Question for the old timers

Yep. My 89 has valve behind the bumper to do just that. Ex logger.

 

That front brake cutout was pretty popular years ago. Lot's of older trucks had that. The reasoning there, is you were, theoretically, better able to prevent a jack knife with the front wheels turning and I believe that's true. My '72 Pete didn't have front brakes, I went 'round and 'round with a rookie Wisconsin DOT officer, who was adamant that every wheel needed brakes. I politely told them, not if it wasn't original equipment, "wait right here, driver",,, hm,hm, hm,, they come back, "take it away, driver",,,man, that felt good.

 

@Oxbow had seen the extra trolly used to control a air axle from cab on trailer and for steer brakes on. Anyone running really air cheater axles put them down beside the seat so they were hard to see.


I wont get into the how to use a clutch conversation.

 

Some how I poorly proof read that. We had some wrecks with trolly for steers for straight line winching. Later to just have on/off switch. That extra couple tires locked down really could make a difference sometimes.

 

Fella I used to work for in recovery work converted a tank retriever into an off road recovery vehicle. Had a big old gas powered Leroi engine as I recall. Anyway, he put a brake lever on each side of the steering column for steering brakes, and that thing needed them.

 

Yea, the switches I am talking about were factory, and just switched the air off, so the steer axle brakes couldn't be used.
We still run in cab switches for our lift axles.

I have never heard that one, I do not know what it was called and sure never drove one, but Mack built a 3 stick rig at one time.

Tri plex. Drove a Mack dump truck pioneering log roads.

 

Duh, I knew mack had the triplexes, should have put them together. lol

 

The "Tri" in Triplex referred to how many gears the Mack auxiliary had in it, not a third stick. Same for the Duplex and Quadra plex, they were 2 and 4 speed aux respectively.

The third stick was only there on trucks with second auxiliary tranny behind the others.

 

Gotcha, I have only seen a couple of trucks with the 3 sticks, and they were old, at least one of them was an old LT I think is what it was called.
