The shaking when braking is warped front brake rotors, I would suspect if the brakes are applying while driving that they possibly didn't adjust the brake push rod that comes out of the booster and attaches to the pedal. Some vehicles don't have a pushrod adjustment, but they often do.I went ahead and Googled the brake booster for your vehicle and took a look at it and your vehicle actually does have an adjustment. I've attached a picture you can see the threaded rod on the brake booster with a nut you actually have to adjust that when you install a new booster and if you adjust it wrong then it actually can cause the brakes to be applied all the time and that would cause front brake rotor warpage because the brakes are dragging.If I've answered your question to your satisfaction please remember to hit accept next to my name as that is the only way that the site compensates me for my time.If you have any further questions please don't hesitate to ask, you can ask follow-up questions even after hitting accept.
