Brakes- Number of pistons ?

[PLDRIVE]

Take your time when planning your brake upgrade (a lot of factors to consider).

Here are few key points (no brake booster).

What is your pedal ratio.
Do u have enough fluid volume from your master cylinders to supply you Calipers??? Try to use smallest master you can that will supply enough volume for the calipers. Not enough volume = NO BRAKES
Use the largest rotar u can (u will gain mechanical advantage)
Buy a 2 piece rotors ( less likely to warp or crack also helps to keeps the heat away from bearings)



This is how u find pressure.

P = pedal ratio
L = Leg pressure in pounds
A = area of you master cylinder
F = output pressure of your master cylinder

P X L /A = F
example 6.0 pedal ratio, 100LBS pressure, 7/8 master

6.0 x 100/ .6010 =998 Now divide by 2 (2 master cylinders) = 499
pounds of pressure applied (based on 50/50 balance bar)

Good luck
