Car brakes

Probably just the brakes. You could take them apart and clean and lube the moving parts and use anti squeal on the backs of the pads.
Yes wear indicators built into the brake pads, change pads soon before you wreck the more expensive rotors they come in contact with, by soon I mean like today. Of course there's no chance of loosing brakes just money drive as you wish, I hope this helps you
