When you are experiencing a jerking or pulsing from the brakes, it is quite likely that it is being caused by a defect in the brake drum or rotor, rather than being caused by the anti-lock braking system
anti-lock braking system
ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.

. An out-of-round drum, or a warped rotor can cause unmistakable pulsating that is felt in the brake pedal.

Full Answer

Why are my brakes pulsating?

Anything disrupting the flow of brake fluid can cause braking issues. A broken or stuck brake caliper piston can’t expand or retract, leaving the brake pads in contact with the rotor. This not only can cause pulsating brakes, but can also wear out other parts sooner, like the brake rotors and brake pads.

What causes brake rotors to wear out?

These are usually caused by a worn brake pad that has no brake pad material left, but they can also be caused by a stuck brake caliper piston, stuck caliper slider, or stuck brake pads. Other defective brake parts can wear out the brake rotor.

Can Warped rotors cause vibration when braking?

The reason why warped rotors cause a vibration when the car is braking is because of the contact between the brake clamps and an uneven surface. This should cause the car to shake.

What are the signs of rotor warping in a car?

The number one sign of rotor warping is that the car will vibrate when applying brakes. This is what most car owners use to diagnose brake rotor issues.

How do I know if my rear rotors are worn?

Rotors can have grooves, as well, but it's the warping or wear that produces this particular “music” as the braking system is engaged. A bad rotor's music isn't very pleasant.
