Re: 1930 boat tail speedster from a rough starting point

I talked to Eric a Wilwood technician about my design and my plan is solid. The master cylinder with a 7/8" piston will be good as long as the pedal ratio is 6 to one. 7 to 1 will require a 15/16" piston. I have to go measure the distance from the middle of the pedal pad to the pivot shaft and the distance from the middle of the tab off of the bottom of the pedal arm to the pivot shaft and see what the ratio is. The rotors, calipers and brake pads are good to go. Listed below are the Wilwood part numbers I'm going to use.

Rotors 2 x RH. # 160-9787
Rotors 2 x LH. # 160-9788

Calipers front
RH. # 120-11778
LH # 120-11779

Calipers rear
2x #120-12501

Brake pads
# 150-8855K

Stay tuned for the master cylinder part number
