DIY Brake Upgrade
Discussion
Merry Christmas and Happy New Year to you all.
I have been thinking about starting my upgrade program with the brakes.
I have read of peoples experiences with Hi_Spec and Tower View etc etc but I was wondering about sourcing the parts myself and have a local machine shop make up any brackets required.
Apparently the obvious choice is Sierra Cosworth 4-pot calipers with 283mm discs from the same and then apparently no brackets are required. As I have the earlier 240mm discs, the cosworth dimensions (apart from the diameter) are within 2mm of my current arrangement.
However Cossie calipers are few and far between so I could just go for the Granada Calipers as fitted to the 500 with brackets and 283mm discs. Any thoughts?
Someone has suggested Fiat Coupe/Pug 406 V6 4 pot Brembo calipers as having the correct hole location for the Ford Hubs. Obviously the discs would need careful selection but the are 287mm diameter so should fit under my 15inch wheels. And I understand that the PCD is the same. The calipers seem fairly available with 2 or 3 sets for sale on Ebay.
Has anyone else tried this conversion or know of anyone who has. I would be interested in any information.
Happy New Year

Did Ian at Godspeed source the calipers and discs for you or did he just point you in the right direction?
Having googled this last night it seems that some washers are required to space the caliper out so that the disc lines up in the centre of the caliper. Is this a problem you encountered or was it a straight swap?
Sorry for the barrage of questions.

The only thing I will say is that be careful and check everything. There is considerable variation on the uprights/callipers/discs over the year and what fits one car doesn't necessarily fit another. This is why many people have had problems with brake upgrade kits in that they fit most cars but one turns up that had a slight difference and it doesn't. Of course we only get to hear of those that don't fit.

There is an AP kit of 283 or 285mm (can't remember which) and the brackets to offset the std caliper. It has to have the bracket as the disc is bigger and the stand off from the hub centre is halfd the increase in th disc size. 15" rims fine.
They are ok maybe 15% better than std with fast road pads, but still not brilliant - but then you can do it all for under 300 quid. You have to tap the std stud holes I think but pretty easy fit. Std 500 brake IHMO are really not very hot for a car as fast as a 500 can go - built down to a price compared to Cerbs / Tuscan.
300mm discs and Tuscan calipers - Awesome (fitted yesterday), and not as much front dive on std suspension as I had heard there could be. The AP's are much lighter than the Grannie calipers, and the rotors are too (alloy bells). Only fits under 16" rims though.

ok so you got me thinking and remebering my cossie days had a close look and hmmmmmm..............
checked ebay............
for the monstrous sum of £100 bought a pair of good sierra sapphire cosworth 4x4 1991-1994 calipers and disks simple straight bolt on conversion 285mm disks great stopping power and they finally fill the wheels properly!!!!!!!!

The 4X4 cossie I dont think has 283mm discs, I maybe wrong but the 283's are from the two wheel drive ones.
I stand to be corrected, I think the 4x4 are 278mm discs.
I have the 283's on mine with grannie cossie calipers.
Infact, check out www.brake-eng.com/
i think the 4x4 front disc isnt tall enough.

really i didnt realise the 4x4 and 2 wheel drive have different disk size i was lucky the disks are from a two wheel drive and fit in the 4 wheel drive calipers so the clearance is obviously there
the calipers seem pretty much the same they both have the same size pistons 60mm and they both take the same size disks maybe its a different offset????they have different part numbers
someone explain to me how to post pictures and i will show you what it looks like

brake disk change is simply remove and install no wheel bearings by the way at least on my car the 2wd 4 pot calipers dont fit straight on you would need to change the hub for a 2wd cossie one which i THINK should bolt straight on (looking for a pair now) also if you fit the rear bearing carriers from a cossie you should be able to fit the larger vented disks and calipers from a 4x4 cossie
Chimtvr, you are right about the rear disc setup, I have fitted Granny cossie rear setup, the discs are the same size(I used modified granny discs because of my spider setup), the bearing carrier sets the caliper further out from centre.The rear disc is 273mm dia.
The Granny caliper fitted straight on, to the standard upright,barr making the holes slightly bigger.
