Okay well today my truck started acting weird. While I was out driving on the freeway, a few random times the truck started pulling towards the right and vibrating and making a sound similar to that of when you are driving on the freeway and drift too far to the side and hit the "wake up" things that are chopped into the ground. It did it a few times when I tried to get on the gas real hard in the city too. The vibration was similar to that also. It would do it randomly and then stop all of a sudden and be fine. Stopped by Autozone and got my codes scanned and I still have the same ones, 2 misfires and a low egr flow. Those might even be fixed, I reset them so we'll see if they come back tomorrow. I checked trans fluid and it was good, actually over the max line (gonna be taking it in for a flush soon so that will get leveled out). Both my ABS light and regular brake light are on. The regular brake one comes and goes. Haven't got the ABS one checked yet, I'm gonna try to tomorrow. The fluid is full in the brake reservoir and the ebrake is as released as it's going to get, so what else could be causing the brake light to come one? Thanks in advance guys.. :eek:

A bad or loose hub assembly (bearing) could trigger a false ABS activation and/or cause the light to come on.

Okay I'll check those tomorrow. The one I'm really wondering about is the regular brake one, the light that comes on when you engage the e-brake, it's staying on and the e-brake isn't engaged and the fluid is maxed out, I don't know what other things can trigger that one. I can get the ABS one scanned at the dealership I'm pretty sure but I don't think they can scan the regular brake light.

It could be a bad fluid level sensor in the brake master cylinder reservoir or it's just on because the ABS light is on...

If its not that can a broken drive axle also cause that making the ABS sensor to trip? Something to look into.
