Axial Mounted Brakes
p4 mm 42.05.002
- Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
- Raise the vehicle and support it on jack stands.
- Remove all of the wheel assemblies. For instructions, see General Information, Wheels and Tires in the New Cascadia Workshop Manual.
- Set a torque wrench to 350 lbf·ft (475 N·m) and tighten the caliper mounting bolts
following the tightening pattern shown in Fig. . If they do not turn, no further work is needed. If they turn, take the vehicle to
an authorized Freightliner dealer to have all of the caliper bolts on that wheel end
replaced. Due to limited caliper bolt access, it may be necessary to use tool DDC
DSNCHA018005 referenced in tool letter 18TL18. If the tool is needed, use tool DDC
DSNCHA018005 only and no other tools. See Fig. . If the tool is needed, see Table for torque specifications for a 47 in (119 cm) long wrench.

- Remove the jack stands and lower the vehicle.
Important: The following information applies to all types of axial mounted brake applications.
Note: In all steps that require a torque wrench, use a Snap On torque wrench ATECH4RS600, or an equivalent, with a center to handle length of 47 inches (119 cm).
