Filing in context
The Pressure Control and Transmission is the most frequently cited component category in this archive, appearing in 7 of its 4,890 filings. This filing is one of 6 Toyota notifications from 1996 in this archive. For scale, 311 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 4 years and 6 months.
Defect
On diesel engine-equipped vehicles, the blade retention grooves in the vacuum pump rotor that supplies negative pressure to the brake booster were improperly machined. Continued use causes the carbon blades to wear and, in the worst case, fracture, preventing the pump from generating negative pressure. As a result, brake effectiveness is reduced under normal pedal effort.
Corrective action
On all vehicles, replace the vacuum pump rotor with a conforming part and replace the blades with new ones.
