    Hey this is for the 4runner Nerd. Brake pedal went to the floor at a 25 mile an hour stop.
    Reapplied brake pedal by returning to normal brake position, reapplied brakes and the problem went away. Has this happened to anyone with 2016 4runner Limited?

    I know of a least 2 other 4Runner owners that have experienced similar issues on another forum....definitely make an appointment with your dealer to get the brakes checked and the issue logged in their system.

    Is plasti-dip a mod?!
    Sounds like a failing master cylinder. Get that sucker to the dealer immediately!! Brakes are a huge safety issue!!

    Crushed the bumper real nice
    Had that happen in my 2014 limited earlier this week. It was -9f on a dry road that had been salted earlier that morning. Went to stop in a 25mph and the brakes did literally nothing. I had ample stopping distance and plenty of traction but when I pressed the brake pedal down it didn’t slow the car, no ABS kicked in, no dash lights flashed or came on after and the brakes started working again after the collision. The shop I usually take our vehicles to said they inspected it and couldn’t find anything wrong with it. It also seemed like they spent less than an hour checking it out (including the test drive). So idk how valuable their input is. I’m going to have it inspected by our local Toyota dealership when they have availability but the whole ordeal is very unsettling. Like DGP1961 said, don’t want that happening at cross walks.

    Many with many more to go
    There are so many variables to any braking system. Add ABS and its even bigger. If your pedal went to the floor, you have air in your system and more than likely is rapped in the ABS module, which means a brake lines, seal in the MC, or seal in one of the calipers has failed. You may not see fluid on the wheel or ground because it is only happening when you you let off the pedal, as it has no pressure, but it is allowing air to enter the system via the faulty seal.

    How many miles on your rig?
    Have you had the brake pads, rotors replaced or pads replaced but rotors turned?

    Here is a video showing how a vacuum brake bleed is performed to ensure no air is in your braking system.
