Re: Brakes:Did You Know?
My truck had a C10 booster on it for who knows how long. It worked OK, but it finally gave out one day, I could bearly get the truck stopped. I got a booster off of a '72 GMC 1 ton, made a huge difference. You won't need front discs with a 1 ton booster.

Re: Brakes:Did You Know?
The master cyls are bigger on 3/4T & 1T, but seem to work fine on 1/2T. The early drum/drum booster will work with the 1/2T MC...however, the 71-2 booster disc/drum uses a MC that is unique and not the same depth hole as the 1/2T.
You must run the matching 71-2 MC with the same year booster...and note that the dual boosters do use a matching set of brackets. The 1/2T brackets are not the same and don't space the booster off the firewall correctly. Confused yet? It is a good upgrade...if you don't screw it up!!! The top booster set is 1/2T drum/drum and also drum/disc. The bottom booster set is 3/4T & 1T drum/drum. Notice the differences? I don't have pic of 3/4T & 1T disc/drum 71-2 set, but they are completely different again. If you don't have the correct brackets & MC to go with the booster, you are in trouble!

Re: Brakes:Did You Know?
Which brings us back to my question. Where can I find the brackets? Most of the junk yards around here are picked clean.

Re: Brakes:Did You Know?
Is there a core charge with these purchases? I want to know because I want to go from a std brake disc system to a boostered one, and I would'nt have a core with a booster. Thanks.

had i ordered the reman one, it would have been an $8 core charge, i think. the different suppliers varied on these core charges, though.

With the exception of the starters, altenators, batteries & GM style fuel pumps. Othe than that, NAPA has some good stuff.

Re: Brakes:Did You Know?
i'm still wondering if the 1 ton booster from a '69 will fit a 1/2 ton 69...no one has really come out and said yea or nay yet...as for napa, i've had good experiences from them, and will continue to use them!

Re: Brakes:Did You Know?
regarding the posted pics (and other references i've found for parts) my m/c is not the same. so far i haven't found it in any of my references, either, so i'm wondering if it's correct.

Re: Brakes:Did You Know?
The NAPA booster /mc and the ones from Advance, do not seem to come with the needed mounting brackets or the pedel/booster rod. Please correct me if I am wrong.
The P/N NBB 501011 1 ton dual booster + mc is $ 159.00 plus $33.75 core. That comes to $192.75. Returning my mc will get me $8.75 back. So a total of $184.00 would be spent and I would still need brackets and a rod. So would $175.00 plus $21.00 shipping for an entire dual booster/mc/brakets/rod look like a good deal? That would be a total of $196.00. $12 dollars more than NAPA with the hard-to-find parts included.

Re: Brakes:Did You Know?
Now, would this all work on a half ton 1967 with all wheel drums?

Re: Brakes:Did You Know?
The attached printout says so. I need to do some more research. The mc is a corvette style. The front and rear bowels are the same size. Both drum/drum and disc/disc mc's are made this way. There still might be some differences. Also there is no proportioning valve included so that could be a problem. I was going to try and use my original valve.

Re: Brakes:Did You Know?
You guys are on your own with all this swap-around brake stuff,you know.I believe the brakes were already engineered by GM and work as well as you could need.Is someone experiencing poor braking from a properly functioning stock brake system?Isn`t the booster just an "assist" component and not part of the hydraulic system that actually stops the vehicle?I`m just putting thought to where it seems to have been overlooked,since this has become a booster think tank.

Re: Brakes:Did You Know?
I've got stock disc up front, added disc from an impala SS in rear...
Truck was originally NOT PB Using a 3/4T booster & brackets....MC is from an impala SS. Stops nice but I've always felt that it should be a little better. I'm wondering about my booster since some brake fluid got in it from the previous MC. Is it possible that 1 of the diaphrams is bad, but not the other? How can I tell? Here's the other thing...There's a rubber "boot" between the MC & the Booster...Without that installed, there was a major vac leak & PB didn't work too good. By the way, the pedal rod it pretty SH****Y on the 3/4T setup. I had somebody cut me off...I mashed the pedal so hard I bent the friggin rod! had to make a new one out of a grade 8 bolt & some other materials.

right now i want ANY improvement, the more the better. btw, i got my '72 1t booster today. i'm still at the office, but it looks nearly identical in size/shape/rod length to my 1/2t booster. i'll try to put it on tonight and take pics...maybe i won't need 1t brackets?
