    I had a 2002 Toyota 4Runner in the past (a long time ago), but recently purchased a 2015 Toyota 4Runner SR5. I noticed that when I push in the brake pedal I hear a lot of air. I have taken it in to be checked & was told the brakes are in perfect condition. Is this something that is normal for the 4Runners? If not, anyone know what causes it & how I can fix it?

    being a vehicle with some miles on it very possible the brakes need to be bled and possibly the brake pads are worn down . the air in the brake fluid and/or worn brake pads will cause more pedal travel and this sound .

    with the brakes bled and new pads the pedal should be high and firm with little if any sound/pedal travel.
    when the pads are replaced the caliper pins should be lubed with a silicone grease many mechanics will not do this . if not done the pedal will require more effort to get the brakes to apply and cause the pads to wear faster .

    I will take it back in then. I had Firestone do a complete brake check & they said that the brakes were brand new & didn't need replacing. Guess I will try someone different this time.

    I hear air hissing type of noise too when I de-press the brake pedal...like when pumping air into a ball. Is this what you're hearing?

    I just googled this but I'm not yet 100% sure it's describing the same issue as mine.

    That's it exactly. Annoying sound. I like to drive without the radio...gives me time to think. Guess that won't be happening anymore because the radio will be full blast. Lol

    Mine does that too, brakes like a champ, but the noise is noticeable when it's quiet. I honestly think it's normal, but have if you are still under Toyotacare or whatever that is, have them check it out and report back to us.

    Totally normal. My '14 T4R Trail makes the same noise and I've had the dealer look at it several times...

    My guess is that because it's all "by wire" that you're hitting it, and the brake booster is activating.

    Normal.

    Wait till the first time you do a quick change to brake from acceleration and see how it like to panic stop for you. The computer aided braking takes a bit to get used to.
