Radiator service and the things to learn
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. A good brake repair technician will recommend a few preventative measures. Have your brake fluid inspected regularly for contamination by metal flakes and moisture. If you do not, your calipers and wheel cylinders will wear down much quicker.
