Brake booster
I have added disk brakes to my 67. How well will It stop without the booster?

Re: Brake booster
it'll stop fine, you'll just need to press harder.

Re: Brake booster
It should, but there's a lot riding on the "IF's"....
The vacuum booster just increases the force applied to the master cylinder. If you are young and strong of leg, you should be able to lock the brakes and scare the crap out of everyone else on the road with you!!

Re: Brake booster
There's no clear answer to your question.Manual discs should work fine.So should manual drums.That is if they are in good shape.Actually drums should have more friction surface and theoretically should be better at stopping your truck but the discs radiate heat away faster and the heat is what causes brake fade.I'm in the process of converting to power discs,mostly because I want a lower stance and I do a lot of driving in heavy traffic.The reduced fade should be good for that.Serviceability is also enhanced by discs.You probably wont see much difference in pedal pressure but you will have better repetetive braking.Hope this helps you.

Re: Brake booster
if you seen mike nutts build he has this set up. it stops just fine , but you do have to make up for the booster with your leg.

Re: Brake booster
No matter what brake style you have " Brakes are only as good, as they can disapate the heat they generate"

 I've replaced a lot of brake shoes and pads on vehicles, but I've never worked on or driven a disk brake vehicle without power. So, I really have no personal knowledge of how much more pressure you would use on one versus the other... |

Re: Brake booster
My 67 Corvette came from the factory with 4 wheel discs and no vac booster system. The braking is excellent and never have experienced any fade. Having driven others with 4 wheel discs and the vac power option, mine give better "feel" and control than those with vac assist - you just have to get used to it and - of course - use more leg effort.

Re: Brake booster
My '71 C-10 came with manual disc brakes. I like the way they feel, but they do take more force to operate.
I can lock them up if I want without any problem, but I like the control manual brakes gives me. My son put power disc brakes on his '70 C-10 short bed and he likes them but they feel a little touchy to me. Danny-Southeast Missouri |

Re: Brake booster
Praise Brake Dyno (website??) has/had kevlar brake linings that they said would put a lot of other braking materials to shame. Saw an article in a magazine about them and they were quite complimentary. Drum brakes that stopped better than any 4-wheel power discs, they said.
