Brakes - 280mm cossie or 308mm/4 pot brakes

Problem or technical question?

Brakes - 280mm cossie or 308mm/4 pot brakes

Postby Stoned on Mon Jun 23, 2003 10:15 pm

As above

is 308mm discs and 4 pot calipers on a Fez too much, would it lock the wheels too easily?

Oh just one more thing. The 308mm discs have an aluminium centre. would that make them lighter than the steel 288mm discs from say a cossie?

Not sure what I should be saving for right now. Either way im gonna move my existing RS2000 brakes to the rear wheels :D

brakes will be better on 308, less prone to warping, sep rotor and bell, discs expand at diff rates from centre to edge thus warping, over 300mm and u get sep rotors and bells so that the rotor can expand at diff rate to bell and not warp.

OK

THe benifits sound promising. How about them being a tad OTT?
And are they lighter?

I dont wanna weigh my car down with unnecessary weight.

lol stonedwor your power 308mm brakes are overkill

your rs2k brakes will not go on the rear

rear disk brakes are completely different to fronts ie handbrake etc lol

Yeah but fiesta centres kit lets you use pretty much anything mate

If I cant then it aint the end of the world, I'll get some cheap calipers and discs elsewhere

May only be 150bhp now but that will change :)

depends on size of your wheels, if u run 16,17 inchers then you have reduced your braking capability already, aint overkill if u use em, i do lol, car will still do 140mph, if u gotta stop at that i would rather know that i`ve gone ott and they aint gonna fail than find that they fade off at 30mph

Yeah snake thats the trouble dude. 17" wheels are heavy!

I've got RS2000 brakes on the front which are better than standard but not much. Recently I had to stop very quickly when some gammon slipper just changed lanes right in front of me without checking his mirrors. He was almost stationary in a queue and I was in the other lane doing about 40

When I braked they bit quickly as I would expect but then to my dismay just faded away like on my old 1.6s

Luckily I wasnt going faster or I probably would have bumped into him

So yeah, end result was I decided the brakes were pants and needed better ones.

Good job you stopped m8. I now have disks all round, but i had to uprate to a MK5 Escort Servo and master cylinder.
I have cossie brakes all round and the piston bores on the calipers are big, and the fiesta master cylinder is like a pee shooter!

Sweet

Mikey is it easy to change to the escort master cylinder?

If this needs doing I shall do it at the same time, oh and I dont suppose the escort master cylinder includes a bias valve does it?

Cheers mate

Your car has already two balance valves strapped to the inner wings behind the battery. Yeah the change over is easy for the servo and master cylinder.
