The brake burnish procedure is called 10/30/30 and 5.
Under safe conditions, make 10 stops from 30 mph with a 30 second interval of time between each stop to allow the
brakes to cool slightly. The time it should take to stop from 30 mph to 0 mph is 5 seconds. This will equate to a gentle
stop. Repeat this process up to three times if necessary, allowing sufficient time to cool between sessions.
During the burnishing procedure for new pads or shoes, it is common to smell the resins coming out of the lining
material. This odor may disappear near the end of the burnish or shortly after the truck goes into service.
The brakes may also appear to be smoking. Again, these are the resins and other organic materials getting baked
out of the linings. If you suspect one of the brakes is not performing the way it should, measure the brake rotor or
drum temperature using an infrared hand held thermometer.
The infrared thermometer readings can vary depending on the location of the infrared beam on the object. Try to get
within 12 inches of the drum or rotor and always try to check the same area of the component. Brake temperatures
can vary from side to side on an axle as well as axle to axle. Try not to exceed 700° F (371.1° C). After the burnishing
is complete, allow the brakes to cool completely to ambient temperature. All wheel-end brake actuation should be
checked prior to putting the vehicle back in service.
Following this procedure should provide sufficient burnishing of the brakes and allow the truck brakes to perform as
intended. Contact Pierce Customer Service if you have any questions or concerns regarding the brake system or
performance.
