It's either the brake pads or rotors. If you are a hard braker stopping at the last minute, or have frequent stops from highway speeds, your rotors can heat up to very high temps. When you park your car with smokin hot rotors they can warp as they cool because the spot where the pads sit will cool at a different rate than the rest of the rotor. This can be even worse if you drive through a puddle before you park the car. Have your pads changed, and your rotors either replaced or fixed.
Warped rotors
If the steering wheel shakes, but to car doesn't, when applying brakes - your front rotors are warped (if you have disc brakes)...if you have drum brakes, the drum could be cracked or the pads worn unevenly If the whole car shakes, and the steering wheel only seems to react to that, when applying brakes - see above statement, but apply to the rear end. If the whole car shakes, including the steering wheel - all four corners are bad, and you're an accident looking for a place to happen soon. In any case, go to your nearest service center ASAP.
if you car shakes when its fully stopped it may be the harmonic balancer, take it to a garage. is it shakes only when you are braking while stopping than have you brakes checked
You went thru a deep puddle with hot brakes. The disc gets doused in cold water and warps.
i had that happen to did you change your own brakes? because i sent mine in and it cost like $300 to get it fixed plus get brakes put on so idk what they put on to fix that ticking noise.
worn front end parts (steering or suspension) could cause a car to shake when appling the brakes.
Warped brake rotors/drums.
because you did not step on your clutch pedal
You increase the frictional force by applying the brakes.
simple hydrolics. You have a canistor (master cylinder) which holds the fluid. When you push on the pedal, The cylinder opens and pushes fluid to the brakes which push against a disc to slow the momentum
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)
u push ur foot and the oil pushes the piston behind the pad
