Filing in context
The Pressure control and transmission unit is the most frequently cited component category in this archive, appearing in 11 of its 4,890 filings. This filing is one of 6 Mitsubishi notifications from 1997 in this archive. For scale, 1,069 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 3 months.
Defect
The check valve located inside the vacuum hose of the brake booster was manufactured with a machining defect. Continued use prevents the internal components of the valve from functioning. In the worst case, the brake booster ceases to operate, and normal pedal effort becomes insufficient to achieve adequate braking.
Corrective action
On all vehicles, replace the vacuum hose containing the affected valve with a conforming assembly.
