Has anyone gone the DIY route for a Scooby brake up grade?

I have seen a upgrade kit at the Movit website which upgrades brake for lots of cars including Scooby’s (see

I don't think this is an area for DIY unless you really, really know what you're doing.

Why not get a pair of 4-pot calipers off a MY99/00 car? They're quite often advertised in in the For Sale section. I believe they bolt straight on. As I've just upgraded to an AP kit, you can have mine for £200 (calipers, plus well worn DS2000 pads, plus newish standard pads, but no discs).

hi psyg

I thought you felt terrible after
having a drive with Patrick and
his Porsche 968 on the Nurburgring.
Mostly this is caused by braking power http://bbs.scoobynet.co.uk/biggrin.gif

Cheers mate

Rene

PS I felt not so wel too...

Hi Rene

...never thougt you find your way over the canal... http://bbs.scoobynet.co.uk/wink.gif

Indeed I felt terrible then,
BUT it was in my own scoob on the hot seat with Dick (10 years Ring-experience) driving the car; and it was because of G-forces, speed and the LACK of brakingpower... http://bbs.scoobynet.co.uk/eek.gif

So much difference in another scooby with the same speed & forces, but an AP kit! (... and it wasn't my car driving on the limit, hehe http://bbs.scoobynet.co.uk/smile.gif ).

And yeah, better a Scoob with porsche-brakes, than a Porsche with scoob-brakes, no?

Iain,

I have a 94 WRX with the same wheels and I got a big-disk upgrade from Hi Spec in Dartford for £400. This uses the standard 2 pot caliper with a custom bracket which moves it out slightly. The disk is a 315mm x 28mm disk with a separate bell.

It works very well and would be easier than fabricating your own brackets....

See

With the greatest respect (why does this expression sound so hollow?)
Steady there with the making your own brackets thing - You may well void your insurance at the very least. you are in specialist territory here with extreems of temperature, shock loading, metal fatigue (or is that mental) and other stuff that i currentkly cannot think of (or up) & stuff (i am sure that some will give a more better'er explaination.

Simple rule of thumb DIY + brakes = Dodgy ground

Sorry it has taken me so long to reply to the posts, had a couple of probs. with the old PC (and yes I do work in IT). http://bbs.scoobynet.co.uk/tongue.gif

Anyway…. Why is everyone saying brakes…. no don’t do it. I’ve got a garage full of Snap-on, a lathe getting dusty and a friend who works in NDT (non-destructive testing) who is more than happy to check out anything I make.

Come on, someone must have tried something like this. (Or am I mad Paul?) http://bbs.scoobynet.co.uk/biggrin.gif

GavinP what were the custom brackets that you got from Hi Spec like, i.e. were they complicated in design or just a bit of ally that had been milled to fit (I am not saying they are c**p I’m just interested in what you think). And how much better is the braking now you’ve had it done?

Hoppy Have you still got your 4pots? if so could you mail me and perhaps we could sort something out (I may let the lathe stay dusty you never know). iain.harrison@ntlworld.com

Crusty I would really be interested what set-up you are using. You say that it came on a Sti-2 who makes this kit? As for the size of the master cylinder I have the formulas needed to work out these things at home. I will look them up for you if no one does it first.

Thanks for all the replies

Hi there,

Most of the brackets supplied by brake companies are simple machined lumps of aluminium.. AP.. Brembo...

They arent anything special.

Ideally you will put a few engineering principles into practise.... do radius/fillet edges/bends, as opposed to straight edges...

I say go for it. http://bbs.scoobynet.co.uk/smile.gif

ps - A milling machine would be far better to produce brackets than a lathe http://bbs.scoobynet.co.uk/wink.gif

Hi Yee, I'm in the process of fitting Porsche 993 four pots (front & rear) to my '93 WRX-RA. These came on a Jap import STi-2. Discs are 315x30 and 315x15. The kit included brackets,braided lines... etc. What I need to find out, is if I need to change the size of the master cylinder... are the MY99+ cylinders larger to suit the factory 4-pots ???? Someone help !!

That’s the spirit (of course when it all goes horribly wrong I’m holding you totally responsible) http://bbs.scoobynet.co.uk/smile.gif


I know I could do with a milling machine…… You haven’t got one have you? If you could just pop it in the post there’s a good chap. If not I shall have to make do with the old vertical slide attachment. (thought you had me there didn’t you…….now where’s that book “Janet & John use a lathe” http://bbs.scoobynet.co.uk/wink.gif


Thanks for the input J, what brakes are you using?

Any body with AP.. Brembo...etc brackets out there I’m sure they are very special. http://bbs.scoobynet.co.uk/biggrin.gif
