Pulsating Brake Pedal?

Pulsation or vibration is noticed when brake pedal is pressed.A shuddering or jerky stop during normal braking.
Customers will feel a vibration or pulsation in the brake pedal when the brakes are applied if a brake rotor is warped.This usually means a warped rotor or an out-of-round drum .
The faces of a disc brake rotor must be parallel.Check the rotors for runout and parallelism. You can often see warp-age in a brake rotor by simply looking at it. A warped rotor should be replaced and is often caused by improper tightening of the wheel lug nuts. In fact, uneven lug nut torque can cause a pulsating brake pedal.Resurfacing the rotor to restore the faces will usually eliminate the pulsation (unless the rotor is bent or is badly worn and has started to collapse in which case the rotor must be replaced).You should be aware that pedal pulsation is normal on vehicles with antilock brake systems (ABSs) when the ABS is working.Pedal pulsation caused by drum warp-age isn't as common, but it can happen. Overheating can also cause rotors to warp. Overheating may be the result of severe abuse or dragging brakes.

Getting this possibilities checked/inspected will help.

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.
