Some notes on dual circuit brake M35A2s 

Great info. First close up I’ve seen of the dual circuit system.

Man Garrett ,, 🤩its so good to see you back for a while, you have created a wealth of knowledge and a Library for present and future Military vehicles especially the former models. So much knowledge will be lost but you have made it possible for these old vehicles to keep surviving 💪and giving much enjoyment to their owners and drivers. Thank you very much.💂‍♂

Thank you for this informative video. Always thirsty for knowledge! Even though mine don't have a dual circuit.

Thank you for this! I own one and can testify, yes you can most definitely have a short and a long that’s the way mines set up On a side note When I hit the brake pedal there’s no resistance until about the last 4 inches of the pedal and I have to stand on them to slow down not stop 😂 If I violently pump the brakes I can get better and better braking force. I’m getting ready to rebuild the air packs and get a new master cylinder assuming the majority ot my issues are within those two When I take the service plug off brake fluid comes pouring out.

Cool...thanks for sharing. Nice to see that some of these trucks have dual brake lines and air packs. Too bad the dual line master cylinders are rear and hard to find. I hope someone makes quality after market parts for that particular master cylinder. But in the mean time...I was wondering if these can be converted to the original signal circuits brake system since the signal circuit master cylinders are more available?

Thanks for the info. On single airpack trucks . can you put either long or short airpack on Those trucks.Thanks

I have one great video thanks

I believe that is a MC is made by bosh/bendex hydro-max

Thanks for the drop of knowledge, but my question is, if adding air tool oil to the air pack, how much oil would be recommended to add? I've never added any to mine and no idea if it ever has been done, sure couldn't hurt, lol.

Brakes hydrologic buster

I work for UPS as a mechanic and these master cylinders look just like the Hydromax ones that every UPS package van has. Given Hydromax has so many options I would imagine there's something close enough to work. Do you have the mounting hole measurements? I measured one today for my dual circuit conversion plans.

I see that Boyce equipment has a dual circuit master cylinder on their website. Would that just bolt up where the single circuit one went? Then just add the second air pack and proportioning valve etc.

Man, was not expecting to need a 2nd air pack to upgrade to dual circuit. Any way around this or that unsafe somehow? Have the dual circuit master, guess I'll have to go back and reread what all's necessary.

Have an airforce truck but feels like it has air in lines. Have tried bleeding brakes with no luck. Any ideas on other causes for this issue or just a failure to fully bleed them.
