Rotors out of round - resurface or replace
It's probably shaking a lot because it needs its balancing done. Most tire stores like "Tire Works" will do your balancing for around $30.
generally a timing belt only needs replacing when it breaks
Sounds like you have a bad misfire and are running on less than all cylinders. Check that all cylinders are getting a good spark if petrol.
they dont know what the other person has done with their hands.
Sound is vibration in air, so it contains energy. It is possible to make those vibrations in energy do work, and turn them into power, in the same way as some have proposed generating electricity from waves in the ocean. Generating electricity from sound is currently impractical. Microphones can be thought of as devices which turn sound into power-- the sound vibrates a thin piece of metal, which changes the electric signal passing through the microphone. It doesn't generate electricity, but work is done when the sound pushes the metal back and forth. Another example of work being done by sound is when if high-pitched sound breaks a crystal glass.
The amount of time for a break change job depends on the vehicle's make, model, and the type of breaks that needs to be replaced. From experience two hours is the amount of time required; however many times it's discovered that the vehicle needs more then just the breaks changed once the jobs gets started, which will required additional time, parts, and money.
You've done something wrong to it.
It could have been shaken on accident many times, or the very small amount of shaking could have done it.
If it is done by one person the sound is clicking, if it is done by multiple people it is an annoying sea of clicking.
Management tels personell what needs to be done and who and how it needs Tobe done.
get wheel balancing and wheel alignment done. you might have bumped it very hard .
No, "done" does not have a short u sound. It is pronounced with a long o sound, as in "don" (d-oh-n).
