Quick Question On Disc Brakes

[Carbajal]

I'm going to install disc brakes on my truck this weekend. Want to go with non-power brakes. Will this master cylinder work or do I need a different one? Thanks for the help.

You need a different one and a proportioning valve.

^^ Yes. And IMO, you also need a vacuum booster. It takes higher line pressure (meaning greater leg pressure) to operate disc brakes than drum brakes.

That master will work, the only thing is you will have to refill the fluid down the road as the chamber is smaller. It's a 1" bore which is the same as the proper disc drum master so there is no difference in any pressure. You need a prop valve if the rear brakes lock up excessively before the fronts. All a booster does is give you assist in pushing the pedal, so you have to do more leg work with manual, it's mostly a personnel preference. You do not have to have a booster just because you have disc brakes. I prefer a booster on a heavy vehicle.

the non-disk brake masters have internal proportioning built-in in the way that the ports are uncovered. You need a disk brake master cylinder, and, at a minimum, a disk brake distrib block/prop valve. It doesn't HAVE to be an adjustable one - the factory ones weren't. If you're installing an aftermarket setup, then you probably should install an adjustable one - if swapping in factory disks, then a factory block/valve will do.

I do concur with the comments above - I'd highly recommend a booster setup, you won't regret it. But it is not required.

Also, keep in mind that disk/drum setups used 1/4 and 3/16 brake lines, whereas drums used 1/4 lines all the way around.

I use a non power brake kit I got from performance online. The kit was in my opinion a great value and they work great. I believe you can buy parts individually from them too.

Thanks for all the info guys. I really appreciate it. Im going to check online for a MC and prop vaulve

I just did front discs. I bought the CPP adjustable port valve and 1972 Master with no booster. Boosters are ugly and over rated, you dont need it.

15" steel rims rub on the side of the caliper just so you know. have to grind the corner off. Or get 17" plus rims

I drove my truck with non power drums for about 6 years. It's had power disc for the last 12. If I ever buy another 67-72 and it has now power drums or discs it's getting converted to power. It's cheaper to add it now than later. If you go with the factory style booster, you'll also need the bracket and correct pedal rod.

I converted my non power disc 65 mustang to power discs, and there is a minimal difference in "leg effort," it almost wasn't worth it, HOWEVER, I'd consider the "leg effort" in the C10 to be much more significant with non power, and therefore, worth it.

My clutch is 100 times harder to push then the manual brakes. Not hard to push at all. 60 lbs woman might have troubles..
