Take the front Q2 valve apart and see if the nylon ball is busted or if the spring is bad. https://youtu.be/GG9H5Zc52qM If you have replaced it already then swap your drivers side middle and lower line with each other. Sent from my SM-G935P using Tapatalk

Ok, So for this afternoon I replaced the Quick Release valve since it was just easy and quick to see if it worked. No dice. So I went ahead and replaced all 10 service diaphragms and also the 4 spring diaphragms since I had em off anyways. None of them were damaged other than some slight...

Power comes in to the gauge and goes out of the gauge to the sending unit. Sending unit is the ground and the resistor in it makes the temp read on the gauge. More than likely the unit just isn't grounding due to rust or some crap in the threads.

It is shorting out somewhere between there and the temp unit. It usually tends to sit right at the 240 mark even though the engine is only at 180. I just haven't replaced the wire, it could be as simple as the unit not grounding as well.Also strange that If I swap both wires off the gauge onto...

Alright well so far today I replaced the Q2 valve on the front. This now allowed air to be drawn from both tanks when I hit the pedal and it vented out thru the intake. After doing this the air pressure dropped very quickly from both tanks 120psi to 0 in a 10 seconds. Next I Replaced the...

Ok after Q2 valve was installed it was a very quick drain of both tanks. Installed a good used treadle assembly and i still have the same problem. Not as fast of an air loss with the old treadle assembly but still will not hold at with brakes applied and still hissing out the intake. Sent...

Treddle valve will be the next step. Replaced the Q2 and it dumps from both tanks now rather quickly. https://youtu.be/jMzrNgg_keU Sent from my SM-G860P using Tapatalk

Will do. I will add that my abs light as always been on. And brakes would lock up if applied hard. Force the pedal to the floor and they wont lock up at all. Light is still on. Sent from my SM-G860P using Tapatalk

Yea especially all the sudden. I am not suspecting them at all to be bad. . Just took this video. No brakes cages. E brake off. Doesn't take long to build pressure. But while driving and I come to a stop I tend to always have a brake squeal from the rear. I do not have it now. FFW to about 1...

Yea at the moment it is slow. I mean I don't use my brakes much anyways. Letting the downshift bring me to a stop almost. Especially in traffic keeping distance. And I am never in a hurry so. I don't tend to use them very hard but yeah here as of today pedal to the floor and it slowly stops...

I was thinking the treadle cause when my emergency air gets low 60psi or so my secondary tank does not lose an air at all at 120+

It is firm for the first few seconds of the pump then it fades off and when it hit bottom I have no pressure on it and It is spongy then.

Reviving this thread. Working on a problem that just started. Going down the road and hit the brakes and my air pressure drops about 25 to 30psi on the emergency tank. Secondary doesn't move. Can hear it coming back out of the intake tube when I pump the brakes when I am sitting still. I do not...
