    Just got my new 2009 Tacoma DC TRD Off Road in Magnetic Grey.
    What a great truck. Loving everything about it but the squishy noise
    that the brake makes when pushing it down. Is there something that can
    be done about that noise? I test drove 3 trucks and they all did it.

    AHA! Another one! Mine does this too, but didn't do it till 5 days after I brought it home. Have not had a chance to have it looked at yet. If anyone has a fix, post it here so we have something to go to the dealer with.

    Maybe it is a Grey thing as mine is MGM?

    I've noticed that too and the squishy brake feel but only on the 2wd's. My 4x4 brake feels more solid than my cousin's 2wd. I believe it's just the way it is on these trucks.

    This is a "squishy sound", not a "squishy feel".

    Step on a fat fish that you just pulled out of a lake. That is the sound it makes.

    I have the same truck with the same noise. (talking out of my ass here) It does have an active brake control when you hit the brakes in a panic it applies more braking power could have something to with it. I hit mine in a panic today and the pedal got real hard and I dont think the noise was there. I dont know if this is whats up its just what I think.

    I know what you mean about the "squishy" sound. It's likely the vacuum assist that you're hearing.

    The "squishy" feel has me more concerned ... maybe it's too many years of driving euro cars ....

    Unfortunately, the squishy feel goes with the squishy sound. All the 2wd I drove were the same.

    I don't like the feel of the brakes either. Squishy is a good word. No sound though. 09 4x4

    So I decided to take the truck in to the dealership and have them
    try to fix this squishy brake sound. The service advisor could not believe that this sound passed through Toyota quality control. But unfortunately at this time there is no fix. Even the tech thought that it was annoying. They test drove another 2009 Tacoma and it did the same thing. Which I did the same with 3 other trucks and all were the same. But
    until Toyota comes out with a TSB for it the service department cant
    mess with it. I guess if we get enough people calling Toyota customer relations they may look into it further. They were saying that the sound is
    coming from the Brake shaft boot? May have to do with the electronic brake force distribution which is new on the 2009 model. I had a 2006 Tacoma and it didnt make the sound. I am surprised that there aren’t more people complaining about it.

    The following applies to the non-vacuum boosted toyota trucks and is considered "normal" behavior of the system:

    The "squish" is a byproduct of the vehicle dynamic control unit valving (or whatever jargon toyota uses for their brake based stability control). It afflicts other toyotas, not just tacomas, but the tacomas seem to suffer the worst brake feel when compared to other toyota trucks. Many believe it is because the tacoma uses rear drums where other trucks use 4 discs. Another byproduct of the system is a mechanical whirring/pump sound as the hydraulic collector recharges (to hear it pump your brakes with the key in the "on" position without starting the engine). In some trucks this motor running can be felt as a faint buzz in the pedal. Finally some will have noticed that their trucks will roll in the summer when the AC kicks on - This stems from the panic stop proportioning the system does, basically you apply just enough brake to hold the truck still but when the AC kicks on torque increases overcoming the brakes.
    The system has some problems with heat dissipation which people who have used the hill descent feature will have learned the hard way.
    All in all the system is not bad but it is less refined that of other manufacturers and I suspect there will be some major improvements going forward.
    For tacoma drivers it is important to use your parking brake pedal frequently as this helps ensure the rear drums stay adjusted.

    Driving in traffic this morning. Every time I stop .....Squish squish squish. This sound is very annoying. Talk about design flaw. I cant believe this slipped by Toyota quality control! Hopefully Toyota will come up with a fix!

    my 2009 does the same. It really drives me crazy. Took it in to the dealer. The dealer, of course, could not hear any noise. Looks like i will always have to have the radio on to drown it out....
