Mk1 Golf G60 - project :)

[simoncotton]

I have just purchased a really cool Mk Golf GTi with a G60 turbo charged engine in it

however, the braking system does not in anyway match the performance Its running The brakes are drilled 280mm discs on the front, using a TSR kit, and the car has mk2 golf gti rear disc brakes.brake bias pedal box, seperate cylinders front/rear.

Anyone got an suggestions for improvig the braking?

Don't drive so fast?

Quite honestly I can't believe that your brakes aren't coping - I have done two VMaxs and spent all day leaning on the brakes from 120mph, and they were more than capable of slowing my Mk3 (280mm discs too).

I'd look at the pads, the fluid, and the brake lines before splashing out for bigger brakes.

If you do go for bigger brakes you will need wheels bigger than 16/17mm to house the 312mm VAG brakes, and swap to 5 bolt hubs.

Pricey.

^^ What he said ^^

Thanks guys, do u think the problem could be that there is no brake servo at all?

That'd be a good start - mk2's and mk3's always had 'em

Is there any performance difference between a mk2 and mk3 brake servo, and do you know if they will fit?

[neil_cardiff]

Now your getting really technical.

I'm a bit bague, but I'm sure that the master cylinder from a Mk3 will work, but I'm not sure about the Servo.

I'd go with a Mk2 otherwise you may have some problems being over servo'd.

I may, however, be completely talking out of my arse, and I'm sure Iguana or someone will be along to let you know

I assume you mean G60 supercharged engine?- unless its a turbo and supercharged engine or a PG(?) block with turbo instead of a g-lader?

Would have thought youre brakes shouldn't be a problem- have tried checking the pads/fluid?

[hiasakite]

Just realised its a mk1 conversion- question- is it right hand drive?


If so the brakes are notoriously bad on RHD mk1 golfs and scirrocos due to the brake cylinders being on the otherside of the car and linkages between the pedal (on the right) and brake cylinders (on the left) 'flexing'...

It could be this thats doing it for you...

Aaaaah that would make sense then.

There used to be a servo upgrade to a rover servo that used to help with the notorious golf brakes problem.

Any pics? Have a feeling I know the car...

I dont have any pics alex. As far as i remember it was a conversion carried out by Brian Ricketts motorsports at Leamington Spa.
You could probably sort something similar yourself with enough research.

[simoncotton]

The car is RHD and has the G60 with a turbo (not supercharged).

[Bomber Denton]

As the Grolsch boys say...
SCHTOPP!!!

The main problem with the Mk1 Golf brakes is the brake linkage and always has been.

The reason for this is that all the Mk1s were fited with the left hand drive servo mounted on the other side of the bulkhead. To meet the pedal there is something like a 9 piece linkage and as you can imagine after 25 years these tolerances increase massively so you are moving half a ton of Meccano before the servo does it's job.

Autocavan do a bespoke 2 piece linkage. Job done.

Trust me, been there many a time.

This?

[simoncotton]

yes, that's her.

[greatgranny]

You can also get a rear disk conversion for the MK1, don't know how much this improves things.

Decent pads, braded hoses and decent brake fluid will improved things as well.

[alextgreen]

Yes, I do know the car then and can vouch that it moves along at a fair old lick indeed.

Previous owner is a first rate enthusiast and took very good care of it too.

[zcacogp]

The stock linkage can be adjusted - there are knuckle-ends at the end of it. Adjust so there is less play, and things will improve massively in this department.

BUT, also look at the disks and pads (are they toast) and the fluid. You should be able to stop pretty well with that setup.
