2010 Mack chu 613 parking brake slowly engaging
in Air Systems and Brakes
Posted
New to Mack trucks ,I have a 2010 CHU 613 dump truck ..when I set the parking brakes it seems like it's taking longer for them to engage than normal and also is not evacuating the normal amount of air when you first pull the knob on the dash ...just wondering why it's all the sudden doing that ...thanks in advance
