bias pedal box which cylinders?

[glenbo]

can someone help please which cylinders go where,i got a .75 and a .625 which is for the front and which for the rear

[BIG G]

0.75 front

0.65 back

[Tom]

now i'm going to disagree and say smaller to the front - also depends on what brakes you've got and also you will need to set the length of the rods on the masters too

[BIG G]

Well you would but i know what im on about ish

[Tom]

i have been through this a lot and a smaller cylinder gives you higher pressure than a bigger one in the same movement.

 

you need higher pressure at the front than at the back but you do need to offset the rear cylinder a little (shorten its rod) so both move equally when the balance bar is at 50% still giving you more pressure at the front

 

 

 

over to you mr G

how much do you shorten the rod?do you have to

Yes you will probably have to shorten the rod but every brake set up is different so you will need to probably fit it and try it then adjust accordingly

While you have the balance bar off the car make sure it is nicely lubed up because it can be a bitch to turn when in situ if not nice and free i know cos mine was a bugger

also check on the rally design website for a howto feature on seting it up properly with the correct clearances

iirc mines big one to back small to front, 50/50 is good en on balance bar

floating mondy calipers up front and capper 2.8i drums on rear =)~

same M/C's

[Tom]

i spaced my rear cylinder off its mount by 3 washers and shortened the front rod a turn or two (proper twat of a job in situ)

[M.Bird412E]

It is 0.625 to the front and 0.70 to the rear if you are running drums and 0.75 if you are running disks on the back.

 

Smaller cylinder moves less fluid but gives more power, if you put a 0.75 to the front the brakes will be like standing on a block of wood you will have hardly any stopping power there at all.

smaller for the front!
