Although not quite accurate many professionals refer to these irregularities as warped brake rotors. Usually rotors can be machined so the rotors are flat again.

Car Shaking When Braking At High Speeds 13 Causes Solutions

Warped front disc brake rotors can cause shaking when you re braking.

Car shaking when braking downhill. The brake rotor is connected to the wheel bearing hub assembly. The steering wheel starts shaking when the brakes are applied at high speeds. This is not what anyone wants when driving highway speeds.

Applying the brakes going down hill makes the rotors get warmer than they usually do. There are a couple of things. If you feel a shuddering in the brake pedal but the steering wheel isn t shaking it s the back.

Of course there are also some other less common reasons why your car might be shaking when braking. If your steering wheel is shaking the problem is your front rotors. Ball joints tie rods wheel bearings and other parts of your suspension system wear over time.

If your shaking only happens when braking your pads or rotors are likely the cause. When this happens and the brake pads are applied again to the rotors this causes an uneven surface on the rotor to be applied to the flat surface brake pad which can cause a vibration shaking or very loud grinding sound. Heat causes metal to expand and when this happens it makes the warpage bad enough that you can feel the shaking through the car when braking.

Any of these problems can easily cause brake problems. Once the rotors cool down the warpage is less noticeable. When you hit the brakes when traveling downhill the brake rotors heat up as normal.

Car shakes when braking downhill if you re concerned because your car shakes when you re braking downhill more times than not this isn t anything to worry about. A worn wheel bearing that has too much play will cause a vibration when braking. This is also more apparent when braking on the highway at 60 70 mph.

Over time this can cause them to warp slightly causing very small low spots on the surface of the brake rotor. A shaking or pulsating when applying the brake pedal almost always indicates excessive rotor runout or a variation in rotor thickness. Most motorists have encountered this problem.

The vibration is generally caused by the brake rotors being warped. Replace the worn wheel bearing or bearings. It is pretty scary when my steering wheel shakes when braking downhill.

If your car shakes or vibrates only when turning your suspension is likely the cause. Wheel bearings allow the wheels to rotate while supporting the vehicle s weight. Bad cv bearings can cause this too though it s not as common as the rotors.
