Re: Power Brake Booster Adapter Bracket

How did you guys get your power brake booster mounted to this bracket? I purchased a 9 inch Tuff Stuff booster and there is little to no room to get to the nuts that attach the booster to the bracket?

Re: Power Brake Booster Adapter Bracket

Are the studs on the booster too long?

Yep the studs were long and created problems, but I ended up creating a tool to get them tightened. I cut down a 9/16 wrench to shorten it and was able to get them tightened. I didnt want to take the booster off as I had all other bolts tightened down already and didnt want to yank it to cut the studs.

I had thought about doing that but I am not sure if cutting the studs would have helped in my application. Thanks!

Re: Power Brake Booster Adapter Bracket

Captfab, I purchased one of your brackets for my 60 suburban and hung 90 c1500 booster and master assembly, I believe, on it. CPP brakes up front SSI valve and drums in there rear. My cammed sbc350 truck stops great!

A buddy bought a 63 with a 6.0 ls motor with discs up front and drums in back and keeps fighting a spongy/ soft pedal. He's gone from a dual 6-7"booster to a dual 11" booster and no difference and even changed to Dane master I have and wilwood valve.

I keep telling him to order your bracket, but it's been 3yrs since I ordered and thus I can't recall what exactly he gains by doing this. I believe it fixes the angle.... is there more to it and could this this likely fix his issues? Also, which bracket would he need. Here only has 2 holes on firewall, so he'd have to drill two more.

Re: Power Brake Booster Adapter Bracket

Your buddy's issue could be caused by the valve in the prop valve partially blocking one side. It could also be an issue of the booster pushrod being in the original hole and not 1" lower as most people do. My booster bracket does mount the booster/master at a slight angle which keeps everything a little more in line when you move the pushrod down 1" on the brake pedal. All '63-'66 trucks have 4 holes in the firewall and the corresponding threaded holes in the pedal bracket. That is the other advantage of using my booster bracket. All of my booster brackets utilize all of the available factory mounting holes to provide a solid connection between the booster/ master and the pedal bracket on the inside. Most people do not under stand the importance of this.

BTW this for sale thread is for the '67-'72 standard booster bracket. The for sale thread for the '63-'66 standard booster bracket is here.

Thanks for the feedback. I wondered if I had the wrong thread after I posted. Hopefully, he'll just order the bracket, this issues been plaguing him for several weeks now. He bought the truck this way.

I know I questioned a lot of this stuff when I did mine because I was starting from factory and gutted it all. As I said mine works great now.

Re: Power Brake Booster Adapter Bracket

I have a power brake booster adapter bracket on my 1968 Chevy C10 shortbed and i also installed a brand new Tuff Stuff 9in booster TFF-2224NB.

My 68 is originally a 396 engine with 400 turbo automatic and column shift. There is a very long shift rod that is attached to a shift lever down near the trans then up near the power brake booster to a lever there.

The problem is that long rod is hitting the bottom of the booster and will not allow me to shift at all.

I knew some where having issues with a shift lever but a smaller booster was supposed to fix that...but this is a long rod hitting the bottom of the booster.

The rod looks to be a factory type of assembly but I could be wrong.

Anybody else run into this issue and what you did to solve it? Thanks!

Re: Power Brake Booster Adapter Bracket

Can you post a pic or two so we can visualize what is going on?

Re: Power Brake Booster Adapter Bracket

Here is the rod that i was referring to. It is the long rod that is hitting the bottom of the power brake booster. It seems that even if I cut the rod the lever the rod attaches to would also end up hitting the bottom of the booster. I will post another angle as well from up above

Re: Power Brake Booster Adapter Bracket

The shift lever is in drive right now, but the shift rod is hitting the bottom of the booster and will not let me shift into Park Reverse or Neutral.

If I cut the rod or installed a shorter rod so the lever could move up then I think the lever would end up hitting the booster as well. I say this because when you look at the shift detent plate that the shift lever slides against you can see the small hump on the plate which separates the reverse and park position. The park position is just to the right of that hump as seen in the pic and the reverse position is to the left of that hump.

I am trying to find a shorter rod to install so I can actually find out if that lever will also hit the booster when a shorter rod is installed. I dont want to cut my factory lever.

Re: Power Brake Booster Adapter Bracket

I'm just going by what past '67-'72 customers have told be that a 10" or smaller booster is needed with a column shift.

Yeah that is why I purchased the 9 inch booster in the pic.

Re: Power Brake Booster Adapter Bracket

I removed the rod and sure enough the lever also hits the 9 inch booster.

Re: Power Brake Booster Adapter Bracket

Sorry but I do not know what is different about your truck versus what others have done. How much more does the lever need to move after it hits the booster?

Maybe 1/8 to 1/4 of a inch more.
