I have a 1998 F150 4x4 4.6LV8 with 195,000 on it, Front disc brakes, Rear drum. When i go to come to a stop, 70% of the time my rear brakes will lock up and make the back end of the truck bounce and shudder, it will feel like i have no braking power to the front discs too. And when my truck dosent do that it will just feel like i barely have any braking power and sometimes my foot will go all the way to the floor board and i wont be stopping. And thr only time i have REALLY good braking power is about the first 5 min of driving it starting with a cold motor. The ABS light was on for about a month like 6 months ago and it finally just went off and now my truck does this stupid crap.. HELP!!
