Rubber grommets are cheap and spares should always be carried. Usually makes glad hands tighter. Barring the aluminum isn't damaged somehow

Not as fast as u think? U would be better off putting brake pedal to the floor than pulling the knobs.. Pulling the knobs only sets the parking break which is most likely only on 1 axle.. Using brake pedal u have brake power to all axles...But then again it should never get to that point...Coffey, bigguns, Dale thompson and 2 others Thank this.

Didn't I just mention something about that?
The engine shut off and there were no engine brakes, with the transmission in N. -
If you're driving appropriately, the brakes will be cool(er) and therefore more capable of stopping the truck in an emergency situation. If you've been riding the brakes all the way down the hill, they're going to be hot. You're that much closer to brake fade.Freddy57, magoo68 and God prefers Diesels Thank this.

Agreed, popping the knobs is really only if you have a service break failure and what you have left isn't enough. The post that was in response to, his glad hand popped off.
IIRC, a new can has roughly 60 psi of spring pressure. Not a full application but stronger than a normal brake input. That a little drops over time as the spring ages, but not dramatically.
Fleet trucks are the ones that tend to only have one axle of park brakes, and I don't think I've seen a trailer without Spring brakes on both axles. But if you've had a major leak on the service side, the knobs are coming out on their own before too awful long anyways.Dale thompson, God prefers Diesels and D.Tibbitt Thank this. -
And that is probably the reason I was able to stop safely.
Thank you for the obvious.God prefers Diesels Thanks this. -
So why bother to quote my first post then in the first place if you already know the obvious?650cat425 and God prefers Diesels Thank this.

Tankers don't like sudden stops and ya hear a few stories of drivers burning to death or worst a driver burned bad but living and you don't do any jerking movements to that truck. Your right about pulling the knobs if the car had moved or cars up ahead but if its clear and you can slow the truck to a controlled stop using other means you do that instead. I was lucky I had other means at my disposal and more importantly had thought about it beforehand.
That's one of the benefits of TTR for drivers. The chance to talk and think about a problem before it happens so if it does you have options.
When the occasion allows practice downshifting and using the jakes to slow down. I've noticed different trucks handle differently. -
...A dangerous drawback!!

650cat425, Coffey and Moosetek13 Thank this. -
If you do it right even that’s manageable, barring the possible freak mechanical issue that is.650cat425 Thanks this.
