Toyota Repair: adjusating parking brakes on a 2003 Sienna, parking brakes, ratchet wheel

Question
How do you adjust the parking breaks on a 2003 Sienna?  Does it have to be done manually or does it adjust while going in reverse?  While depressing the Parking brake?  Or in some other fashion?

Answer
The auto adjusters don't work very well, the parking brake is adjusted by adjusting the rear brakes, the wheels should be removed, there is a small hole in the drum that can be used to turn the adjustment wheel for the brakes, it can only be turned one way, it has a ratchet wheel so be sure not to adjust it too tight, there should only be a very slight drag when rotating the drum.
