why does my truck vibrate when i brake

Brake Vibration: Common Questions Answered What is Brake Vibration? 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. What causes it? 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 вthin spotв 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. How to rectify the problem 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 disc surface, having the rotors turned or skimmed to present a clean, smooth surface to the brake pads can solve this.


If the rotors have a thin spot, they will need to be replaced with new ones. Regardless of which method you choose, they must be checked when fitted back to the car that the run out is the correct measurement. What to look for when choosing a garage to do the work Firstly, ensure the garage you are looking at choosing is reliable в 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. Competitive pricing is also going to be an issue, but cheapness does not always mean quality, so sometimes it may be better to choose a slightly more expensive option for better service. 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 donвt 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.
A number of things can cause brake pedal vibration, a potentially serious problem that can make it unsafe to drive your vehicle. In this article, we ll look at some of the more common reasons this issue occurs. However, no matter what s responsible for the pedal vibrating, the solution is the same. Bring your car or truck into Brake Works right away for service. 1. Brake pad issues If your pads are contaminated with oil, dirt, or other substances, then they can cause vibration when they grip the rotor. This can also happen if the pads are warped, damaged, or excessively worn. 2. Brake disc issues As discs go bad, they can make your brakes grab unevenly or, without warning, making the pedal shake. A number of things can cause the discs to develop problems, including wear over time due to contact with the pads. It s important to always replace both discs, even if only one of them is causing the problem. 3.


Alignment issues If your vehicle is out of alignment, then you re likely to notice pedal vibration when you step on the brakes. Misalignment can also cause many other problems, such as rapid tire wear and damage to suspension components. One way to test for alignment problems is to bring your car up to 50-60 mph on a straightaway when there s no other traffic nearby. Let go of the steering wheel for a brief moment and notice if the car immediately tries to go to the right or left. If it does, then it likely needs to be realigned. Get it to Brake Works immediately. 4. Worn suspension components Ball joints, tie rods, wheel bearings, and other parts of your suspension system wear over time. Any of these problems can easily cause brake problems. If you re experiencing brake pedal vibration, then don t take chances with an unsafe vehicle. Get your car or truck into Brake Works right away, and let our technicians correct the problem. Your safety is too important to take chances with.
