I'd throwing diagnosing sticking brakes on there.
figuring out what was wrong with my brakes on my '05 gs took a while (and you're help!).
It ended up being a leaking master cylinder, but along the way I found a few other things to check, namely the pin that can get gunked up and causing sticking....
Edit: forgot to add, the busted micro-switch that can be a problem for the servo assisted ABS's. Also having gunk stuck inbetween the pistons and the caliper that can cause stickyness..
I'll think some more about things I've come across in the forum... Fortunately (or unfortunately) the leaky master cylinder was the only problem I had in the year or so I owned my '05 GS...
