Power Brake Booster Adapter Bracket

[Captainfab]

All of my booster brackets now come with slotted booster mounting holes to also accept aftermarket universal boosters with the 2-3/8" x 2-3/8" center to center mounting studs.

I need a vacuum boost bracket for a 64 and a hydroboost for a 63.

[Captainfab]

I will send you a PM.

Hi John, I'd like to get one of your powder coated booster brackets for my '66, please.

Hey Captainfab, I'm looking to change my factory '66 brake master cylinder to a vacuum boosted unit. (still have drum/drum)
Will I need one of your brackets if I purchase one of these LMC kits?

Thanks for any guidance!

[Captainfab]

If you want the booster and master assembly to be installed correctly as the GM engineers designed, then yes you will need one of my booster brackets. With a drum/drum braking system all you need is a '67-'70 booster and master cylinder assembly and one of my booster brackets to correctly and securely mount it to your firewall.

So I would need a master cylinder and booster from this page correct?
If I buy that setup then I would also need to find a proportioning/combination valve to route the two lines coming out of the new cylinder, correct?
The previous kit I linked included a combination valve, this one does not.
I've tried researching this prior to asking potentially dumb and/or repeated questions but there are myriad paths.
I just want as close to bolt-on as possible. I understand there will be rerouting of the lines, but I do not have the ability to do any welding or fabrication.
I appreciate your help man!

The booster and master cylinder can be purchased at your local auto parts store. However if you do not have the means (or know someone that does) to lengthen the booster pushrod, you will have to purchase one of the aftermarket universal boosters. With a drum/drum brake system, you do not want nor need a combination valve. All of the power brake conversion kits I have seen from the big name parts suppliers are for either disc/drum or disc/disc braking systems. And what they are selling is a universal booster with universal booster brackets that require you to drill holes to bolt it up. And then it is not really securely attached to the pedal bracket.

Ok, here's a pic, finally figured it out.

[JasontheBeaver]

Ok so in summary...
I go to the Napa store across the street and order a master cylinder and booster for a '67 c10 pickup, and I also order one of your brackets.
I'll also need to order a universal push rod because my existing rod is too short (lol).
Does the new cylinder have one outlet port like mine? If so then it's just a matter of running a new line from the port to my tee.
If the cylinder has 2 outlet ports then I'm assuming I remove the tee and run 2 new lines to connect to my existing ones.
Am I on the right track here?

[Captainfab]

Yes you can simply buy the booster and master locally. You can buy a universal brake booster pushrod, but you do not have to. If you know someone that can weld or thread, the booster pushrod and your original pushrod can be cut to length and joined together by either welding or threading and using a coupling nut.

It really is a good idea to split your brake lines and convert to a dual reservoir master cylinder. That is a much safer design. There are a thread or two here all about how to do that.

So you know my next question... is the new '67 master cylinder that I'm going to buy a dual reservoir model? If not, then it sounds like I need to do further research to find one that will fit this setup.

The '67-'70 master cylinders are of a dual reservoir design.

I’d like to order one of these brackets! Could you PM ordering info to me? Thanks!

[First c10]

Hey John,
I have a few questions.
First, What is the reason GM used the longer bracket with the pivot or linkage?
Second, To use your bracket I will need to remove the bolts that go through the brake pedal assembly that go through the fire wall?
Third, How does the direct push rod to the brake pedal affect the braking or the feel when braking?

Thanks Scott

[pdxhall]

thanks, I'll be in touch

I assume GM went with the bellcrank assembly to change the pedal ratio to one better suited to power brakes.

Yes you will have to remove the bolts attaching the pedal bracket to the firewall since my booster brackets use all of those attachment points just as GM designed it to be. This is a very important criteria that many people overlook or don't seem to care about. Automotive brakes is not a place to cut corners.

If you connect the pushrod to the original manual brake pushrod hole in your brake pedal arm, your brakes may be touchy. If so, just drill another hole in the brake pedal arm 1" lower and try that.
