Brake master cylinder size

[danielruhe]

I am curious what I should use as a master cylinder bore size.  Im fitting a Wilwood's pedal assembly with dual brake master cylinders in my conversion.  I have Wilwood 4 piston brakes front and rear.  and I have a 7/8 bore slave cylinder for the t5.  What master cylinder bore size should I used for the brakes (one for front and one for rear) and for the slave? I also want to keep it all manual brakes.

Hello Daniel, I would check with who ever you bought the calipers from. They should have an idea. Good luck and keep us informed on how you do.

Agree Wilwood tech should be able to advise.  They may want to know the vehicle weight.  For reference, my car with about 12 gallons of gas is 2419 lbs.

Ok guys will do! I think Wilwood's most likely will be the best resource.
