Hi,

My truck shakes when I brake from high speeds. Specifically, 45-55 MPH but less violent shakes at other speeds. It doesn't happen while accelerating, so I ruled imbalanced/misaligned tires out. My rears are squeaking at me I believe it is just the brake pads needing replaced (correct me if I am wrong about that please) but also my brake pedal pulses when I push the brakes. Not all the time, but especially coming to a stop at slow speeds. Warped rotors?

Yep, you are probably correct though tie rod ends can cause this as well.

Here is a guide to help you see what's going on:

So, I drove it around today without changing anything out yet and the noise stopped. I can't hear it anymore. Is it possible that the speaking was just thin rust buildup scraping away? It has been raining over here quite often recently. As for the shaking, I will check out the rotors and tie rods.

Yes, this is very possible. The rust could be getting cleaned off of the brake rotors which is common. Use 2CarPros anytime, we are here to help. Please tell a friend.
