Rotor surface issues cause brake pedals or wheels to vibrate and also require immediate brake repair. Brakes that squeal when the brake pedal is released are letting the driver know that the brake wear indicators and rotors are scraping together. A grinding or growling sound means that the brake pads have worn away entirely. Experts recommend a few preventative measures. Have your brake fluid inspected regularly for contamination by metal flakes and moisture.
