Re: Wilwood master cylinder
I have been running a manual Wilwood master with 7/8” bore for 4 or 5 years now. I’m happy with it.
A bit more pedal effort than with a booster, but the previous engine didn’t make enough vacuum to operate the booster. Some day maybe hydro boost and bigger brakes all around. But then I will need larger wheels and then tires …….and….

Re: Wilwood master cylinder
Forgot to add that my truck is also a 72 C10 stock front disk/ rear drum at this time.

Re: Wilwood master cylinder
If you already have power brakes it should be 1-1/8" I believe.

Re: Wilwood master cylinder
I installed a 1 1/8 with a booster on a truck that is ls swapped but has a pretty mild cam. I ended up switching to the 1 inch bore because it took more pedal pressure than I liked to stop.
