A Bit Market Research. (brake kits)
Turbo Mini Forums

ok thanks to a member of this forum, i have got my hands on a pair of mk1 fiesta calliper carriers, as we know these are now rocky horse shite !! i have an aquantence who is a CAD and CNC lecturer, whom i have given the carriers to to get patterns made up for them, he is of the opinion he can CAD the items quite easily, and on the machines he has access to he could knock em out in alloy. EDIT: or Steel

would this interest anyone on here ?

i could do just the carriers or do them with new callipers as sets, all that would be required would be to get the discs turned down, however this again would be a facility i could arrange at realitive ease.

for those that dont know.....this would enable use of ten inch wheels, and as i have run the fezzy route before i can recomend them for braking power.

if there is interest i will look into the material costs rather than just make myself a set !

You will need to be very careful with material selection.

I'm not sure aluminium alloy would provide the correct sliding properties and it would be prone to corrosion.

Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."
Stephen Hawking - "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."

Mk2 route might be better and easier to get hold of the re-engineered calliper. The carriers on the Mk2 have two bolt holes to bolt the sliders into, which come as part of the new calliper...

This is the design Ford stuck with for the Mk3 etc, the Mk1 was very different from what I have seen.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

As per Paul,

But also, aluminium alloys may not have adequate strength if you just matched the carriers size for size.

I don't like to sound negative but the use of aluminium alloys as structural materials needs careful thought.

Does the college have decent FE software that could run the stress calcs from a CAD drawing for your chosen material ???

Schrödinger's cat - so which one am I ???

Is there a way designing the sliders and caliper spacing so you can get away with the metro turbo flanges? That would be cool!
I bought new mk2 calipers and sliders for £100 delivered (germany)

Make them from steel. If folks want weight saving, they'll fit alloy calipers, not fiesta ones. If folks want cheap 10" calipers, they'll fit fiesta ones.

Figure out your best market potential and take it from there. Do bear in mind you need to keep costs WELL below the price of Alloy 4-pots.

Another idea - don't the fiesta caliper conversions need the expensive / NLA non-vented flanges or somet? How about rather than plagiarising a carrier, you make one to actually fit a caliper straght onto a 8.4" disc'd mini with no other mods? Maybe consider other calipers from other vehicles?

yep you need vented metro flanges to space everything correctly.

There was few people in Finland I think that made spacers to fit on the drum braked hubs, so the F-stuff bolts straight on. Check the TMF post.

Honda have also been used

oh as a guide price I think my conversion cost me about £350, inc new bearings, ball joints, buying used F-brakes and then swapping them in for new ones at the local factors, new discs ( I got them machined for free), new pads, a set of 8.4" hubs (which were complete), new drive shaft clips, new braided hoses, 1 inch spacers for the rear, and new studs all round.

I was going from drums, and as the car is used now and again I didnt want to trust old parts, so not cheap but in my eyes still cheap for a full conversion with all of the extras people sometimes miss-out when costing up just a set of ally 4 pots.

no probs. the material can be what ever, to be fair i would have rather used billet steel. the feedback is good, not sure what stress programmes etc he has, but i could have tests done at another department.

keep the feedback and ideas comming folks if i have access to provide summit we might as well decide on summit that will work

Just make it out of steel - then the stress problems go away LOL.

mine recorded 185 on the brake test

big stainless pistons in those fezzy callipers........great !!!

anyone know what the standard brakes record? and also ally 4 pots?

would be a good comparison and possible a good sales pitch

my standards were about 160 with stainless psitons in them after a fresh rebuild, not sure about the ally 4 pots
