PDC. All kits must be in resalable condition. PAR requests must include the original purchase invoice number.
Export Distributors: Excess inventory is not returnable.
The letter notifying U.S. and Canadian vehicle owners is included for your reference.
Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code,
Chapter 301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to
you. The Act states that failure to repair a vehicle within 60 days after tender for repair shall be prima facie
evidence of an unreasonable time. However, circumstances of a particular situation may reduce the 60 day
period. Failure to repair a vehicle within a reasonable time can result in either the obligation to (a) replace the
vehicle with an identical or reasonably equivalent vehicle, without charge, or (b) refund the purchase price in
full, less a reasonable allowance for depreciation. The Act further prohibits dealers from selling a vehicle unless
all outstanding recalls are performed. Any lessor is required to send a copy of the recall notification to the
lessee within 10 days. Any subsequent stage manufacturer is required to forward this notice to its distributors
and retail outlets within five working days.

Work Instructions
Subject: Caliper Mounting Bolts
Models Affected: Specific FreightlinereBay logo 108SD, 114SD, 122SD,
Business Class M2, Cascadia, Columbia, and Coronado vehicles
manufactured January 2, 2017, through July 9, 2018, and
equipped with air disc brakes.

General Procedure
IMPORTANT: Vehicles may have both axial and radial mounted calipers. Please follow work instructions based
on the type of calipers on the vehicle.
Vehicles in groups A-C require work on the front calipers only. Lift the front axle, remove the front wheels and
work on the front calipers. Select the applicable SRT for front caliper work when submitting the claim.
1. Check the base label (Form WAR259) for a completion sticker for FL783 (Form WAR260) indicating this
work has been done. The base label is usually located on the passenger-side door, about 12 inches
(30 cm)below the door latch. If a sticker is present for FL783, no work is needed. If there is no sticker, proceed with the next step.
2. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

DANGER
When working on the vehicle, shut down the engine, set the parking brake, and chock the tires. Before
working under the vehicle, always place jack stands under the frame rails to ensure the vehicle cannot
drop. Failure to follow these steps could result in serious personal injury or death.
3. Raise the vehicle and support it on jack stands.
4. Remove all of the wheel assemblies.
NOTE: For BendixeBay logo axial caliper work instuctions, go to page 8 and BendixeBay logo radial caliper instructions,

Start on one side of the caliper and tighten all three bolts 40±20 lbf·ft (54±27 N·m), beginning with
the outer-most bolt and moving to the inner-most bolt. Then tighten the three bolts on the other side
of the caliper 40±20 lbf·ft (54±27 N·m), beginning with the inner-most bolt and moving to the outermost bolt.

property damage.
12. In a safe area, check for proper brake operation, as follows, before putting the vehicle in service.
12.1 Apply and release the brakes several times to check for air leaks and proper operation.
12.2 Perform six low-speed stops to ensure proper parts replacement and full vehicle control.
12.3 Immediately after doing the above stops, check the rotor temperatures. Any rotors that are significantly cooler than others indicate a lack of braking effort on those wheels.
13. Clean a spot on the base label (Form WAR259). Write the recall number, FL783, on a completion sticker
(Form WAR260), and attach it to the base label to indicate this recall has been completed.
