BIG FRONT BRAKES

[vitaminc74]

does anyone know the part number , availability of FRONT HP FIRENZA discs . or maybe a modern equivillent ?. ive got a spare pair of recon M16 calipers , but need some discs to fit . i want to use the standard hubs .

You can fit HPF discs to std viva hubs but you need to make an adaptor bell and machine the hub. Once the disc is mounted then you usually need to skim the disc in a brake later to stop any vibration. I have done this for my 2300 rally car and it is OK. Getting hold of HPF discs is not too easy these days, but you should be able to find some - the list of suppliers in the spares section of the forum would be a good starting point.

I think from memory the code you want is BG35; the standard firenza / magnum disc is BG34.

An alternative is to use the 2.8 capri vented disc and space the calipers, I haven't done this but with a little measuring / design work and machining it should be possible.

Hope that helps

cheers

i have a pair of hpf hubs that have converted capri vented discs, need to space the calipers and have the discs redrilled but its all possible and if they stop a 2.8 capri they`ll stop a viva/magnum/firenza
