    Brakes still pulsate after new pads and rotors-2002 Escalade

    The brakes on my 2002 Escalade were pulsating when I was slowing down from highway speeds. I replaced the rotors and pads and it helped a little bit, but I can still feel it. Could the calipers need to be replaced? I do not know if they have ever been worked on or not.

    Thanks

    Possible rust or debris between rotor and hub

    I think I cleaned the hub very well before I installed the new rotors. How can I tell if I have a bad caliper?

    The caliper will either leak or get stuck when bad, question, is the steering wheel shaking when braking or is it a pulse like the brakes are be applied on and off

    I hate to threadjack but my truck does the later in the rear where it feels like the brakes are plus ring on and off in rapid fire movement (I think its my rotors as I put new brakes on the rear not too long ago and it still does it)

    No prob... Yeah if its in the steering wheel its most likely the front if you jus feel pulsing like a slight on and off the brakes its most likely the rear

    are you sure your not just feeling the abs kick in? abs has a pulsing feel to it because the caliper is opening and closing at a rapid pace.

    Did you replace the pads and rotors on all 4 wheels?

    Its a very smooth pulsing not as violent as abs

    Should be mostly when the rotors get hot , like aggressive braking or hi speed braking

    Maybe a caliper is not completely releasing, causing a rotor to overheat and warp.You can check for this condition with a non-contact infrared thermometer. both sides on the front should be close to the same temperature and both of the rears should have similar temperatures.

    When the abs does engage it sounds like rapid fire pulsing from the rear instead of smooth braking(my dads h2 is smooth braking)
    I told the service manager and he said it sounded like I have a warped rotor

    I know warped rotors are caused by heavy excessive breaking(I rarely have to panic stop unless someone stops sudden and I have to avoid hitting them)

    I have heard if you ride the brakes a lot it does this(I don't but who had the truck before may have))due to warping the rotors

    Rotors don't "warp". Excessive runout is caused by uneven wear.
