handbrake light flashing?
 

my red handbrake light is flashing randomly while driving, i read fourms and saw that it could be low brake fluid or bad brakes, so i replaces disks and pads all around, and my brake fluid was at the full line, and the light went off and everything was normal for about 120 miles, now it back. any ideas?

they look fine, and they're sturdy all the way into the harness

Your brake fluid is low, when you go up a hill or down a hill the float triggers and turns on the light. You probably have the very very common leaking seal between the master cylinder and reservoir. wipe a finger on the master cylinder and i bet it is wet. You can order the seal kit, the seal is the same as some common audi models.
