    Hello, I"m a new member & owner of a 07 Crewmax Limited w/ 92k miles. The Tundra has new Rotors & Pads, and new tires. I'm getting an intermitent brake pulse, sometimes there is no pulsation at all and other times it feels like the front end is coming apart. I've taken it to the local Toyota dealer and the say its just a cheap set of brakes. They found nothing that raised conern, however the brakes were'nt pulsing at that time.
    Fortunately, the dealer I purchased it from is obligated to fix the "front end shake" per my purchase agreement. So far they have just turned the Rotors. I've had the truck for 2 weeks and I'm bring it back again today.
    The truck isn't covered under any TSB and I'm at a loss as to what could be causing the problem. Thanks for any input.

    Hmm, have them check the pistons. Sounds like maybe you have a piston that is sticking.

    On my way in now, i'll mention that, plus any other suspension or front end parts that may be worn. hoping for the best.

    Toyota uses a special set of O rings that go between the calipers if those are worn itll cause pulsating!! Other times the brake pedal will actually push right back at you!! They sell a complete rebuild kit for the calipers but wont sell just the O rings!! (Safety item) If you feel comfortable with what you see you can match a set of O rings at any Hydraulic supply company!! Id rebuild the calipers personally! Good luck!

    What speed are you slowing down from that causes this vibration? I'm wondering if you are only getting the pulsation from higher speed stopping and not when you have slower speed stops.

    There is a TSB for the backing plates for older trucks that are 12' and older....FYI. This helped with cooling.

    Oh, one more thing. When was the tires balanced last?

    My truck shakes like that when I need a rotation and balance.

    Some Mods :) See build thread for details
    Most common for braking vibration is the rotors. Since they turned them it could be the pads being worn irregularly.
    I would have them replace rotors and pads with new Toyota OEM.

    Tire balance and tire wear can cause vibration but not just when slowing down.

    The calipers that were mentioned before could be another reason. Rebuilding them would be cheapest. Replacement with OEM if they dont repair.

    Oh and welcome!!

    Turning brand new rotors....Just shaved unnecessary life off of them. I'd have them replace the rotors with new rotors. Especially if the rotors weren't the issue. And if they were, make them replace them.

    Update..... Dealer put a new caliper on the drivers side, turned the rotors and balanced the tires. So far so good.
