Anyone convert to manual brakes?
#1
As I kept modifying my engine for drag racing I am at a point where I dont have enough vaccum for power brakes, about 5-7 inches. I thought of adding a reservoir but I dont think it will work anyways.
I also saw one power brake swap using the power steering pump to power it but it looked complicated.
Anyone try a good manual brake master cylinder with good results. I was thinking of converting the rear to discs and maybe upgrading the front dics and then getting like a Wilwood brand master cylinder and adjustable prop valve.
Just trying to plan out the "stopping" side of the project since I have only concentrated on the "go" portion of it.

Thats what I'm going to be doing with mine. It will have four wheel manual disc. I have yet to buy my master cylinder so keep me posted on what you find and I will do the same. Dodgy

Here is a site I found when I was doing my brakes. Mine came manual and I wanted to keep them that way but with a little more stopping power. And when I was choosing the cam I didn't want to be limited by the vacuum necessary for power brakes so manual was the way to go. It is hotrodsusa.com then click on Tech, then Brake Article.
He explains the parts, what different sizes do what, volumes, pressure needed and lost when not using a power unit, pedal choices, etc. Very informative. Hope it helps.

What about an external vacuum pump, they runoff the battery and provide all the vacuum you need for accessories.

I looked at that option also but for me did not look like the way I wanted to go. But that is a very viable option.

I thought the vaccum pump may be too loud, and current thirsty.
I already have electric fans and Elec fuel pump.
I still have AC in the car and it works fine with the litle bit of vaccum that I have.
Thanks for the link, I will check those out. In the meantime dont get in front of me I cant stop......

The system that uses the powersteering is called Hydroboost. It is used on all Humvees. (H1). It is not all that complicated.

This is a start to finish install of a system on a chevelle.

One drawback is the systems are quite pricey.
