Need Brake Help

[jdataco]

To begin with this is pertaining to a 99 SR5 V6 4wd. When it is wet out or when the brakes are cool they sometimes go to the floor and i can kind of feel a vibration like somethings slipping. They also occasionally do it when i turn into a driveway with a downward slope and apply the brakes. Checked the pads, rotors, and fluid today and all looked good. Any ideas?

Can you tell if you're losing traction, as in maybe the ABS is activating? I would also check the brake lines and bleeder valves to ensure there is no leak.

Yeah it actually does feel like the ABS is activating. Kind of a fast peck peck peck peck feeling. Any idea what would causing the ABS to kick in? The truck is definately not stopping when this happens, kinda scary!
