Air Barkes
« on: September 20, 2016, 07:32:40 PM »
We have a question about the brakes on our 2001 Monaco Dynasty. We have been told that it is common for moisture to cause corrosion on the brakes thus causing them to lock up.  This appears to have happened twice on our coach. If this is in fact what is happening, how do we prevent it and what is the best practice to get the brakes to free up?

I can think of two places that moisture can adversely affect air brakes:

1.  If the air dryer fails and moisture gets into the air suspension and air brake system, it can certainly cause corrosion and major problems.  Yes, routine servicing of the air dryer is part of DP maintenance.

2. Moisture on the shoes/pads can cause them to stick to the drum/disk.  This often happens when parked for long periods of time. Sometimes it takes a bit of work to break the shoes/pads loose.  And at that point, it is reasonable that the shoes/pads are glazed.  A couple of hard applications of the service brakes should clear that up. Yes, with an exhaust brake or engine compression brake, it is easy to UNDER use the service brakes.
