    How much worse are the brakes on a 70 Camaro, power brakes compared to manual brakes? my engine is only making about 7 inches of vacuum, so the power brake booster isn't getting enough vacuum to assist the brakes. anyone have manual brakes on a Camaro? what is needed to change it to manual brakes? thanks!!!

    I have the same problem. I've been gathering parts to do a hydroboost swap. All I have left to build is the mounting bracket.

    I run C5/C6 disc brakes on all 4 corners of my 81-z with a manual master cylinder...
    if you pay close attention to pedal geometry they require very little effort.

    I also love the fact I get a lot more pedal feedback than running power brakes.

    Our car came from the factory with manual front disc brakes. Car has no problem stopping and the brakes have a nice feel. Originally thought I'd add power brakes - but decided against it.

    The master has a different size piston/bore.I think its 1" for manual,and an 1 1/8" for power.

    I have manual brakes on both of my 71 Camaros.

    It isn't a bad conversion using factory parts.
    You need a manual MC that has a 1" deep hole in the piston so the pushrod can't fall out.
    You have to use an aftermarket adjustable pushrod.
    You will need to remove the brakelight switch and swap the holes that it was in. You'll move it to the upper hole. The pushrod will go in the bottom hole..
    The holes are a different size, so you will need to do some fabricating.

    The brakes are not hard to push.

    Easily slows the car from 120 mph blasts down the quarter mile.
