Even Toyota also same. Last time I had that deadly immobilizer problem where it cuts off fuel while driving, what did Toyota SC did? Put my car in idle for 2hours and no problem since the engine didnt suffer fuel cut. Took my car and before I reached home already engine died once. I had to went again the next day, demand to meet their manager then only they acknowledge there is an issue (it seems like they already had a case or two).

Either you demand to see a manager to discuss what you want them to do at the very least. Or alternatively you sought 3rd party workshop to bleed your brake lines like forumer is suggesting. You bark here also no helping to be honest. Take a proactive approach since it involved safety.

They replaced your brakes and rotor, that should be good. As for vibration, can't comment much. Different car, different level of shaking. Is it a 3 cylinder engine? If 3 cylinder, then what do you expect?
