Mitsubishi Fuso Truck Of America brake booster vacuum pump assembly may be affected by heat radiating off the exhaust manifold during normal engine operation.
The short version
Mitsubishi Fuso Truck of America, Inc. reported a problem with the power assist vacuum. Here is what owners need to know.
The brake booster vacuum pump assembly may be affected by heat radiating off the exhaust manifold during normal engine operation. This heat can cause the diaphragm in the pump to crack, resulting in loss of vacuum in the vacuum pump.
If loss of vacuum occurs, power brake assist may become inoperable, increasing the risk of a crash.
Take it to a dealer — they will replace the vacuum pump and install exhaust heat shields, free of charge.
