The issue
Certain trucks were built with a foot controlled brake valve that may, if a combination of conditions occur, malfunction by allowing air pressure to bypass the control piston "O" ring. If present, these conditions may, without warning, cause overly aggressive braking during normal brake applications resulting in the potential for a vehicle crash. Correction: Actuator plunger under brake pedal will be replaced as well as the floor mounted brake valve mounting plate and pedal mounting bracket under valve.
Description (français)
Sur certains camions, l'air comprimé peut contourner le piston de commande de la soupape de freinage de la pédale de frein et accroître excessivement la puissance de freinage, ce qui risque de provoquer un accident.
