During your car’s lifetime you are more than likely going to have to change the Front Brake Discs and brake pads due to wear, but are more likely to have to replace rear brake discs and pads due to corrosion. Using your car less frequently and leaving in the garage is when rust will set in.
Braking systems rely on friction to bring the vehicle to a halt – hydraulic pressure pushes brake pads against a cast iron brake disc or brake shoes against the inside of a cast iron drum.
When your car slows down the load is transferred to the front wheels meaning that the front brake discs and pads do more of the work in stopping the vehicle.
So how do you know if your brake discs have worn out?
Using your eyes
You can normally see the brake pads through your wheels. Turning the steering wheel until the wheels point to the very far left or right will expose the insides of the wheels for viewing the brakes easier. You should be able see how much thickness there is left on the pad. At least one Â¼ inch of brake pad needs to be visible. If there appears to be less, get them replaced.
When the brakes on your car are exerted while driving, the pads exert pressure against the brake discs which brings the car to a standstill. Over time, your brake discs will also wear down and you may find the brake pads have created a slight groove in the disc. This is very harmful to the disc and this must be avoided. Healthy brake discs will be a smooth and uninterrupted surface, free of dust, grooves and grit.
Using your ears
Listen for brake noise. When you drive, the car will tell you if the brakes or brake discs are in need of replacing. Squealing or squeaking is usually an excellent indication. If you hear grinding, head straight to the garage, because this is a definite sign that you have brake wear on your pads and they are worn to the metal. This puts you in danger of ruining your brake discs.
If, when you press your brake pedal, you find that you feel a vibration or wobble, it is very possible that the brake discs have become warped. That will be more likely to be the case if you have been hearing a grinding sound a while and have ignored it. Brakes get tremendously hot when hit and the metal will easily warp. If you feel the car moving to one side when braking, it will be a warning that the brake pads are failing to make a good contact with the brake discs.
