Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance: A single caliper-mounting bolt may be under torqued. On
certain vehicles, one of the six brake caliper mounting bolts on the driver side steer axle may be
incorrectly torqued. This could result in surrounding caliper bolts to loosen.
Describe the safety risk: Insufficiently torqued bolts may not provide adequate clamping force
between the brake caliper and brake anchor plate potentially resulting in reduced brake effectiveness.
Reduced brake effectiveness could lead to a vehicle crash.
Identify any warning which can precede or occur: N/A
If applicable, identify the manufacture of the defective or noncompliant component.: N/A

Name: Caliper Mounting Bolt Description: Caliper Mounting Bolt Part Number: N/A
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision.: August – September 2020, DTNA truck manufacturing plant during a quality
audit, a single loose caliper mounting bolt was identified. DTNA notified the axle assembly supplier and
began a plant inspection. The inspection identified 8 of 148 vehicles with a under torqued mounting bolt
in the same fastener location. During this analysis, the axle assembly supplier had identified a single
operator not following the standard torqueing procedures for one caliper mounting bolt on one
configuration of axle, but it was unknown if this created a safety risk. October – December 2020, a
performance study to understand the impact of that single loose bolt was performed by the caliper
suppliers. The study indicated that if that bolt were loose, there would be a gradual loosening of the
adjacent bolts over time. In reviewing this study, it was found that this was a worst-case scenario and
may not be representative of typical customer use. January 14, 2021, out of abundance of caution and
with no field reports or warranty of loose caliper bolts, DTNA decided to initiate a voluntary safety recall
for vehicles identified by the axle assembly supplier equipped with air disc brakes and a certain steering
arm configuration manufactured within the above reported dates.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for
reimbursement. Potentially affected vehicles will be inspected and repaired as necessary. Repairs will

Lorsque vous remplacez les plaquettes de frein, les sabots, les rotors ou les tambours, remplacez toujours les composants comme un jeu d’essieux.
Toujours reliner les deux jeux de freins sur un essieu en même temps.
Remplacez toujours les deux rotors/tambours sur un essieu en même temps.
Installez toujours le même type de garnitures, plaquettes ou tambours/rotors sur les deux extrémités d’essieu d’un seul essieu, et les quatre extrémités d’ essieu d’un essieu tandem, au en même temps. Ne mélangez pas les types de composants.
Le fait de ne pas le faire pourrait causer un freinage inégal et une perte de contrôle du véhicule, entraînant des dommages matériels, des blessures corporelles ou la mort.
6. Retirez la goupille de retenue, la goupille fendue et la retenue de plaquette de frein. Inspectez le matériel de plaquette de frein pour s’assurer qu’il est en bon état. Si c’est le cas, réutilisez le matériel de plaquette de frein. Si le matériel de plaquettes de frein n’est pas en bon état, remplacez les ensembles de plaquettes de frein aux deux extrémités de l’ essieu.
7. Retirez les plaquettes de frein.
8. Retirez les boulons d’étrier.
IMPORTANT: Les assemblages étrier/support sont gauchers et droitiers. S’assurer que le montage correct (gauche ou droite) est installé de chaque côté du véhicule.
9. Alignez l’étrier/support sur le rotor en poussant l’étrier contre l’étagère de la plaque de couple, puis installez l’ étrier/support à l’ aide d’un nouveau support d’ étrier boulons. Voir Fig. 2.
10. Serrez les boulons de montage du support en deux étapes comme suit.
10.1 Commencez d’un côté de l’étrier et serrez les trois boulons 40±20 lbf·ft (54±27 N·m), en commençant par le boulon le plus intérieur et en passant au boulon le plus extérieur. Ensuite, serrez les trois boulons de l’autre côté de l’étrier 40±20 lbf·ft (54±27 N·m), en commençant par le boulon le plus intérieur et en se déplaçant vers le boulon le plus externe. Voir Fig. 3.
10.2 Répétez ce processus en augmentant la valeur de couple à 375±25 lbf·ft (508±34 N·m). Si l’outil

