Best Answer

Start by checking the rotors. If one or more rotors are warped you will exerience what is called "chatter". The only way to solve that problem is to have the rotors "turned" or replaced. It's usually caused by heat. Sounds like a wharped brake disc to me, you can take them off and get them checked at an engineering shop but probably lot cheaper just to stick new set on.

How do you fix the vibration at high speed and its steering wheel shake when braking just at high speed?

This can be a warped rotor or tire out of balance. If it only happens when braking it is a warped rotor.


Why would a car shake at high speeds?

wheels need balancing, sometimes shake is only evident at high speed


When training to drive a truck, do you have to do high speed braking from 100 mph or more?

Most trucking companies do not require you to do high speed braking for speeds of the extent. Normally when you are driving a truck, your speed shouldn't exceed 70 MPH due to speed limits. They will teach you high speed braking though to prepare you for a worse case scenario.


Do anti-lock braking systems work at low speeds?

It depends on the vehicle but usually they will function normally at any speed.

What causes steering wheel to shake on Honda accord 1996?

If it varies with driving speed, look for an out-of-round tire. If it vibrates only when braking, you probably have a warped brake rotor.

What is average speed and how is it different from speed?

the average speed is the speed you calculated when you have different speeds at different points or distances. It is different from speed because average speed has many speeds averaged into one speed ..while speed is specifically only one. Speed is instantaneous speed, whereas average speed is the average of the instantaneous speeds over an interval (time).


Why a car vibrate at high speed and its steering wheel shake when braking just at high speed?

High speed vibration is often an indication of a wheel that is out of balance or a bent rim. It can also be a bent driveshaft or bad U-joint. Vibration when you brake at high speed is almost always a warped rotor on the disk brakes.

What is the speed lower than the speed of sound called?

speeds lower than the speed of sound is known as the subsonic speed. speeds greater than the speed of sound is supersonic (mach 1) and speeds that are many times above the speed of sound (above mach 0) are known as hypersonic sounds.


Is variable Speed a motion?

It is not necessarily a motion in itself... Variable speed refers to something that can change speeds, or that the speeds can be changed. There are many things that can be variable speed.

Why does my steering wheel shake when I drive?

At low speed: Damaged or failed tire, bent wheel, damaged brake, damaged axle. Dangerous failure of a wheel bearing. At high speed generally a wheel balanace problem. While braking a bent or warped brake component.


What is hypersonic travel?

Answer A travel with a speed which is more then the speed of sound. Answer In aerodynamics, hypersonic speeds are speeds that are highly supersonic. The term has generally been assumed to refer to speeds of Mach 5 (5 times the speed of sound) and above.


Does a car have negative acceleration when it is entering a garage?

Many factors are in play - a major factor is in how fast do we approach this garage? Unless otherwise noted by manufacture that sensor / crash detection is in effect that would provide automatic braking, releasing the gas pedal will cause negative acceleration to a point - basically engine braking - however at low speeds the amount of engine braking is minimum to the point of idle speed at which the vehicle will roll in reverse or forward (typically - some models vary) at it's given idle speed...
