Hi,
Pull that fuse! ABS brakes are useless as far as I am concerned. It sounds like you need new brakes and or roters. I would get a mechanic to check that out if the car continues to shake when you slow down. When your roters are warped, the car tends to shimmy because a smooth brake pad is pressing against a warped roter. But pull the fuse and see how it goes.
Hope it all workes out for you.
