If you mean when you are coming to a stop, and press on the brakes, you feel a vibration- this most likely means that your brake rotors are warped and need to be turned. If you mean you are already at a full stop, in idle, and you press the brake and feel a vibration- it may mean a vacuum problem in the engine or something like that. So it depends- is it your brakes vibrating, you feel it in the pedal? Or is it your engine suddenly running rough and the whole front end of the car shakes?
Have the tires Balanced. Then check alignment. If still shakes is it when your press the brakes? If so check the rotors and abs system. Or if it could also be the over drive if it is when shifting gears. Try running it with the over drive off.
loose rear caliper or drum brakes, could be loose hardware or on disc brakes, possible warped rotor
If the car shakes when you press on the brakes, you probably have warpped brake rotors, and the squeak is probably some worn out front brake pads. I would have your rotors checked and either replaced (which Mercedes highly recommends or re-surfaced)
if it is hard to press on the brakes it usually indicates that you have a malfunctioning brake booster. Since brake boosters are vacuum assisted, it could also be that you have a disconnected vacuum hose or a leaking hose.
The car "jerks". Pulls to one side or vibrates? Vibration when applying brakes is most likely warped rotors. Another cause could be loose caliper bolts. If the car is pulling it may be a caliper sticking or worn suspenion/steering parts.
Go get your breaks checked out. You may need new breaks.
Your universal joints are shot, get them replaced asap!
press the brakes and then press the start/stop button
you should gently press the brake pedal and gently press the gas pedal, the increase friction will dry the brakes.....
If a calliper is "hanging", it could be causing the brake pads to press against the rotor and overheat the brakes. You may want to see if the calliper is dragging.
hammer,vibration and press of piles
i ment that if the sensor in the dash stays on after i press the brakes and dosent go off till i turn the car back on and dont press the brakes?
