Hi,

How many of you Wanderlodge PT and WB owners have Jake Brakes on your Detroit
Diesel Silver 330 (1982-84 6V-92TA), Silver 350 (1985-89 6V-92TA), Silver 475
(1986-89 8V-92TA) or Silver 500 (1990-95 8V-92TA)?

Jake Brake is the trademark of Jacobs Vehicle Systems for compression-release
engine brakes. Its initial development was started in 1931 by Clessie Cummins
(the founder of Cummins Engine Co.), and handed down to his nephew Don Cummins,
son of Clessie's brother Deloss. The elder Cummins was looking for a way to
bring his heavy-duty diesel trucks to a stop without excessive engine wear. 30
years on, the official Jake Brake compression-release engine brake entered
production.

Jake Brakes make a machine gun sound (roughly: RAT-A-TAT-TAT-TAT) as you apply
them. Its loudness depends on the exhaust system type and how well it is
maintained. It was this aspect that caused many cities to ban the use of Jake
Brakes in certain parts of the town. But not all Jake Brakes sound like this,
though. The RAT-A-TAT-TAT-TAT sound would refer to the compression-release
Jakes, not the exhaust ones.
