Tim, you and I should have swapped trucks on the drive back from Cali. I'm not claiming that my brakes are awesome, but I never worry about stuff like the Big Sluice, Wipeout Hill, etc. It bugged me that they made so much noise after the water crossings on the Rubicon Trail, but they still held the truck back just fine, even with all the two-foot driving. It would be interesting to see if there is a difference or if it's just a matter of perception.
I will say that I burn through brake pads like nobody's business. It's probably partly my driving style -- I tried hypermiling and it didn't stick.
