Exhaust Brake Maintenance

PACBRAKE's MAINTENANCE LUBE

Pacbrake exhaust brakes are relatively maintenance free when used at every opportunity. However, to get the maximum amount of trouble free service a few areas require periodic lubrication.

Lubrication is one key factor for trouble free service of your exhaust brake. The two reasons that give an exhaust brake problems are worn parts and seizing parts. Worn parts are caused by extreme use without the benefit of the proper lubrication. Seized parts can be attributed to seasonal use and lack of lubrication. Periodic lubrication will prevent these two issues. Applying Pacbrake’s synthetic lubricant to the moving parts at every oil change will eliminate both these problems.

FOR OPTIMUM RESULTS, FOLLOW THESE SIMPLE STEPS

With the engine off, apply a sufficient amount (4-5 drops) to the following locations:
- both cylinder pivot ends [A & D]
- cylinder air line port [B] (some fitting removal required)
- the main butterfly shaft [E] (this is an area of critical concern,
we recommend a pretty good dose of lube here)
- cylinder rod [C] (cylinder rod must be extended when applying)

PRXB only:
- the base of the spring lever [F]

Once all points have been lubricated, cycle the exhaust brake either electronically or manually a few times to work the lubricant in.
