has anyone used bmw e38 brembos on there cossie. are they worth upgrading to do they warp the discs easily as i found on my old evo7 those brembos warped diff type of discs

daz1968

I would have thought for calipers to warp discs one of the pistons must be stuck slightly, looks a good conversion though and brackets are easy to get, also using focus discs makes it easy to get replacements. If I had 17 inch rims it's the kit I would try as cheaper than focus calipers as well.

calipers dont warp disks fella, heat disipation does, i.e shit quality or abuse!

E38 technology is old, like cosworth 4 pots, same era.

i would reccomend Evo4/5/6 caliper as there cheap, and run 330/360mm disk depending on spacing.

but the disk, many choices out there on 4x108 pattern but only buy branded stuff, pad choice is critical but purely on your useage application, fast road based compound or knockhill flat out late brake affair

focus rs gear is a simple fit, even got them under my 16" rota wheels on my xr2.
cheap discs and pads tend to cause warping.

Cossie Sean

if size is a problem (fuck off, i have no idea why women laugh when saying this to me ) then smaller Brembos, Focus mk1 RS are same as Seat Leon Brembos, more readily available and obviousley el cheapski!

cheap brake fluid makes you brake harder and cause excess heat = warping

i find the main cause of warping discs is hard braking then coming to a stop and leaving your foot on the brakes as you are effectivley clamping say a third of the disc and causing heat in the clamped section to dissapate into the pads and caliper etc.. while the rest of the disc is cooling at a different rate

Cossie Sean

this means the centre point of the floating parts, either pads or caliper, in more offset to one side,

id guess less than 10% of folk brake from say 40mph and keep their foot on the brake pedal after they have stopped, youve either crashed or passed the obstacle by this point surely? so then the pedal is released?

warping is caused as you say, by heat dissipation , this is generated mid brake than standing stop id guess, if im wrong i dunno, this was a genuine physics question, once stopped or massivley slowed the loss of mass will create less heat due to less kinetic motion maby?


purely expansion and contraction = fucked cheap shit

Are the bmw brembos alot better or just a wee bit better i dont want to bvy them if theres just a little bit better

Cossie Sean

cant answer that, but id imagine old technology vs new will speak for itself.........

or sat at traffic lights with foot on brake blinding me with brake lights like 90% of drivers round my way lol

a calliper is just a housing with a piston that moves. as long as the tolerances are correct then none should be better than others within a manufacturer with given materials.

Cossie Sean

greater surface areas and pressure forces throughout the surface area of the pad are better, i would have thaught i.e 4 pot better than single pot i would guess from a phisics point of view surely

botters, we have the same fuckers drive round here like that lol

Can you explain this statement please?
Because as far as im concerned they are completely different...

Better than what? What brake setup have you got at the minute?

Cossie Sean

i dont understand your question fella.

Where can you buy brackets to fit the Evo 6 brembos to the escort cossie?
Iv got brembos sitting ready to go on, I'm already running 330mm discs with the standard calipers.

pics on your 330 set up with standerd calipers please

306 COS

Dont have any pics at the mo as offshore, the caliper has a bracket kit on it to fit the 330mm discs.

Well in the previous post you said e38 brembos are old technology-like cosworth 4pots, i just wondered why you say that?

Cossie Sean

calipers fitted to Lambo diabalo, De tomoso pantera, R32 GTR and 8 series BMW are old technology, infact first used in 1983, like cosworth calipers, same era. technology is not moddern day, nearly 30 years and in my eyes thats old,

the unsprung weight makes a difference and i personaly would go for newer designed, lighter and more capable calipers

but preferance is purely down to owner

im not saying im right, just that it is my opinion and what I would do

You have said that as far as your cencerned they are completley different, that is your opinion and your entitled to it, but why do you think this,
more valid points decisions can be made better

ive been lucky enough to have worked in motorsport and seen top names regularly, not mainly road cars but pukka setups, and i say what i see

Just buy a tidy set of 330mm AP 5200's, more brakes than you will ever need for the road

Cossie Sean

budget depending id buy alcon but its not my cash

as said FRS will work with 330mm discs fine, you can make simple brackets to fit them on too for a cosworth.
light weight 4 pot brembo's fitted then.
the weight i added with 324mm discs over 278mm cosworth ones was offset with the much lighter frs callipers over the 4wd cosworth callipers.
overkill on my fiesta, but i wanted to make sure the car can stop from speed quickly.

YOREVOL

ive just fitted this conversion and i found the calipers to be quite light so i cant see much of a problem there. the only thing that concerned me was the pistons are different size top and bottom, i'll have to let you know what i find driving them later as its sorn at the moment.
all in all i am impressed with the conversion, for @£200 i have a brembo and 325mm disc set up.

am still looking for a good coversion for my 4x4

steve st220

i've bought brembo's off a bmw 750 to fit to my ST220 for a bargain price of £24.

how hard is it to make brackets to fit them, i'm going to use mk2 focus rs discs.

YOREVOL

ive fitted them to my xr4x4, had to drill holes bigger in brackets and used 2 washers to space the caliper.
