Brake monitor alarm
This maybe way out in left field but lets see what others think . My instrument panel will provide a warning signal audible and visual if the turn indicator is left on for an extended period of time and I think it is a great idea and has alerted me a few times. Now since we all know that there is a code recorded after the brakes have been actuated for more than 2 minutes with the vehicle moving why could there not be a similar alarm to alert us to this situation as well. Maybe it could be as simple as a small indicator lamp that comes on with the brake lights.
What do you think?
Rick

OK so i guess this is a bad idea 45 view and no replies thanks to all that looked.

This is a good idea if your already monitoring OBD2 codes.
Try sending it to Scanguage or VMS producers. To them it's a software change. To anyone else it's a whole system development. One that can't be done in the garage by a normal person at least.

Why would you want a 2 minute delay in the warning. If you want a red light on the dash to warn you that you are applying the brakes, just run a circuit off the brake light switch to the dash warning lamp.

Exactly Diesel thats what i suggested as the simplest way

The 2 minute thing is maybe something that could be incorporated into future builds and would coincide with the existing code setting feature and would not be as annoying as a light that comes on every time the pedal is depressed. I am sure the simple circuit could also have a delay timer build into it very easily without having to be part of the ECM circuity but would not provide the movement component so if you were stopped with the brakes applied (stop light) it would come on unnecessarily.
Just thinking out loud I guess.
Thanks for the replies
Rick

If you want a 2 min delay use this time delay relay to light a light on the dash or even add a buzzer. Something Workhorse would have done if they knew what was comming.
Connect the brake kights to the input.
Amperite - 12D1-100SST1 - Allied Electronics
And here's the data sheet.
Cost about $30.00 plus wire light and resister.

Thanks Dick that will work for sure . Might be a good winter project. The only problem I see is it might tell us something we don't want to know .

Does'nt 2 minutes sound like a long enough time to heat up the rotors pretty good? It certainly never takes me 2 minutes to stop the MH and on long mtn. grades, to maintain my desired speed, I only stab them for maybe 1 to 3 seconds.
2 minutes of steady using the brake is a long time IMO, You could rub sticks for 2 minutes and start a fire, could'nt ya?

Max, I follow the same mountain braking method, only I use 5 seconds.

Max the reason I picked 2 minutes is that is the time that is already built into the existing system that sets the code in the ECM ie: 2 minutes of brake actuating and vehicle movement and that is one of the items that is looked at by the SC when determining the cause of brake component failure so actually WH picked the time.
I totaly agree with you that 3 seconds to 5 seconds is sufficient time to slow the unit down. Maybe we need a variable timer? or maybe we do not need any more gadgets just common sense.

Brake Temperature Alarm
I have posted this before but some that have joined this forum recently may not have seen it. This is what I have done:
Workhorse Chassis Brake Temperature Monitor
It is a pretty extreme solution but it works. It is set to sound an audible alarm if the temperature of the backing plate reaches 400 degrees. That has happened a couple of times since I installed it. Both were in conditions I think may have indicated a dragging caliper. Both cleared themselves after going to limp-along mode and allowing them to cool but without the alarm I may not have caught it before serious damage was done.
For a easier solution consider the 4-channel monitor referenced at the end of the linked page. It does not have an alarm function. There may be similar products that do but I do not know of one.

I noticed on the website below there is a 12volt version of the controller. Have you seen this? It appears to be the same as your 120v version.
If you have a chance maybe you can take a look and see if it is the same.

I mjust be missing something. Using the brake light switch (which is attached to the brake pedal) as a warning for a sruck caliper can't work. You will have released the brake pedal and the caliper is still stuck. No warning!
The temperature solution seems effective, if slightly heroic.

Actually the temperature monitor will serve a purpose after the "real" caliper replacements. It can warn you of a dangerous situation when going downhill
and give you time to either pull over if possible or downshift to slow down before toasting the brakes.
