Air brake push rod inspection on motorhome

Look up air brake adjustments on the internet. The air brake push rod length seen when the brake is applied is an indication of when the brakes need an adjustment. Even with automatic adjusters the brakes may need to be manually adjusted. The job is not difficult and can vary depending on what type adjusters are installed. I check and adjust my brakes at each major maintenance cycle and find the manual adjustment gives a more uniform push rod length than depending on the automatic adjusters. This does not mean that the automatic adjusters are not working properly, just that they may not be as precise as a manual adjustment.
