Hey guys! So I drive a 2013 Twofortwo and I recently changed the brake pads and brake drums. The mechanics also rotated the rotors twice! I keep spending money on mechanics and there is still a very loud squeal whenever I brake that comes and goes. It stresses me out because I get so embarrassed.. Anyone else experience this? I've done all I can ? I'm pregnant so I only need this car until next year then I can get a new one. Any advice??
