    I have a 2014 TRD Off-Road & was wanting to flush the brake fluid by myself. I've read several threads & I'm a little confused on the best method. It sounds like I have an electric pump in my master cylinder that will pump the fluid out once I open one of the bleeders & press the brake pedal. If I take a hose & attach to one of my four bleeders, submerge the other end of the hose into a jar with some fresh brake fluid, turn the ignition on, open the bleeder & press the brake pedal will this flush that line & prevent air from re-entering the system? Of course I want to make sure the master cylinder reservoir doesn't run dry during the process. Thanks for any help.

    Correct.

    I would say still keep it a two person job as it would be preferable to shut the bleeder as fluid is being pushed out of it by the electric pump. But its not hard for a cute college chick to help you as you tell her, OK push on the brake pedal as you watch fluid getting pushed out the close the bleeder.

    Or use a brick / stick wedged onto the brake pedal, but then the cute college girl wouldnt be all turned on by your knowledge of working on vehicles..... haha

    Lmao! I was thinking of purchasing a Mini VCI cable & running the Toyota Techstream software so I can actuate the pump from a laptop while I'm next to the bleeder. I only have 64bit versions of Windows10 though so I'm not sure if the software will work (I hear you need older 32 bit versions).

    I have the techstream software workin on my windows 7 64 bit laptop without issue. It did take some searching for the right drivers for the cable, but the software itself works fine.

    But really you could put a stick / brick etc to push down on the pedal just enough to actuate the brake lights, then go out and loosen the bleeder, let it flush the line, then close it.

    But i like the idea of a cute girl preferably in little to no clothes helping out.... though id probably get distracted and drain the entire master cylinder getting tons of air in the line.... hahaha

    You should be able to run 32bit software on a 64bit machine, Techstream even lists support for it. However, they do not list support for windows 10. Regardless nd4spdbh's original recommendation is way better.

    The Techstream Software runs fine. The software driver for the cable is the issue.

    I purchased this and was able to do this job all by myself with little difficulty. Just make sure you have a good seal against the top of your brake fluid reservoir. I didn't initially and had a little bit of a mess. But if you keep the power bleeder bottle pressurized with fluid in it, you should just be able to open each brake bleeder nipple and drain until you see new clean fluid. That's what I did 1.5 years ago with no issues since. Some will say this is bad for the ABS system but I didn't buy into that and did this method anyway.

    this will work on the standard vacuum assisted brake setup of the non 09+ TRD OR 4x4. But with the 09+ TRD OR 4x4 we have an entirely different master cylinder that has an electric pump to produce more brake pressure. This pump will actually run constant till the pump sees a cut off pressure. So turn the truck to run and you open a bleeder and simply put a little pressure on the pedal it will actually shoot brake fluid out of the line, no need to suck it from the bleeder itself. If you wanted to do it the old fashion way you could with the ignition off, but why when you have a self bleeding system built into the truck!

    Ah I didn't realize that. Good point.

    Yes - good info above in post #8. From the Motive Products Web Site. See the part in bold:

    Toyota and Lexus- The majority of Toyotas and Lexus models use a reservoir cap that is a push to seal cap. It doesn't screw on or twist to lock. Some Toyotas and Lexus use a cap that has two locking tabs that engage inside the reservoir neck. Both of these types of caps will need to use the Universal Round kit 0101 with adapter 1101. Note - if the reservoir is under the cowl the 1101 will not work. Also some Toyota and Lexus use an integrated master cylinder abs unit where the ABS unit is either directly below the master cylinder or attached to the side. We do not have a kit that works with those vehicles.

    I have the same vehicle as the OP... just wondering, does the TRD OR require that you bleed the lines in a certain order?... for example, some vehicles say you must bleed counter clockwise starting at the front drivers side.

    I did it by myself on my last truck like you described. I used a clear catch bottle and clear tubing. Put some BF in the bottle and stick tubing in the bottle so when you pump the brakes it won’t draw air back in. It was actually pretty easy.
