Trying to problem solve.
So lately I've had both the anti lock light and the brake light come on for a few seconds and then they will go off. It will just happen at random times and at various speeds. Lately I've also noticed that it feels like there a vibration or slight chatter in the pedal as I'm driving or braking.
Also, when I brake, sometimes there will be more resistance in the pedal like the brake assist is working, and it feels like the truck pulls a little to the left while braking.
We did just change the front brake pads, which were shot, although I noticed this before that a couple times.
Also, there was a leak in the upper intake manifold gasket, which was causing a rough idle and lots of noise (maybe failed brake assist too?). I took some silicone gasket stuff and sealed where the leak was to see if that helped the problem (there was like a gap in the gasket that was missing). It did, the truck was much quieter and idles normal now. Still have the above mentioned issues though.
Ideas?