AVIS
Ne pas utiliser un outil moteur pour serrer l’écrou manuel de réglage de frein, ou utiliser une force
excessive pour serrer l’écrou. Cela pourrait endommager l’écrou de réglage de frein manuel. 13. Installez les plaquettes de frein. À condition qu’il soit en bon état, utilisez le matériel de plaquette de frein
enlevé plus tôt.
14. Arrêtez l’écrou de réglage trois clics.
15. En utilisant les deux goujons marqués plus tôt comme guide, installez l’ensemble de roue. Lorsqu’il est
correctement installé, une ligne tirée de la tige de soupape à travers le centre de l’ensemble de roue doit
aller entre les deux goujons marqués.
16. À l’aide d’une jauge de sortie de pneu, mesurez et enregistrez le ruout radial du pneu et de la roue. Marquez le point le plus élevé sur le pneu et la roue. Faites pivoter le pneu et la roue jusqu’à ce que la tache haute soit à la position 12 heures (sans permettre à l’assemblage de tourner). Desserrez tous les écrous de patte pour
laisser l’assemblage se déposer, puis serrez les écrous de patte dans la séquence appropriée. Voir le
groupe 40 du manuel d’entretien du véhicule applicable pour la séquence de serrage. Le ruissellement radial devrait être très proche de ce qui a été enregistré à l’étape 3. Sinon, répétez cette étape. Consigner le
roulage radial « final », noter l’emplacement de la roue et inclure l’information dans la demande de
rappel dans OWL.
17. Soulevez l’ essieu avant, retirez les supports de vérin, puis abaissez l’ essieu avant.
18. Chargez le système d’air et vérifiez les fuites.
Ne pas faire fonctionner le véhicule tant que les freins n’ont pas été réglés et vérifiés pour le bon fonctionnement. Cela pourrait entraîner une capacité de freinage inadéquate ou inexistante, ce qui
pourrait causer des blessures corporelles ou la mort, et des dommages matériels.
19. Dans un endroit sûr, vérifiez le bon fonctionnement des freins, comme suit, avant de mettre le véhicule en
service.
19.1 Appliquer et relâcher les freins plusieurs fois pour vérifier les fuites d’air et le bon fonctionnement.
19.2 Effectuez six arrêts à basse vitesse pour assurer le remplacement approprié des pièces et le contrôle
complet du véhicule.
19.3 Immédiatement après avoir fait les arrêts ci-dessus, vérifiez les températures du rotor. Tous les rotors qui sont significativement plus frais que d’autres indiquent un manque d’effort de freinage sur ces roues.
20. Nettoyer une tache sur l’étiquette de base (formulaire WAR259), inscrire le numéro de rappel, FL873, sur une
vignette rouge (formulaire WAR260) et l’ attacher à l’ étiquette de base, en indiquant ce travail est terminé.

Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance: A single caliper-mounting bolt may be under torqued. On
certain vehicles, one of the six brake caliper mounting bolts on the driver side steer axle may be
incorrectly torqued. This could result in surrounding caliper bolts to loosen.
Describe the safety risk: Insufficiently torqued bolts may not provide adequate clamping force
between the brake caliper and brake anchor plate potentially resulting in reduced brake effectiveness.
Reduced brake effectiveness could lead to a vehicle crash.
Identify any warning which can precede or occur: N/A
If applicable, identify the manufacture of the defective or noncompliant component.: N/A
Involved Components
Name: Caliper Mounting Bolt Description: Caliper Mounting Bolt Part Number: N/A
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision.: August – September 2020, DTNA truck manufacturing plant during a quality
audit, a single loose caliper mounting bolt was identified. DTNA notified the axle assembly supplier and
began a plant inspection. The inspection identified 8 of 148 vehicles with a under torqued mounting bolt
in the same fastener location. During this analysis, the axle assembly supplier had identified a single
operator not following the standard torqueing procedures for one caliper mounting bolt on one
configuration of axle, but it was unknown if this created a safety risk. October – December 2020, a
performance study to understand the impact of that single loose bolt was performed by the caliper
suppliers. The study indicated that if that bolt were loose, there would be a gradual loosening of the
adjacent bolts over time. In reviewing this study, it was found that this was a worst-case scenario and
may not be representative of typical customer use. January 14, 2021, out of abundance of caution and
with no field reports or warranty of loose caliper bolts, DTNA decided to initiate a voluntary safety recall
for vehicles identified by the axle assembly supplier equipped with air disc brakes and a certain steering
arm configuration manufactured within the above reported dates.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for
reimbursement. Potentially affected vehicles will be inspected and repaired as necessary. Repairs will
be performed by Daimler Trucks North America authorized service facilities. Customer notification will be
done by first class mail using Daimler Trucks North America records to determine the customers affected.

WARNING
When replacing brake pads, shoes, rotors, or drums, always replace components as an axle set.
• Always reline both sets of brakes on an axle at the same time.
• Always replace both rotors/drums on an axle at the same time.
• Always install the same type of linings/pads or drums/rotors on both axle ends of a single axle,
and all four axle ends of a tandem axle, at the same time. Do not mix component types.
Failure to do so could cause uneven braking and loss of vehicle control, resulting in property damage,
personal injury, or death.
6. Remove the retainer pin, cotter pin, and brake pad retainer. Inspect the brake pad hardware to ensure it is
in good condition. If it is, reuse the brake pad hardware. If the brake pad hardware is not in good condition,
replace brake pad sets on both ends of the axle.
7. Remove the brake pads.
8. Remove caliper bolts.
IMPORTANT: The caliper/carrier assemblies are left and right handed. Ensure that the correct assembly (left or
right) is installed on each side of the vehicle.
9. Align the caliper/carrier assembly with the rotor by pushing the caliper against the shelf on the torque plate,
then install the caliper/carrier assembly using new caliper mounting bolts. See Fig. 2.
10. Tighten the carrier mounting bolts in two steps as follows.
10.1 Start on one side of the caliper and tighten all three bolts 40±20 lbf·ft (54±27 N·m), beginning with
the inner-most bolt and moving to the outer-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. See Fig. 3.
10.2 Repeat this process, increasing the torque value to 375±25 lbf·ft (508±34 N·m). If tool
