Just changed brakes and bearings -- why are the hubs so hot?

I don't use a Prodigy, so this is an honestly ignorant question. The posts above make it sound like the boost setting applies some small voltage to the brakes even when the brake pedal is not depressed. Can this be true? Say it ain't so, Joe!

Not as far as I can tell. The Prodigy manual says, "Each incremental boost setting increases the sensitivity of the P3's inertial sensor, enhancing the participation of the trailer brakes during a braking event."

But the it says, "With the boost off, during a braking event, the power to the brakes starts out at zero and increases with deceleration. With the boost on level B1, during a braking event, the power automatically starts out at approximately 13% of the power setting and increases with deceleration. With the boost on level B2 or B3, during a braking event, the power automatically starts out at approximately 25% of the power setting and increases with deceleration."

It doesn't specifically state the difference between boosts B2 an B3, although it recommends B3 for bigger trailers.

It ain't so.

"Boost" just makes the braking a bit more aggressive in the stop. There are "off" and 3 boost positions, with higher settings recommended for heavier trailer weights relative to the tow vehicle.
