hey all,

just got a 1972 international 1210 345 v8 2wd all drum pickup. It has manual brakes, and I was going to put a booster on it....just found out that there's a bracket that goes between the firewall and the booster.....if I find that bracket is it a direct fit?

Thanx for the help!

 

PS do you always have to look at the pics of the rigs and scroll down to the topic? :unsure:

Blasttruck...To find topics and posts, simply click on "Forums" at the top menu tabs.  You'll go immediately to the subject areas and can find all topics there, including the I-H section at the forums...You can view new content under "Forums" and the "View New Content" tab...Trust this helps!

 

As for your booster installation, you need to find a donor vehicle with the complete drum brake/booster you want.  Everything from the brake pedal, brake pedal pushrod, the booster and firewall bracket and even the master cylinder itself must match a power booster system.  (Some of your current parts will likely match.)  Confirm whether the master cylinders were the same between manual brake and power booster models.  Go to a brake manufacturer's catalog or NAPA's application catalog and compare the part numbers for a master cylinder on a manual brake 1972 1210 2WD truck and a power booster brake model.

 

Once you have all parts needed, make sure you check/adjust the pedal-to-booster pushrod length and the booster-to-master cylinder pushrod length.  These pushrods must be adjusted properly.  The booster to master cylinder pushrod must have the right penetration into the master cylinder's piston.  If the rod is adjusted too long, the piston will not retract fully and can trap brake fluid in the system, causing brake drag.  Of course, the rod must also have enough travel to fully push and apply the piston.  If you need the booster pushrod to master cylinder piston adjustment, I should have it.

Blasttruck...Let me know whether this is a Bendix or Moraine brake booster.  Did you confirm the master cylinder match, and is the power booster master cylinder the same as your current master cylinder?  Are you getting all of the parts, with the master cylinder still attached to the booster?

 

Let me know what you get.  If the master cylinders are the same and the booster has not been readjusted from factory setting, you should be okay.  I can share the master cylinder/booster adjustment method once you determine the booster type and which master cylinder type is involved.

Thanks again Moses,

The guy is sending me the original stuff from his 73 1200. His is auto, mine is manual. I cant imagine that mattering. Im going to use  a new (rebuilt from Orielys) booster and cylinder. The part number is bhh50-3114. Other searches say the same part number as cross reference.

Blasttruck...The rebuilt booster and cylinder, if sold together, should have the proper pushrod adjustment.  (Even if these parts are sold separately but match each other as replacement parts, the booster pushrod should be adjusted correctly.  I can describe how to measure and compare booster pushrod length and the master cylinder piston recess depth.)  That leaves just the brake pedal rod and the pedal adjustment.  The pedal pushrod must align and fit properly on the brake pedal.

 

There are several I-H Scout and light truck specialist sources to confirm part numbers and fit.  Parts and service manuals are available, too.  You can confirm conversion parts fit with your power brake upgrade:

Rule of thumb is to make sure the brake pedal return height allows full retraction of the master cylinder and booster pushrods.  The pedal return stop is adjustable to assure full release of the brake pedal...We can discuss this further once you get the parts all lined up.
