    Has anyone done the Car Care Nut’s vacuum method for brake fluid flushes? Did it go well with good results? Looks easy enough taking it on solo. Did you do it front passenger, front driver, rear pass. and rear driver? Or back to front?
    Thanks in advance.

    Generally you bleed from the wheel that is the farthest away from the reservoir first, which would be the rear passenger. Next, rear driver. Next, front passenger, and finally front driver. Don't let your reservoir go dry. You'll introduce air into the system, then you start all over. Have plenty of brake fluid on hand.

    I thought toyota specified the pattern in OPs post. Im sure you could do it either way, but I know people here generally prefer to follow the factory suggested procedure.

    Then why ask? I simply used a method that has been tried and true on all of my vehicles since I was a kid. If you noticed, I used the word "generally" which would infer a basic method. Anyway, the method I used was successful, and I did it solo, but everyone knows the Car Care Nut is Toyota God. So, use that.

    Having just gone through a huge hassle using a pressure Motive bleeder, which ironically some say is better than the vacuum method. I would suggest you just do this.. and only this

    Get a few bottles of Toyota DOT 3
    Syphon off what you can from Master cylinder
    Do passenger front bleed, do pump method as per manual
    Do drivers front bleed, do pump method as per manual
    Move the passenger rear, use activated pump, turn on ACC, hold down pedal and flush
    Move to drivers rear finally do the same as passenger rear with ACC on and use pump with pedal

    Now take your wonderful vacuum or Motive bleeder.. put in back in box and save it for..any vehicle other than a 4 runner. For unknown reasons (maybe ATRAC) it just doesnt work. I tried several bottles of fluid, 15psi confirmed, no leaks, good seals.. it just wont work on this truck.

    One-person bleeder bottle, costs next to nothing. I did the same with a Nestea bottle and clear PVC tubing. Only caveat is the hose needs a good seal around the bleeder nipple, so put a ziptie there:



    How to flush. With a 4Runner, the only difference is with the rear brakes, press the start button twice to power on the vehicle electrical system. Instead of manual pumping, hold the brake pedal down a few seconds at a time and let the electronic pump do the work for you. As usual, don't let the reservoir go empty.
