What Does it Mean When Brakes Are Glazed?
When you press on the brake pedal in your car, the brake pads come into contact with the brake rotors, which slows down the vehicle. Over time, the friction between the brake pads and rotors generates heat, which can cause the brake pads to become glazed.
Glazing occurs when the brake pads overheat and the resin that binds the pad material together melts. This creates a thin layer of glass on the surface of the brake pads. The glazed surface is smooth and hard, which reduces friction and makes it more difficult for the brake pads to grip the rotors. As a result, the brakes become less effective and the car takes longer to stop.
Causes of Glazed Brakes
There are a number of factors that can contribute to glazed brakes, including:
- Heavy braking: When you brake hard, the brake pads generate a lot of heat. This heat can cause the resin in the brake pads to melt and glaze.
- Prolonged braking: If you have to brake for a long period of time, such as when driving down a steep hill, the brake pads can overheat and glaze.
- Overloaded vehicle: If you are carrying a heavy load in your vehicle, the brakes will have to work harder to slow down the vehicle. This can lead to overheating and glazing of the brake pads.
- Worn brake pads: When the brake pads are worn down, they are less effective at dissipating heat. This can lead to overheating and glazing of the brake pads.
- Poor quality brake pads: Some brake pads are made with materials that are more likely to glaze than others.
Symptoms of Glazed Brakes
There are a few symptoms that can indicate that your brakes are glazed, including:
- Reduced braking performance: The brakes will feel less effective and the car will take longer to stop.
- Squealing or grinding noises: The glazed surface of the brake pads can create a squealing or grinding noise when you brake.
- Vibrations in the brake pedal: The glazed surface of the brake pads can cause the brake pedal to vibrate when you brake.
How to Fix Glazed Brakes
If you think your brakes are glazed, there are a few things you can do to fix the problem:
- Replace the brake pads: The most effective way to fix glazed brakes is to replace the brake pads. New brake pads will have a fresh surface that will not be glazed.
- Resurface the brake rotors: If the brake rotors are also worn or damaged, you may need to have them resurfaced. Resurfacing the rotors will remove the glazed surface and create a fresh surface for the brake pads to grip.
- Bed in the new brake pads: After you replace the brake pads, you need to bed them in. Bedding in the brake pads involves a series of stops and starts that will help to transfer material from the brake pads to the rotors. This will create a thin layer of pad material on the rotors that will help to prevent glazing.
How to Prevent Glazed Brakes
There are a few things you can do to prevent your brakes from becoming glazed, including:
- Avoid hard braking: When you have to brake, try to do so smoothly and gradually. This will help to reduce the amount of heat that is generated by the brake pads.
- Avoid prolonged braking: If you have to brake for a long period of time, such as when driving down a steep hill, try to use the engine brake to help slow down the vehicle.
- Use high-quality brake pads: Brake pads made with high-quality materials are less likely to glaze.
- Have your brakes inspected regularly: A qualified mechanic can inspect your brakes and make sure that they are in good condition.
