Braking Issues

Yes, application reading for psi is coming directly from brake gauge. Truck has R12 mounted on cross member directly under the 5th.

 

Copy, and thank you all. That will be something to look into, I'll have to see if I can locate pneumatic diagnostic test equipment for purchase.

 

Full agreement with everything you said, and yes, today's autonomous vehicles/trucks are dangerously scary. I had a rental from Penskee for about a month. The truck has the cruise monitor system (CMS or CMS), I can't recall complete the definition, but that thing would brake check out of no where autonomously. Rain, ice, or snow, it's not bias of road conditions or traffic in front or behind, it hammers down. Whether a driver nearly missing their exit, cuts off the truck or approaching bridges and underpasses, the instrument panel flashes red "out of no where", blinking "eminent collision!" sounding like a smoke alarm just went off! Scared the living life out of me. Also did this several times passing in a wide open lane, not to forget, it paces you with the slowest vehicle on the road, so much for cruising these days, the terminator is finally here, say no to A.I.

 

You know, I was wondering if they were the wrong drums, here is why. When I adjust the brakes, the top shoes are always the most out of adjustment, like not even close. Therefore, as the slacks are rotated the bottom shoes hit the drums first, rather then simultaneously top and bottom. I then follow with an additional fraction of rotation 1/4 or 1/2 drawing the top to the drums.

I found that unusual but the fact all drums, shoes and hardware on this unit came worn out, I have nothing to compare with.

You gave rise so something I'll need check into.

Thanks for the reply to all!

Merry Christmas
