Exhaust Brake Not Working

[DESERTJIM]

Hi Everyone,

We're back on the road again!

Noticed yesterday that the exhaust brake on our '99 Tradewinds isn't working.

I checked for a blown fuse, but didn't find one for the exhaust brake. Maybe there isn't a fuse involved?

Lots can happen when you are sitting around for a few months.......like gaining weight and the brakes quitting <smile>.

What do I do next (I mean after checking the switch)?

Thanks for any help.

Sometimes they get rusty and stick. Have you tried moving the brake by hand (when cool)? There is a special oil made to lubricate them.

Jim:

We have a PacBrake on our '98DP. I use the factory recommended lubricant (about $7 for a small bottle)since it is designed to stand up to the high temps. encountered in this area of the engine due to the exhaust manifold and turbo housing.

Freightliner told me it was most probably an in-line fuse. Gonna check that first. If it isn't the fuse, I'll go on to the unit itself.

Thanks,

Thanks. Someone else mentioned lubing. Thanks for the page which shows the unit and points of lubing.

Where is the unit located on the engine? My rig has a 300 Cat. Do I look under the bed or from under the engine?

Thanks a bunch.

I found and replaced the blown in-line fuse.

Is there any way to determine if the brake is working now while parked?
