I have a 92 CL-700 with an E9-500. The engine brake works great when the engine isn't super warm, (i know, not the time to be running the jakes) but when it gets to normal operating temperature, it won't turn on. When I let off on the pedal, I can hear a buzzing coming from the dash but nothing happens. Occasionally if I leave it for a long time, the jake will eventually come on, but not always. If I leave the truck idling with the switch on, the jake will randomly come on and the engine will sound like a drowning water buffalo. It's a great truck other than that, leaves all our other ones in the dust, but I'm scared that I'm gonna end up with an unwanted hood ornament made by Ford, GM, or Chrysler if i can't get this brake working.
Hi All, I have a coupng le questions #1 My truck has a dynatard engine brake. I've had numerous problems with the Micro switch on the accelerator linkage. In my opinion Mack didn't use a very suitable switch for its application. I straightened this out with a much higher quality switch. Now, having got the switching issue under control I am not at all satisfied with the hold back property of this system. Consequently, my question is this. Seeing how the brake is definately workiing is there some reason that can make it have a reduced effect or is this "As good as it gets" with this type brake. If it is possible to be operating at a diminished capacity what can I do? # 2 My 1988 R model is a heavy spec truck. I'm for the most part very satisfied with this unit and would like to restore it to A-1 condition. The problem is that it has a double frame and rust between the members is making the tweak out of shape. What can be done short of dissassembly? Thaks in advance for any help you can give Bill
