Great video, I used to replace Hydravac units on F600 and C65 medium duty trucks. I've seen those plastic air filters under the seat. They usually got beat up pretty bad, then the rag someone left under the seat would get sucked into the broken filter. The complaint was usually the brake pedal is rock hard and the truck won't stop. We had many shops in our area that would rebuild them along with clutches, reline brake shoes, rebuild alternators generators and leaf springs. Florida Brake and Clutch, closed down over 20 years ago, Colson Auto Electric same thing. Tampa Spring is still in business and so is EBS Automotive they rebuilds generators, alternators and starters. I used to like going into the rebuild shops because they would custom build something for you if you asked.
What you said at the beginning is one of the things that make your channel so great , the "L122 Coleman conversion is your daily driver " , Thanks your videos are great !!!
Great video! Brings back a LOT of memories growing up on my grandpa's farm. He had a 1939 IHC 2 ton flat bed that we hauled hay on and his personal truck was a 1947 IHC 1/2 ton flat bed. I recently got information of the possible location of the 1939 truck. It's several miles from me so when I have some time during the week, I'm going to check it out. I've been unsuccessful in locating or learning the disposition of the 1947. I learned to drive on that 1939, believe it or not. By the time I was 14, I was over the crew hauling hay to the barn and I drove that truck many miles. Usually wide open to the horror of my crew! Of course at 14, I had no concept of fear! All his tractors were IH as well. 100% IH farm operation.
A few years ago one of my friends took a vacuum assist alternator off of a Nissan Patrol diesel and installed it on a Ford F100 and promptly wrecked the booster brake unit. He didn't install a check valve. Thanks for the video.
🎉very informative you do a great job explaining. Question so when you hit the breaks you get an initial boost, then the vacuum equalizes and then the breaks are working like normal breaks?
That's a really good question, the vacuum actually recharges very quickly. You can pump the brakes with a Hydrovac and you'll have power brakes throughout. When the brakes are applied the vacuum even builds up behind it, if that makes sense. I'll be sure to show that in a drive-along in the followup video. Another thing I should have explained is that both sides of the diaphram are in a vacuum before the pedal is depressed, then when the pedal is pressed- one side has atmosphere and the other remains in a vacuum. Atmosphere is never on both sides of the diaphram, so it is never actually equalized. In the most basic way: atmosphere and vacuum are continually fighting over the position of the diaphram, if that makes sense.
I definitely have a few I could rebuild and I'm about to start filming how to add a full flow oil filter on a GRD, so a rebuilt oil pump would be a perfect parallel video to that project. Thanks for the suggestion!
I sent you a message through your store a few days ago about some parts not sure if those messages go through to you, tried accessing email via UA-cam with no success

Awesome stuff, Binder stuff is not easy to find. Great work
Picked up an r140 4x4 last year. Your videos have been so helpful. Thank you!

Awesome video.....audio was just fine.

Hey great video, this was extremely interesting. Thanks for keeping this knowledge alive!
Nice work. Sweet truck
Awesome video! I’ve always wanted to install one of these boasters on my power wagon
Another great video, keep it up. Can’t wait to see your next big adventure.
BSI (brake systems inc) in portland oregon does all ours and they are good to us. Good vid!
Thanks, Dan! I’ll put them on the list. See ya at Sierra Fall Rallye this year?
@@BareKnuckleBinder not sure. We aren't doing any shows this year, but may jump down for the Saturday.

i need a 47 kb2 oil pump repair video before I screw up another repair.
I definitely have a few I could rebuild and I'm about to start filming how to add a full flow oil filter on a GRD, so a rebuilt oil pump would be a perfect parallel video to that project. Thanks for the suggestion!
Looks factory. Sweet. --Doozer
Low Buck Garage is familiar with the Hydrovac
Awesome videos!
Hey buddy the hose does goes from the carburetor to the bendix hydrovac there is a nipple on back of hydrovac where do the hose from that nipple go to
With a single circuit master cylinder don't you need a cable operated emergency brake?
Not on these trucks. They have a driveline lever-operated hand brake.
@@BareKnuckleBinder as long as there is a mechanical back-up. It's hard to believe old cars came with single circuit hydraulic systems!
How did you know I was looking at the gear box?
I could feel it. Retroactively. Through the camera.
