Neat twists and turns mark this episode as one of the better series offerings. The one glaring flight of Hollywood make-believe was immediately apparent to this mechanic, though. (As its departure from fact has no bearing on the storyline, I don't consider it a spoiler - just an amusing goof!) When Mason and Drake are interviewing the truck driver whose vehicle crashed into a parked car early in the episode, the driver claims his air brakes failed because of a hose that appeared to have been cut with a knife blade. He also stated he was able to drive the vehicle despite the broken hose, by using the hand brake.
As any auto mechanic can tell you, - unlike hydraulic brakes which are off unless the brake pedal is applied - air brakes work on the dead-man principle for safety of the general public. An air compressor powered by the engine has to build up enough air pressure to RELEASE the brakes before a vehicle equipped as such can move. (This explains that loud HISSSSS one hears when a tractor-trailer rig is ready to move out.) Pressing the brake pedal opens a dump valve, lowering air pressure and letting the brakes engage.
A cut brake hose in such a system would never allow the pressure to reach the brake-release point, rendering the vehicle virtually impossible to drive without extensive brake damage and strain on the engine and transmission, too. I kept waiting for Drake to catch the driver in this tall tale, but not to be.
Once the story begins to come together, it moves quickly. Don't go to the fridge for that cold drink, until the show's over!
