size piston etc do they use?

Fancy 300's on my 16vt, any other opinions welcome too.

I have g60's at the min with conversion brackets. But got 16's now and have a phobia of brake gap.

 

Ive got a set of corrado G60 calipers for the front and rear of my mk1, can anyone recommend a servo and master cylinder to use with them please?

 

A 9" servo and 22mm m/c should do ya.
