What does the brake booster do? Does it actually add pressure or does it just assist in applying pressure? As in it helps little old lady's not have to press the pedal as hard to stop? The abs will only allow so much pressure anyways right? I'm just asking because I honestly don't know. Maybe you do and it will make more sense to you.

 

The boosters act to push on the master cylinder harder, so both increase pressure applied to the calipers and reduce pedal effort.

The ABS will reduce pressure if it senses a big wheel speed deceleration, like locking up the wheels, to keep the wheels rolling and not sliding.

If it has been proven in setups of similar speed and weight it appears my concerns are unwarranted, which is fine, just want to make sure you thought about it.

 

it helps multiply the pressure that your foot applies. not sure exactly how it works, but when i took my s10 around the block without the booster hooked up it was some what of a bitch to stop. SUPER firm brake peddle. it didnt help that my rotors had about 3-4 years of corrosion built up on them too. i didnt like it at all.

 

That's what I figure most people are thinking it will be like. That's not it at all. That's why the kit comes with the longer rod. More leverage. The factory systems is designed to work with a booster. That's why they're **** without the booster hooked up. The manual brakes don't take near the pressure from your foot to start stopping

 

Same thing with the manual rack. It's a bitch to steer your truck without the power steering pump working right? That doesn't mean it's going to be hard to steer with a manual rack though.

 

Vacuum assisted master cylinders are not designed to be ran as manual master cylinders. Manual master cylinders have a bigger bore and designed to run as a manual master cylinder with the same or as close the same braking pressure as a vacuum assisted one. If it was such a huge deal you wouldn't see race cars with manual master cylinders, the nova goes 160+ In the 1/8th and has no braking issues.

 

i have 2 cars with manual brakes on 70 stang that i just removed the booster on it is heavier to brake and maybe not for a 70+ year old lady but to me its fine.
The other car is a 72 chevelle with a Wilwood 7/8" tandem master Disc/Drum, and i can honestly say its real easy to brake , i can slow down by using my hand if i wanted, intresting thing is that its more linear and you "feel" the car brake more. only thing im going to change is the pedal ratio, manual brake want to travel more so im going to drill a hole lower than the stock position on the brake pedal.

 

that makes sense.

i installed a manual steering box on my s10. it's not "hard" to steer it, but it's definately not power steering. would a manual rack make my s10 easier to steer over the OEM Setup with a manual steering box? i'm thinking about adding power steering back...just so i can drive with one hand on the wheel and the other on my purse

 

It'll turn better with a manual rack after you lose 100+ lbs off the front end lol

 

I have 100% stock brakes on the front of my truck. Even the pads are original, granted my truck has less than 20k miles on it. They are being fed by a manual master cylinder.......and I've had no trouble stopping yet.....150+mph.

I do have strange brakes in the rear with 4 piston calipers. Not sure how much that helps.
