Jake Stopped Working
My jake brake has suddenly stopped working today. Going down steep hills/mountains I'll be in 4th gear with the Jake on High and the bus just keeps going faster and faster... it would easily head to 65 or higher. I have to ride the brake in order to keep it at 60mph. My boost gauge is only at 3 when it would usually raise when the jake is on.
Any idea how I can trouble shoot this?
In the past, I could always tell if the Jake is working by simply turning it off and I'd feel an immediate speed increase. Now there is no difference so I know it's not doing anything.
My turbo has also done a weird thing three times over the last two days. I'll be going up a hill and I'll notice my power fluctuating and the turbo not being steady.... it will go down a bit for about two seconds before coming back to normal strength. It might do this 3-4 times one after the other and then return to normal.
Other questions:
1) How long is it safe to ride the brakes while going down steep mountain passes. I'm driving South on I5 in Oregon towards California and will be heading to San Francisco (if this problem doesn't mess me up too much).
2) Is there any kind of indication of when my brakes might start to overheat? How long does it take to let them cool down?
3) Any other driving suggestions would be greatly appreciated.
