Recall Campaign
May 2021
FL882AB
NHTSA #21V-207
Subject: FCCC School Bus Chassis Valve Stem Interference
Models Affected: Specific Model Year 2021 FCCC B2 school bus chassis (Thomas Built Buses C2 Saf-T-Liner), manufactured December 10, 2020, through February 2, 2021.
General Information
Daimler Trucks North America LLC (DTNA), on behalf of its wholly owned subsidiary, Freightliner Custom Chassis, Inc. (FCCC), has decided that a defect that relates to motor vehicle safety exists on the vehicles mentioned above.
On certain school bus chassis, the tire valve stems may contact the disc brake caliper, wearing down the stem material. Damage to the valve stem could result in tire deflation. Deflated tires can increase the risk of crash due to drivability concerns. Furthermore, a disabled bus may require the transfer of children to an alternate bus for transport in an unpredictable location, which may not be safe.
The valve stems will be replaced to ensure enough clearance with the brake caliper. Repairs will be performed by Daimler Trucks North America authorized service facilities.
NOTE: If the repair is sublet to a nearby tire service facility, the tire industry part number for the stem is 572-F19. When filing the repair claim, include only the sublet invoice, as a whole, in the Other Charges category.
There are approximately 22 vehicles involved in this campaign.
Additional Repairs
Dealers must complete all outstanding Recall and Field Service campaigns prior to the sale or delivery of a vehicle. A Dealer will be liable for any progressive damage that results from its failure to complete campaigns before sale or delivery of a vehicle.
Owners may be liable for any progressive damage that results from failure to complete campaigns within a reasonable time after receiving notification.

Make: Thomas Built Buses
Model: C2 Saf-T-Liner school buses
Production Dates: Begin: 08/17/2020 End: 03/01/2021
Descriptive Information:
Certain buses built with axial mounted brake calipers and a particular valve stem.
Number potentially involved: 22 Estimated percentage of involve with defect: 100%
Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance:
On all buses in the population, the tire valve stem extension for the inner wheel makes contact
with the disc brake caliper which wears down the stem material. Excessive damage to the valve
stem extension may result in a loss of tire pressure of the inner wheel which could lead to tire
deflation.
Describe the safety risk:
The potentially affected bus population may not be equipped with a factory tire pressure
monitoring system and only a thorough visual inspection may detect the contact between the
caliper and stem. The failure of the tire could occur at any time during the operation of
dropping off/picking up children. Deflated tires can increase the risk of a crash due to drivability
concerns. Furthermore, an inactive bus may require the transfer of children to an alternate bus
for transport in an unpredictable location which may not be safe.
Identify any warning which can precede or occur:
A thorough visual inspection may detect the contact between the caliper and stem. Operator
may hear a scraping noise from the brake caliper rubbing against the stem while driving or
braking.
If applicable, identify the manufacture of the defective or noncompliant component.: N/A

Component Name: Valve Stem
Component Description: VLV STM, 5/8 375 150 21 57

Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision.:
On February 19th, 2021, DTNA was notified by the dealer of the delivery of a bus with flat inner
tires. On February 22nd, 2021, DTNA opened an investigation for potential problem
identification. The investigation revealed that during a visual inspection of the tire, the valve
stem was contacting the disc break caliper and had been worn through enough to cause a leak.
In early March 2021 DTNA, in an abundance of caution, decided to initiate a voluntary recall on
this configuration.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufactureโs plan for
reimbursement. The valve stems will be replaced to ensure enough clearance with the brake caliper.
Repairs will be performed by Daimler Trucks North America authorized service facilities. Details of the
reimbursement plan will be included in the ownerโs notification letter.
