anyone clued up on these a just bought a series1 with a set of 2wd cossy discs but it has standered turbo discs on the front seem ok but not had to slam on yet can anyone see this causeing a problem

 

I stuffed my s1 last week i had cossie discs on bak and front but no bias valve!

 

where u get the iger stripes was thinking of doing that to mine as i remember when they first came about in the early 90s the met grey series 2 looked mit with the green and light grey ones

 

Yeah big problem mate as KidRS said!! RIP his S1!!

I'm slapping Focus ST 300mm bad boys on the front of mine as I dont want the risk, even then i'm going to test them and perhaps add a bias valve to be sure!!!

 

This came up a little while ago and I said about the over breaked rear end and promptly got shouted down by a couple of users. I hate to see anybody damage their cars but maybe the shouters from the other thread might like to now read this?

 

PF for you mate always someone ready to shout about something

 

don't see the point in rear discs if you have to tame them with a bias valve, mite aswell leave the drums on, although discs look better

 

Agreed mate, which is why i'm 'Going Large' on the fronts and am hoping i can leave the backs un biased!

 

get shot of the rear compensators too !!!!!.

or go the whole hog and get braided lines throughout and a custom pedal box replacing the servo with in-car adjustable bias on the dash ( like moi ) .

dave.

 

mines got 4x4 front calipers, with 283mm discs seems to stop perfectly well

 

probly put the drums one from the one i have just stripped

 

Im hopefully having my car repaired fingers crossed so ill be fitting a bias valve of some sort next time!! Place that did my stripes has gone bust now dude.

 

im ruunning 2wd cozzie set up on the back,got st170 set up on the front no bias valve never had the back lock up on mine the compensators were also removed

 

My fucker locked up royal!! matty uv probly never driven hard enough to have to use your brakes hard enough??

 

ha ha vfunny !

 

If the compensator is removed wont it brake more at the rear as it restricts the braking based on load and would have 100% now all the time?
Although I think mine is differnet to normal RS's it's the same as the van and estate models, just one in the middle at the back. Dont know if that makes a difference?

 

If its locking up on the back and your on standard suspension you will possibly want more braking on the back not less, so reducing it with a pressure reducing valve is going the wrong way

 

How will more braking stop it from locking up, if it's already locked up?
I'm on Spax adjustables BTW, i've not actually had mine lock up but after hearing about KidRS i'm concerned.

 

so did i bud!always said there a bad idea!!

 

Think about it Karlos and think about why its locked up !!

 

I have cossie 4pots on fronts 283mm discs and cosie solid discs on back and i have no probs..

 

lol... i'm confused!
Has it not locked up because the braking force is more than what the tyres can grip?
So to not lock up you either need better tyres/suspension or to brake less?

 

I think where Tony is going is that because teh front is braking hard the weight transfers to the front thus making the rear of the car light and as a result more likely to lock up. By increasing the effort the car will brake more level and thus stop quite such an excessive transfer of weight away from the back of the car

 

you must have read my PM I sent to Karlos this morning

If it locks up under braking it could actually need more on the back to stop it, depending on what its doing.

 

See I might be slow but the grey matter ticks the right way

And my typing seems to have gone to pot as well re-reading what I typed

 

 

Thanks! Yes that makes perfect sense!
I think it's going to be a bit of trial and error with a bias valve to get the balance between front/rear just right then.

 

think with a cabby ur better off then with a escort, would of said there was more weight over the back wheels?

 

im scared now was going to put 2wd cossie discs on back and got 4x4 discs on front with std rs callipers on front will this kill me !!!!

 

Im running the same as you still with the rear compensators and ive had no bother, i know ive driven that hard enough as come back the other day and all 4 brakes where smoking, but thats what you get when trying to stop a YB powered rst.

 

will it be ok or will i need to put better brakes on the front ?

 

just put a pukka set of front stoppers on m8

 

What suspension is it on Martin ?

 

gmax with 30mm drop im tryin to keep costs down so was just wondering if the std turbo callipers with cossie discs on front will be ok with the complete 2wd rear disc conversion its only a road car and i use it everyday
