Official summary
This Preliminary Information communication provides information to the technician about vehicles with a spongy brake pedal after a hydraulic brake component was disconnected or replaced. The brake lines between the master cylinder and the antilock brake system module are routed higher than the master cylinder. If air enters the system it will travel to this high point if the system is opened for a repair. The technician will need to perform an automated bleed procedure using the scan tool to ensure all the air is purged out of the hydraulic system.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
