Warning Signs Your Brakes Need To Be Checked
When it comes to your car’s safety, brakes top the list of systems that need monitoring. However, many people are unaware of the signs that indicate a car’s brakes may need maintenance or repair. For routine maintenance, it’s important to check the vehicle’s braking system at least once a year. A thorough inspection should include brake lining wear, brake fluid level, rotor thickness, condition of hoses and brake lines, brake and dash warning lights, as well as taking the car for a test drive to detect other potential brake system problems. It is important to be alert and recognize the danger signs of brake problems. Other warning signs include an illuminated brake warning light, brake grabbing, low pedal feel, vibration, hard pedal feel and squealing.
