The most common cause of brake pulse is wheel bearings, because the rotor wobbles.
The way to tell is that you will also feel it through the steering wheel, when not applying brakes.
If the rotor wobbles, it will also make the brakes spongey, because the wobble will cause some piston retraction, causing a longer throw when applying.
It is usually the fronts that go bad before the back. And one side before the other, often because a bad seal allowed water in. But you can tell by jacking up and feeling for play.

If not a wheel bearing, then I would consider ABS problem, or the rotor was installed wrong.

My escape is making a grinding sound, along with pulsating when braking. My husband has replaced the abs sensor, and it is still doing te same thing. Any suggestions what to do next?


The grinding sound when braking is almost surely worn brake pads. If an abs sensor is bad it will set the abs light on. Heres an easy way to figure whether to look at the front or rear brakes first. When braking, take notice as to whether the vibration is felt more in the steering wheel or the seat. If it is more in the steering wheel take a look at your front brakes first, and obviously if it is felt in the seat look at the back brakes first. Both front and rear need to be checked out because the pulsating you are feeling is due to rotors or drums that have been heated up and warped. In order to fix both problems, you most likely will need brake pads and rotors/drums. If you just replace the pads, not only will the pads wear away faster due to the damage to the rotors/drums, but your vibration issue will not go away and infact may intensify.

Breaks grabbing and pulsating


brake shudder is caused by thcikness variation of the rotor surface. I would have the rotors machined on the car so they are perfect to your wheel spindle.
The grabbing could be due to low quality brake pads. Use Ford OEM or Motorcraft Value pads.
tascafordparts.com has discounted brakes.

Volvo 850 GLT's brakes??


if the pulsating in the steering occurs while braking this is an indications that the rotors are out of round and need to be turned or replaced. if they are causing a pulsating while driving without braking it could be the calipers sticking.

your back brakes will be cooler than the front brakes as the majority of braking is done ith the front brakes even on four wheel disc brakes. hope this helps.

Anti lock brake system


If the light is not on it may not be the ABS that is pulsating on slow braking but it may be that your have warped brake rotors, even if the rotors were replaced with the pads the new ones may be warped already, we always check new rotors on a brake lathe before installing them because we have seen this happen many times

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.

1 Answer

Brake pad pulsating


Possible causes- low spot on the rotors. Caliper pins not sliding with pulsation. May not need to replace pads.
