This setup is on a Alfa race car from back in the 80's they had regulations in the BTCC so they were limited to brakes size and had to run on 15's

I am now building the same setup for the Fiesta/Escort and the conversion bracket, bolts and braied pipe work will be about £80? you will have to find the 2nd calliper yourself.

What do you think? cheaper than most 4 pot conversion

[XRMike]

good idea mate. i have got some st24 brakes to go onto my xr2i but they need maching so i'll see how much it'll cost. do you rekon you'll be able to knock a rear disk conversion for the rear?

[freak power]

I could do

[XRMike]

cool,they would be a good seller. so what disk do you rekon you'll use for the front?

[freak power]

It depends on what the customer wants?

Any disc/caliper combo really

[XRMike]

cool, sounds like a good idea. good luck with it mate and if you can make a rear disk conversion i might be interested

[Pez]

Its an interesting set up, although, i would suggest uprating the master cylinder to go with it. Your master cylinder will be operating to twice the capacity of normal, so it will lose pressure, lose pedal feel, and in fact, lose braking force. Novel idea though, good luck

There is a thing as over braking i have spoken to 2 of the best rs garage's in the uk and putting brake's like that is ok to get the wheels to stop but it's the tyres on the tarmack that you have to get to stop and the faster you get the 15's to stop the easyer it will to get the ruber to slide on the tarmack that why tvr's and car like that have tyres as long as to 195 put together

When I was about 16/17 and in training I asked my tutor why a brake set-up like this isnt used on high performance cars, I dont really remember all his reasons but one was the Cost of it (X2 pads, calipers etc), if you could make them I think id be interested but as said, you'd need to uprate the master cylinder to cope.

How would the brake hoses work? i.e would they have a T-section to the extra caliper

Would that not overheat the discs even faster?

mayby a little more, but due to having more contact the braking force should be better to componsate. one problem that people may encounter with certain disks is it they might warp easyer and quicker. still worth a go, nothing wrong with trying.

Same thing. Warping a disc happens when the disc gets too hot

[XRMike]

true, but i was also thinking of brake fade too

[heeman10]

It's a good idea, and would look good, but I wouldn't do it due to the additional weight. A key goal is keeping unspring weights down, so adding a caliper and mounting bracket on each side is a good way of increasing the unsprung weight. Also, if you're trying to keep this budget, I'm assuming the calipers won't be lightweight aluminium

I'd consider it on a heavier car with wider, stickier tyres, but I think the additional weight is unnecessary. How much do you think the cost of the whole kit (ie brake lines, calipers, disc and mounting brackets) will be? Discount the cost of the master cylinder, as most four pot calipers would need an uprated master cylinder anyway.

Yes it's a good idea but disc cooling will become an issue during prolonged use.

Full-circumference disc brake systems are the future of braking, the effort is so great that they will run without the need for a servo. These type of systems are a few years off at the moment though due to production costs

Wot kinda master cylinder have u used with uprated brakes? I have a low budget mk3 rally car project and fronts are single pot cossie brakes (rear brakes are under construction for now). Wot do you recommend?

[freak power]

Right now i'm running a Mk5 Fiesta master cylinder and servo, it give a much better petal feel also ive changed the pedal ratio

[Mizka]

I'm gonna left the servo out for better brake feel, but is the mk5 master cyl really any bigger? How's the install, is it bolt-on?

How did u change the pedal ratio if I may ask?
