Brake vibration is where a shaking motion occurs when the brakes in a car or other vehicle are deployed. This can vary from a slight shaking to a quite severe shuddering, depending on the severity of the condition. It can also be known as rotor shimmying or brake pulsation. Many Jamaican motorists notice this especially on the highway 2000 or when driving down hills.
If the brake rotors installed on the vehicle have more than .05mm of run out (where the brake rotor moves from side to side more than a minimal amount of .05mm), then brake vibration will occur through the steering. Usually, this is due to one of two different reasons. The face of the disc may have some rust or dirt on it, which is causing the run out figure to be incorrect. Such build up may occur during the lifetime of the rotor, and this can cause the run out to be up to five times the limit installed by the factory. If the problem is not due to this, it may be that a ‘thin spot’ has occurred on the rotor (where there has been intermittent pad contact instead of a constant motion). When the brake pedal is pressed this causes the brake vibration to occur. This is technically known as Disc Thickness Variation, or DTV for short.
As it is essential that your brakes run true, this must be sorted out as quickly as possible by resurfacing or skimming the rotors at Express Brakes Ja.
When the brake pedal is depressed the brake pads will now clamp the warped brake rotor which now transfers the vibration to the steering mechanisms
The first thing to do is to determine whether it is the front or rear rotors that are causing the brake vibration. If the steering wheel itself is shaking, it is more likely to be the front, whereas if the whole car and bodywork shakes, it will probably be the rear. Additionally, it is not necessarily the pair of rotors that are the problem; it may only be one of them. Finding the location of the shaking is the first step to solving the problem, however.
Depending on whether you undertake your own mechanical work, there are two routes to take here. Firstly, you can rectify the brake vibration yourself, or secondly, you can take the vehicle to a garage to resolve the issue. Either way, if the problem is a dirty brake rotor surface, a brake rotor surface that is warped due to heat, a brake rotor having the rotors turned or skimmed to present a clean, smooth surface to the brake pads can solve this. This is known as brake rotor skimming. Brake rotor skimming removes an equal amount of material from the brake rotor surface making it smooth and parallel again.
Firstly, ensure the garage you are looking at choosing is reliable – if you can get some recommendations from friends or family as well, this is always helpful. Also, make sure you have a chat with their mechanics and make sure their knowledge seems extensive enough; it is very important they know what they are doing. Are they using the latest machinery for repairing brake rotors.
On the same note, ensure if you are going to turn the rotors or fit new ones yourself, make sure you know what you are doing and don’t hesitate to call a garage if you get stuck or feel unsure. Safe braking is so important and it is imperative the work is done correctly and safely.
