now this adds a new road to travel with the statement "pedal goes to floor and not stopping". if the plunger was oxidized and stuck the brakes should be partially applied; which apparently they are not. or plunger NOT going all the way down to activate brake valve, combine that with only the left rear front wheel acting up! three other wheels ( plus steer axle )should stop unit. I would look at the pedal; possibly remove it , hope alum bracket doesn't break ;clean all parts. hold the phone;;; old school thinking again== is this pedal floor mounted  as in olden days or hang from under dash ?? 

floor mount

"driver side  rear front " stated  would indicate tandem axle , might have a service valve per axle based on being a 2000?? can't recall excessive brake pressure blowing out a service valve.  have seen excessive pressure locking up/slowing down brake application when a cam stands up or jumps the shoe rollers and jams.

brake pedal don't seem to have the pressure it use to have 

it goes almost to floor and not stopping

I was wondering about a pressure valve

You could also have broken friction material off the shoes, or cracked a brake drum.  When the brake drums get worn out and thinner they're easier to blow apart. But I'd expect that carnage would be obvious.

yes took drum off to verify brake are more  then half of new and I adjusted slack all the way around to confirm its not stuck or binding

air the lines switched? the chambers are not isolated on the service side.  one valve should be sending service air to the service side of all of the brake chambers..  

yes sir lines are hooked up correctly

ok had a driver slam brakes in front of me so I had to slam slide duck everything

so now my brakes don't feel the same  takes longer to stop if I can when loaded

so I'm looking things over decided to replace all slack adjuster on back with new from mack 

as I'm looking things over I let air build up and press brakes to get everything adjusted back out 

driver side rear front axle does nothing

brake chamber doest move s cam not moving so I figure chamber 

put new chamber Samething not moving 

there's air on both lines 

where or what should I look at its 2 different valves in line I guess 1 is abs with a plug the other is big valve 

s cam is free not stuck when I press brake pedal it makes a noise can't remember if the noise was there before or after I slammed brakes

any help is appreciated

thank you 

thank you sir 

hey guys any of you have the part number for the oil sensor that's on the top of the oil filter housing 

2000 rd688s e7 400hp

I called my local dealership

4 auto slack and this sensor came up to 730.00

no way 

slacks are 120.00 each there so there is no way this sensor is that expensive

thanks guys

also I did a Google search but get alot if different 1

ran it about 45 minutes to a hr 

I open the cap and put my finger in there at that temperature not hot at all

ok guys got everything apart

took all hoses off from reservoir tank took hoses from top bottom of radiator

took hose from side of motor to transmission cooler 

flushed everything out with water 

put all hoses back on filled it with cascade let it run til it was blowing hot heat inside around 150 temp on gauge 

now I open reservoir cap the water is still cold I can put my finger in the water not hot at all

I'm thinking of changing out the thermostat 

what do you guys think

I figured try the cheapest part first 

or should I just do water pump and thermostat at the same time

thanks guys you'll been a great help

pic of said cooler with big orange hose and 2 hoses coming off the back 

ok guys I said oil cooler 

it's the transmission cooler that runs off the bottom hose on the radiator

my apologies

I haven't had much time to really mess with it but 

I'm going to have to make so.e time I really appreciate you all 

took belts off no bubbles

took drain out of the bottom of the cooler no water comes out of there even refilled it with drain ran it still nothing comes out 

Jojo if your not to busy I'd like to bring it down to you

have a few things I'd like to get you to do to it if possible

ok guys I have a 2000 rd688 e7 . I changed the water and antifreeze bout yr or 2 back .

checked it now it's rusty so I open the drain on the oil cooler nothing comes out 

.

so I pull the thermostat housing and the water is bubbling like crazy ..why I have no idea the truck is cold ..

any help would be appreciated

I have a video but can't seem to load its to large I guess

when my truck did that I just changed the shocks 

problem solved

try to push your wheels from side to side 

shouldn't be able to if so your shocks are bad

mines would get the truck to wobbling scary

Mike, have you put a gauge on the oil gallery to see if oil pressure is good and stays good?  jojo

no sire 

I've just watch gouge and its at 60psi

Sounds like its an intermittent problem.  To answer your question, no. The ECM sees an electrical fault (open circuit). Try leaving it unplugged and see if the shutdown light turns on. Is the malfunction indicator light on? Coolant temp will cause it to shutdown as well. There should be 2 sensors at the rear of the water manifold. The one sensor at the very back of the water manifold is the coolant temp sensor. Unplug it and see if the trucks shuts down.

Hope this helps

I unplug the back sensor truck shuts down 

 

I just did about the Samething as you 

I purchased a excavator 

but I got my gladhand kit from anything trucks 

haven't Installed it yet but seem to be everything I need 

bunch of good videos on YouTube

I just need to figure out the trailer wiring now before the gladhands 

when I unplug the oil sensor on top of the filter shouldn't the shut down light come on  or shut the truck off

sorry 2000 rd688 e7 400

my shut down ligh. comes on randomly and shuts down sometimes not all 

but fires right back up

I've changed water level sensor

water is full

oil is full 

I could really use some help 

I haul asphalt for a living and I'm afraid it might shut down not start back up 

thanks 

ok guys my shut down light got where it comes on when I hit breaks hard at a stop or if I have to stop suddenly

I changed the water level sensor still no change .

what can cause this where should I look 

every now and then it shuts down but only when I'm stopping

both tanks are full 

thanks guys
