If you're feeling a shaking/shuddering through the steering wheel when braking, this could mean you have warped rotors or uneven wear in your brake pads. Check them.
It could also signify an unbalance in your tires.
If you're feeling a change in the braking, like locking up or a skidding, this could mean something is wrong with your ABS (if your model has ABS).
Check the entire front end. Wheel bearings, ball joints and tie rod ends can all wear and call this problem.
A car shaking while applying brakes is most likely caused by worn a brake pad. Check the brake system at all four wheels to find the problem.
Speed directly impacts braking distance, as braking distance increases with higher velocities. The faster a vehicle is traveling, the longer it will take to come to a complete stop once the brakes are applied. This is due to the increased momentum and kinetic energy the vehicle possesses at higher speeds, which must be counteracted by the braking system.
The belts of the tire are probably coming apart. Need to replace tire ASAP. Assuming the mechanicals have been checked. Bearing, axle, brakes, etc.
Suck my balls
you steering wheel starts shaking because you probably have warped roders your shaking will get worse at higher speeds and when pressing the brake
where is it shaking in the steering wheel or in the seat? shaking at certain speeds can be caused by a busted belt in a tire
Wheel bearing, CV joints, balljoints, "rack" steering... just about anything that's loose in the suspension.
He speeds up.
the brake rotars are out of round or warped.have them machined
It depends on the vehicle but usually they will function normally at any speed.
Steering will "wobble" at higher speeds and sometimes when braking. General looseness in steering.
