PART 12: ADDITIONAL TESTING PROCEDURES

There are many safety and operational functions to test on a trailer, but there are a

few which are widely regarded as VERY important. With the MUTT

be performed without the truck or tractor, quickly, accurately, and in most cases, with

only one person. Below are a few common system checks that can be performed

using the MUTT

• One-man leak and shake testing throughout the trailer.

• Push rod travel measurements.

• Slacker adjustment reading speciﬁ c to manufacturer’s speciﬁ cations on

brake chamber and proper operation notes.

• Even brake pressure activation.

• One-man, wheel, off-ground testing for brake strength and operation.
