Need some help on selecting the correct master cylinder sizes for my pedal box.

Cylinder will be AP short body cylinders.

Specs are

Pedal Box - Tilton with 6.22:1 pedal ratio

Front brakes - Evo 8 Brembos

Rear Brakes - Evo 8 Brembos

Clutch - AP 4 Paddle with heavy duty cover.

I was thinking .625 for front brakes and .70 for the rears and clutch.

Can anyone confirm this or offer any advise?

Cheers.

 

.7 front
.75 rears

 

Cheers, Mark. Nige has also told me the same. What would you recommend for clutch? .70?

 

I am using a .075 with a 5.5:1 ratio but have a long peddle travel to get in gear not to bad to change whilst driving,

 

what size is the slave for the clutch?

 

14mm metric AP only.

Don't mess about, that's what ive used on my twin and triple plates, I can press my clutch down by hand.

 

Forgot to mention that it a Hyundai Slave which are apparently 0.81 (13/16") which is 20.6mm metric.



To be honest, I bought it before I realised these things need properly speccing and it might be unsuitable for me? I'm not sure. I just needed a clutch slave and thought it looked quite neat an OEM-looking.
