Hot Air

Will rising underhood heat cause brake air systems to fail prematurely?


MOMENT OF TRUTH

According to Petresh, Haldex has also been talking to engine and truck OEMs since 2002, discussing ways to move the brake air dryers out of the engine compartment and under the seats, or between the frame rails or behind the cab. "But as you know," he says, "most of them are still in the engine compartment."

Will that be a problem as 2007 trucks start to chalk up significant road miles? Despite their best efforts to be proactive, the component suppliers aren't resting easy on this one.

"This isn't getting a lot of press or exposure, and it could really become something serious down the road," Petresh says.
