Alternator replacement and the things to learn
The smell of brake fluid is quite distinctive! A vibrating wheel or brake pedal signals problems with a rotor surface. Your brake wear indicators could be scraping against your rotors if your brakes squeal when you release your brake pedal; however, the grinding and growling sound of metal on metal means that your brake pads have completely worn down. Regardless of the warning signs your brakes are sending you, you need to take your car in for brake repair as soon as you can. You aren't doing yourself any favors by putting it off. You will only be placing yourself and your passengers in danger by driving with bad brakes.
