DIY for Replacing Brake Fluid?
Does anyone know the procedure to replace the brake fluid on the 2013 Lexus GS 450h.
I read somewhere that you need Toyota Techstream to replace the break fluid properly for this vehicle. Is that necessary?

Sorry for the poor copy/paste below but this is the procedure and it says "damage may result" if you don't use Techstream, but haven't done it yet. Hopefully the instructions help you:

Bleeding
NOTE
Move the shift lever to the P position and apply the parking
brake before bleeding the brakes.
As brake fluid may overflow, do not leave the brake fluid
can in the reservoir filler opening when adding brake fluid.
Bleed air while adding fluid to maintain the fluid level
between the MIN and MAX lines of the reservoir.
Do not allow brake fluid to come into contact with any
painted surface. If contact occurs, wash off the fluid
immediately.
When bleeding air, select the suitable procedure listed
below.

Loosen the bleeder plug of the front disc brake cylinder RH.
Repeatedly depress the brake pedal and bleed the air from the
bleeder plug of the front disc brake cylinder RH.
NOTE
Add fluid as necessary so that the fluid in the reservoir
does not decrease below the MIN level.
After air is completely bled out, tighten the bleeder plug while
depressing the brake pedal.

According to those instructions you bleed the brakes starting with front passenger side, then drivers side, then rear passenger side, then rear drivers side.
The is the total opposite of what I thought the bleeding procedure was. I guess your pushing all the old fluid out starting with the front passenger.

Whats the procedure?
1) Top off reservoir with new fluid.
2) start with front passenger side open bleeder, pump brakes, while adding new fluid to reservoir.
3) do drivers side, then rear passenger, then rear passenger

Don't you have to bleed the brakes to replace the fluid?
Whats the procedure?
1) Top off reservoir with new fluid.
2) start with front passenger side open bleeder, pump brakes, while adding new fluid to reservoir.
3) do drivers side, then rear passenger, then rear passenger

Brake fluid is hygroscopic, meaning that it attracts and holds water. Water in your brake system leads to corrosion of the master cylinder and the wheel cylinders. Corrosion leads to loss of pressure and ultimately, failing brakes. Look at old brake fluid that's never been replaced; it's dark brown compared to the near clear of new fluid.
Brake work is generally pretty easy; so easy in fact that most folks skip some important maintenance steps that have no immediate payoff. This is one of them. If you're gonna do it yourself, do it right.

If the GS hybrid is anything like the prius brake by wire system, then you'll have to follow a specific set of instructions just to do a brake fluid service. If you don't have Techstream, you must first put the vehicle in "invalid mode" otherwise you won't be able to get the fluid out. Also, on the prius, the fluid reservoir can't be filled to max, or it leaks. I did this a few years back I think....
I usually change out the fluid every 2 years

Brake fluid should be replaced every 3 years as it absorbs moisture quite easily. I recommend getting a Motive Power Bleeder as it makes bleeding the brakes on any car a breeze. If you have a power bleeder it will take you longer to raise the car than it will to do the actual service. I was able to change the fluid on my wife's car (GS350) in less than 15 mins using a power bleeder, they are a life saver.
