There are several different types of noise that brakes can make. Listed are some of the most common that we encounter. When your vehicle develops a noise that your feel unsure about bring your vehicle in for an accurate diagnosis. We have certified technicians that will help you decide what services best meet your needs.
· Loud / Squeal Noise – A continuous loud squeal normally is wear indicators. It is a signal to the driver that the pads need replaced soon.
· Grinding Noise – There could be two issues when hearing this noise. One is a common noise that may be heard during the first couple stops if the vehicle has not been driven recently. The noise should disappear after a distance and does not usually indicate a problem. If the brakes pads are worn very thin and damaging a rotor, some vehicles will emit a grinding noise and/or poor braking performance. If this noise is heard, brake repair is unavoidable. Have your brakes serviced as soon as possible
· Trace Squeak / Squeal Noise – This may be the most common noise complaint. This noise usually occurs with semi – metallic brake pads while driving at medium speeds or perhaps in conditions of rain and high humidity, it’s because of the metal to metal contact. This noise does not usually indicate a problem and braking performance is not an issue. It is caused by the materials that make up the pad linings themselves. Most brake pad manufactures offer organic or ceramic pads that may make this noise less irritating but will cost a little more. Remember some noises are a very normal part of your braking system.
IS YOUR BRAKE FLUID LOW IN THE RESERVIOR
As brake pads wear, some loss of fluid is normal, however if you notice considerable loss then a leak is likely and should be inspected as soon as possible. Fluid loss will create loss of brake pressure which means no or poor braking ability. Leaks can occur at the calipers, wheel cylinders, master cylinder or any line or fitting. Our general rule of thumb is not to top off brake fluid unless a repair has been made. The first picture is a rusty brake line on the verge of leaking and the second is a rusty brake line is leaking.
WHAT DO THESE LIGHTS MEAN?
Most cars have one or two brake warning lights on the dashboard. A bulb check is performed when you first start your car and all lights will come on and go out after a few seconds. If one of the warning lights does not come on or go off, this indicates a problem.
Your brake light will stay on your dash if any of the following is occurring:
· Your emergency brake is on
· The brake fluid may be low
If your brake light comes on while driving it may indicate that you have lost brake pressure in half the brake system or that the pressure is lower on one side than the other. If this occurs you should slowing and calmly pull over and stop. If the brake system has completely failed, you will have to use your emergency brake to stop. This may indicate a leak in one part of the system, and unable to hold pressure. A towing service should be called and brought in for diagnosis and repair.
If your vehicle is equipped with anti-lock brakes and you see the ABS light staying on after the bulb check or comes on while driving this signifies a problem. The ABS controller will disable the system and your brakes will function as if you don’t have ABS. You should be able to drive safely to the repair shop for diagnosis.
