What is wrong with my brakes?
As we all know, the brakes are one of the most important parts of a vehicle and when something goes wrong with this your brakes it can be quite alarming. It's often hard to determine if the noises the brakes make are the result of something simple, for example air in the brake line, or if they are an indication of more severe damage.
It is important to remember that when your service technician recommends any repair to your brakes, it should be it should be done at the earliest possible opportunity to avoid any damage or injury. Whether you need something simple, like a brake inspection, or the problem is something more complex, we can solve it. Our factory trained technicians get your car in optimum condition, and our prices are often lower than those of an independently owned garage.
Below are some answers to common questions related to brakes that we’ve prepared to help you identify any issues you might be having with your vehicle.
Why are my brakes pulsing?
- The most likely cause of this problem is a warped rotor or out-of-round drum. This means that the brake rotor may not be perfectly flat and parallel with the plane rotation. This issue causes pronounced pulsating in the brake pedal.
- Another common cause of brake pulsating is the failure of the brake pad to retract. In older vehicles, the brake shoes are pulled back from the drum using heavy-duty springs. On the other hand, in newer vehicles the pads are pulled back from the disc by the resiliency of rubber seals. Over time, these seals age or get damaged by contaminated brake fluid and this causes them to cease working properly. This results in the pad riding against the rotor and gets worn out too soon.
- If the rotor happens to be warped, the pad can wear out without a failure of the rubber seals. This will result in the rotor wobbling while rotating and therefore it will scrape the pad as it turns. In this case the pad will wear out eventually and damage the rotor.
- If your vehicle is equipped with an anti-lock brake system (ABS), you will feel a pulsating in your brakes when having to stop abruptly. This is normal.
Why is the brake pedal sinking to the floor?
- The usual cause of this symptom is low brake fluid (possibly due to a leak) or an air leak in the brake hose. If you find a small puddle of fluid underneath your car where it has been parked, this is likely the cause.
- Another problem you might be having is the master cylinder. The master cylinders cup seals or the cylinder bore may be worn. If you have found no external leaking of fluids, this may be the problem. The master cylinder pressurizes the brake system when the pedal is depressed and provides hydraulic fluid to each of the wheels to apply the brakes. The braking system is designed to illuminate the Red Brake Warning lamp when a hydraulic failure is present.
Why are my brakes grinding?
- This sound most often indicates brake pads that have been worn down entirely. There is friction between the metal disc and caliper and this can make a very loud, metallic sound. This can “score” or scratch up your rotors, making their surface uneven. At this point your mechanic may “turn” your rotors to even the surface, or you may even need to replace them altogether. Have your brake pads replaced on a timely basis to avoid this issue.
Why are my brakes vibrating?
- A vibration in the brake pedal is most often a sign of warped rotors (but can also be an indication that your car is out of alignment). The vibration can feel similar to the feeling of a panic stop in a vehicle equipped with ABS.
- You can tell if the vibration is due to a warped rotor if the vibration occurs only during braking situations when the anti-lock brakes are not engaged. If you are doing severe braking for long periods of time, such as when driving down a steep slope or when towing, this can be the problem. Extraordinary amounts of friction are created under these conditions, heating up the rotors and causing the metal to warp. The brake pads are not able to grab the surface evenly, causing the vibration. You can avoid this unnecessary heat and vibration by stopping occasionally to let your brakes cool off if driving under these conditions.
How much does a brake job cost?
The costs of having your brakes repaired depends largely on what the source of the issue is. The garage which you choose to have your brakes repaired at will also have a significant impact on the cost. There are usually costs for the initial inspection, repairing the damaged brake system, or replacing parts. If your entire brake system needs to be replaced, this is most likely a more expensive procedure. It is a common myth that a dealerships service department is more expensive than a privately owned garage. At our service department we offer affordable and professional service performed by factory trained technicians, these technicians know your vehicle inside and out, so you can be assured your vehicle is in safe hands.
