1 inch bore Master with Hydro Boost, will it work?

[hp jnkey]

My 69 has Wilwood 13 inch rotors with 6 piston front and 4 piston rear calipers.
Came with 7/8 inch bore manual master cylinder and wasn't happy with the hard pedal
so I installed an 11 inch vacumn booster and a 1 inch bore Wilwood master but I'm still
not pleased with the brakes. The engine is producing plenty of vacumn, 18-20 inch at idle.

I've decided to go with hydro boost brakes and I'm wondering if its ok to use a 1 inch bore
master cylinder with the hydraulic brake booster.
I know it's recommended to use a 1-1/8 bore master.

Please chime in if anyone has personal experience

Thanks

You should use the proper 1 1/8" bore master.

The previous setup you had, the 11" booster would most commonly run a 1 1/8" as well.

We sell a lot of Hydroboost units and ALWAYS with 1 1/8".

Let me know if you need help on any of it.
