The problem is that a faulty seal on a brake part can become damaged, which could allow brake fluid to leak. This could make the truck more difficult to stop, which increases the risk of a crash.
Drivers may notice a sudden loss of brake performance. Toyota has received reports from drivers who said the brake pedal went all the way to the floor.
The recalled vehicles were manufactured between February 20, 2018 and November 14, 2018.
According to the recall notice from Toyota:
“Due to improper manufacturing processes by a part supplier, a seal in certain brake master cylinders may become damaged over time and leak brake fluid internally, which could change brake-pedal feel could change and suddenly reduce front brake performance, increasing the risk of a crash.”
Toyota dealers will replace the brake master cylinder with a new brake master cylinder for free.
Toyota will begin notifying owners by first-class mail starting in late January 2019. For more information, owners can call the automaker at 800-331-4331, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236.
