Thinking of going manual brakes on street car, Need some input.

I am not posting this on the Mustang site i frequent because the answer will be bias.

I have a 1995 Mustang GT thats getting a Gen II Viper V10. The motor takes up alot of room because of its height.



Current rotors are 13" up front with 2 piston calipers and 11.25" rotors in the rear with single piston calipers.(Cobra brakes)

I have three options for the brake master cylinder.

1: Get a 1" bore MC and 7" booster. Move it over 1/2" away from the motor. But changing the rear spark plug will be a major PITA with the booster in. I will also most likely need a vacuum canister, due to my cam.

2: Relocate the Master cylinder and 7" booster to the inner driver fender. Lots of little modifications and levers needed.

3:Manual brakes with this kit.

So my favorite option is the manual brakes. Looks cleaner and is supposed to have a better feel if done correctly. I have driven old cars with manual brakes and they were not that bad. Drove a 73 Camaro(Road Racecar) with Manual brakes and disk on all 4 corners. It was barely firmer then brakes running a booster. I liked it alot better, as it didnt take alot of effort to move the pedal and it stopped better then most cars I had driven.

That experience makes me think i could maybe get the same effect.

How many guys are running manual brakes on the street? Opinions, thoughts?

I removed the power brake booster on my '72 Nova, disc front/drum rear, and stopping is the same. Only difference is it takes a slight bit more pedal effort and slightly longer pedal travel, but like you have said I feel it has a better "feel" for what the brakes are doing.

I did it just because I was using cams too big to run power brakes, even with a reserve can.

I've done the same with an S-10 with 4 wheel disc, good stopping power there also.

All a power brake booster does is reduce pedal effort, it doesn't do anything to help braking power. Good for old folks and soccer moms.

p/b's

as nova mentioned of the increased peddle pressure.. on my bucket we normally use a 7/1 ratio. u may need to increase that to 8/1 for added help.

There is a different location on the Brake pedal on some cars for the master cylinder pushrod for power and non power brakes.Some cars have a different pedal some 2 holes.

I have no power steering, so no hydro boost. I am going with a Pinto/Mustang II quick ratio manual rack.

I originally was going to use hydro boost but I didnt want potential leaks or any other problems that would be associated with it.

IMO- its cleaner and less hassle without it. And less weight.

That manual brake kit I posted comes with a pedal lever that has a different geometry. So its easier on you to push the pedal. Also the pedal itself has 6 mounting positions that supposedly helps you "fine tune the leverage".

Thanks for your input guys. I didnt think the booster was anything but an aid in braking. Most people seem to think if you take it out you lose alot of the braking power.

Sounds like you have it all figured out with the kit, let us know how it works out.
