hi all,

I've currently upgraded my brakes to 4pots on 330m discs up front and 300s to go on the rear with abs removed, they problem i have is with the current standard servo , cylinder. they seem to be on their way out, signs of leaking etc. now my question is what would be an ideal upgrade? How hard are these pedal boxes to fit? Are they a worthwhile upgrade?

Cheers

Im also considering the Pedal box upgrade.

The one like Christian used on his s2, the gartrac one is £350+VAT as they have to be specially made, and would probably be the best option to take as uses up the least room, but there others out there such as a universal pedal box, or one found on compbrake which is listed for a series 2 escort.

this is as much info as i have really got at the moment mate, hope it helps out abit, im sure there are others that can shed some more light on this!

creator

i think crazycage and his mate fitted a focus rs one but id wait for him to see this thread for definate answers mate

crazycage

yes i did one for project'rs off here as a direct bolt on part

StephenC

Seriously mate your like a pioneer in the rs turbo scene. Any loose info on the pedal box? was it a bitch? understand if you dont want the world to know, worth a try though

crazycage

thank you .im open with all that i do! I didnt do anything to the pedal box just the servo and master cylinder and braced it up a tad to help stop it flexing.get a friend to push the brakes hard and have a look at the movement in the servo!

crazycage i think my s1 might end up at yours soon lol.... theres a few bits i want doing lol

cheers for the replies so far guys,

ideally id prefer something which more or less just bolts on. With the compbrake one listed about what fab work i any would be required and what additional parts would be needed.

Would the standard brake bar still be of use?

Apologies for the basic questions still discovering new aspects of my car!

Thanks in advance

project rs

yes you still use standard brake bar with the compbrake one and the one christian had made for his can be bought of another source on here tony aka nutsrus or something like that and mine was pretty simple if you can weld and makes a big difference

Ive just brought the compbrake one, i trial fitted it and looks easy. Muz has just fitted it to his so drop him a pm with questions on it.

cheers guys, been very helpful!

muz

I'm using the compbrake bolt on job. Very easy to fit.

hi mate, which option did you go for on the master cylinder size? Did they supply the reseviour? And finally have you tested it? Any good?

s1cab

iTrader: (1)

does this just bolt in place of servo etc ?

rsmark86

iTrader: (3)

and how much did it cost with the braided line ects....

Martin//TwistedTuning

bolts straight on in place of the servo unit

rsmark86

iTrader: (3)

and can you use normal copper brake pipes ect

Martin//TwistedTuning

yup, copper pipes can be used to go from the master cyl's to the calipers, however the drop pipes to the reservoirs are sold separately. alternatively the reservoirs can go straight onto the master cylinders.

mattseries2

iTrader: (1)

no you need braided ones made up with some banjoos etc

This may be a stupid question but does it still have servo assistance yeah, there is still a pipe from it to the manifold?

Martin//TwistedTuning

there is no servo at all, due to having smaller piston master cylinders there is an increase in brake fluid pressure which eliminates the use of a servo, so there would no longer be a vacuum line from the manifold. hth

Karlos G

iTrader: (4)

Oh! Handy for when your engine dies at speed then lol

Martin//TwistedTuning

or running out of fuel in my case

Karlos G

How much better does this actually feel than the stock setup then?
I run 300mm Focus ST up front and Cossie rears, could do with being able to turn the rears down a bit and gain better response all round too.

rsmark86

iTrader: (3)

same as im looking for a front set up with cosworth rears and bias valve but im also thinking about these.

i wanted to buy turbo tonys set up but someone needs to buy the shell (which noones paying 1500 for)....

s1cab

iTrader: (1)

has anyone got a few more pics of one of these?

dave_s2_rst

iTrader: (2)

glad im not the only one here, should be handy if i run into trouble. i think im going to order the compbrake one. would the rear compensators get ditched? Does this pedal have a bias valve attached?

Martin//TwistedTuning

if your still running drums at the back id advise to keep the compensators. when you do a rear disc conversion, thats when you remove the compensators and have a brake pressure reducing valve to the rear or use the balance bar in the pedal box, as rear discs are more efficient and with the compensators will lock up under heavy braking. hth

s1cab

iTrader: (1)

how much would it cost for the pedal box, reservoirs and lines roughly then ? and does it make a big diffrence ?

Martin//TwistedTuning

i havent done the conversion yet so cant comment on what its like, but prices are all available on the compbrake website.

iirc Pedalbox is £140 including 0.65 m/c and 0.70 m/c, reservoirs are £6.50 each extra so would need two of them, and the drop pipes im not to sure on the price of them.

hth

s1cab

iTrader: (1)

so if i bought the pedal box and put the reservoirs directly on top of the master cylinders.. then i just have to join the existing brake line to it? are they easily adjusted? and also what size master cylinder is best? i have focus rs mk1 4pot brembo callipers and 2wd cossie rears..thanks

dave_s2_rst

iTrader: (2)

do the brake lines still operate as diagonals or is it one master cylinder for front and other for the rear?

muz

I bought my braided lines as a kit already made but you can buy all the bits needed from Merlin motorsport. You wouldn't run a diaginal set up with a bias box as the master cylinders are different sizes. .625 for the fronts and .7 for the rears so they need re lining anyway. the reservoirs use M10 fittings.

The bias box doesn't need servo assistance which is also a bonus if your running anti lag

I've also put a Bias valve on the side for the rears incase I need to tweek the rear brakes in the wet etc as theres alot of braking force up the rear of mine and I don't want to keep adjusting the balence bar.

Karlos G

iTrader: (4)

Looks that way yes, the smaller the MC the more pressure it will apply so 0.625 would be the one I'd go for.

dave_s2_rst

iTrader: (2)

cheers muz, making sense now!

s1cab

iTrader: (1)

sounds quite simple ! so basically you remove all brake lines and just start fresh and go straight from the master cylinders to the callipers.. are they easy to adjust?

s1cab

iTrader: (1)

how much did it all come to? including lines.

muz

I paid £100 for the lines ready made off someones car they were breaking and £140 for the pedal box, second hand but never used. I would go for a smaller cylinder for the rears like a .70

rsmark86

iTrader: (3)

im going to look into this aswel i think but if i buy all the stuff for the lines how hard are they to make up ect....

dave_s2_rst

iTrader: (2)

i've made up braided hoses before when i removed the abs, really easy to make up
