ABS/Brake problem

[9ine]

1997 Limited

So the other day i was stranded cause my starter contacts were toast... i was under the hood with someone else trying to get the truck started (finally did to be able to drive it to the shop) but the one guy was unplugging wires. I noticed he unplugged the one connector from the box that the brake lines go to in the back left corner under the hood... i connected it back but now once I'm slowing down and near stopping, the brake peddle chatters and there seems to be a noise coming from under the hood... a sort of buzzing. Its no longer a smooth brake-to-stop, it just makes the noise and chatters when about to come to a stop, then goes away when it comes to a stop.

Any idea what this is? Thanks!

i have this same issue. it started for me when i put some 265/75/r16 km2's on some heavy steel tacoma stocks. now i have some 16x10 alloy wheels which are lighter than the taco stocks but i have 315/75/r16 km2's which are quite a bit heavier than the 31's. the problem with the brakes buzzing is much more frequent now. i hope this thread gets some attention.

when i had my starter contacts replaced the mechanic said that it might be a wheel speed or abs sensor? any thoughts?
