Question One:

Do any of the rotors have

bright orange or red

color edges?

Check the box(es) on the

vehicle diagram to the

right for any found.

Normal Evidence of thermal overload

Question Two:

Are any of the calipers

coated with a bright

orange or red colored

dust? Check the box(es)

on the vehicle diagram to

the right for any found.

Normal Evidence of thermal overload

Question Three:

Are any tappets and/or

guide pin boots heat

damaged? Check the

box(es) on the vehicle

diagram to the right

for any found.

Typical Evidence of thermal

overload

Evidence of thermal

overload

Are

both boxes

on a single axle

checked?

Are

any boxes

checked?

Only

one box has a

check mark?

YES

Go to Section Two (over)

In cases where more than one wheel end is affected — but on different

axles — complete a separate checklist for each brake being examined.

This is not a single wheel end

Thermal Overload event.

When both ends of an axle are

affected, a thorough brake system

diagnosis is needed, as other

factors — such as brake balance,

overloaded vehicles, or extreme

use — are more likely the source.

SECTION ONE: Inspect the Vehicle

All foundation brakes are designed to convert kinetic energy (energy of motion) into heat

and work (to stop the vehicle).

Air disc brakes work the same way and in everyday operation — compared to drum brakes

— will produce higher braking temperatures and cool off faster. Also, air disc brakes

will often have differences in temperatures at wheel ends on the same axle. The actual

temperatures reached will depend on the vehicle conguration, vocation and brake usage.

This document is intended to help technicians identify instances where an individual wheel

end has evidence of thermal overload, and check for potential causes.

STOP!
