Braking

[Orren Zook]

If you've got drum brakes on your coach, excessive wear on the anchor pins and/or anchorpin holes of your brake shoes can cause a harmonic vibration that makes a howling sound.

Any idea why my brakes howl when I come to a stop? If I just hit them to slow a bit they are fine but if I need to use them firmly, they will howl all the way from 60 to zero.

Most common cause is dust.
