I need Brake Boost.

Hi,
I built the engine recently. Because vacuum is a little, the engine cannot satisfactorily move the brake booster. I am examining two methods.
1.The electric vacuum pump is added to the current system.
2.The vacuum booster is exchanged for the hydraulic booster.
Which do you recommend?And, please teach me the reason.

Thanks,

Yuichi

good Morning,

The Hydraulic booster would be the preferred method. Awesome braking power and you wont have to run any external vaccuum pump and you always have power brakes without the worry.
