Re: Why not drill the fire wall for brake booster?

Having the booster out a ways from the firewall a little like the CaptainFab bracket does would have decreased the angle of my push rod. With that I may have been able to use the hole I drilled 1 1/2" lower on the pedal arm and also a smaller bore master cylinder.

It looks cleaner with the booster next to the firewall.

I really like having it back out of the way as much as possible.

Re: Why not drill the fire wall for brake booster?

Thank you Rocknrod. Most people just don't understand the importance of the booster/master assembly being bolted directly to the pedal bracket the way GM designed it to be.

If no one changed anything everything will still be stock nothing will be custom.

Re: Why not drill the fire wall for brake booster?

Here is my 2 cents. I have a 1963 inline 230 in my 1963 truck. I found a brake booster that would allow me to keep my 1963 factory air cleaner. The new brake booster with disc/drum MC was $99 delivered. You can see the complete installation process - LINK HERE TO MY BLOG POST.

I used the CaptainFab bracket because it still keeps the engine bay looking clean. I'm very pleased with how the brakes perform and how things look clean inside the engine bay.

Re: Why not drill the fire wall for brake booster?

Captain, I have access to a power booster bracket from an original 66, If I get a master say for a 71-72 do you know if I can make that work ? I have already switched over to a dual master for a 67 on my 66 C20 but plan to do a crossmember from either a 71 C20 or a 79 C20 ( I have both).

Re: Why not drill the fire wall for brake booster?

The original '66 power brake booster has the long intermediate pushrod for a master with a deep bore in the back of the master cylinder piston. The '71-'72 master has the shallow bore. So in short, no that will not work.

Capn Fabs bracket doesnt change the factory mounting holes and as you see the factory uses the bracket inside the truck for strength.
What booster are you using?

I know this is kind of old, but very nice write up with photos.

Re: Why not drill the fire wall for brake booster?

Hey Captain, we talked before about putting a dual chamber master on a truck (66) with factory power brakes. Wouldn't it be possible to experiment with the rod length using say a 67ish master? I definitely agree with your idea of using the factory holes for attachment versus just drilling through the firewall.

Re: Why not drill the fire wall for brake booster?

Or maybe just remove the booster and use a 67 master? Seems like a cheaper easier route while still being safer

Re: Why not drill the fire wall for brake booster?

A '67-'70 master will work if you are staying with 4 wheel drum brakes in either a power assist or manual.
