Cooked my brakes!!!

Bigger diameter = better heat distribution/resistance.

Price of calipers is same as Sierra's: ebay link

That sound like fun, what mods are required to fit to sierra uprights?

You just need 11mm spacers - between caliper and upright (single plates or "bushes" for each bolt), longer bolts (10,9 grade), and sometimes driling hole in upright to 12mm diameter (depends on calipers - Scorpio/Granada Cosworth or Mondeo mkI/mkII V6).





Still need de-rusting and painting... but looks like this

Bolts are M12x40.
I have to drill uprights...

I'll post pictures of my set when I visit garage...

Nice one, I can get spacers made up no probs. Sounds like a fairly easy conversion.

iirc laws of psyics say that the only way for brakes to work is to convert to a diffrent form of energy (heat) so no matter what pad or disc you use heat has to go somewhere.
a grippy pad makes more heat quicker, sintering (adding metal to friction matrial) will pass some of the heat to your caliper etc. making your brake fluid hotter so helps for a short time then cooks the fluid and seals. the best way is to increase the outside area of your disc and help airflow (venting best option)

you can't fight the laws of psyics so just get bigger vented discs

Very true, this conversion to mondeo spec looks like a good, cheap and fairly easy option, I'm also going to look at making some sort of cooling duct like you see on formula 1 cars to feed air into the inside of the wheels.

The wole thing is a trade off between generating heat to get friction from the pad to grip the disc and then getting rid of it to start all over again,choice of pad will make a huge difference over standard application,saying that the Ginetta G20 used standard rear pads,Ferrodo with Ginetta stamped on them a silly prices.

any idea if this is a cosworth or a mondeo v6 278mm disc? the offset is diffrent

dont forget the threadlock

I used to use DOT5.1 synthetic fluid too if that helps and was using red stuff pads with grooved and drilled discs was not allowed to go any bigger due to the technical regulations so have no experience in the difference but maybe try a combination of all the suggestions
