Not as far as I know. I read of someone who did a bleed using traditional method and got warning lights on dash and squishy pedal. Makes sense, since the brake pedal is not mechanically connected to a booster a la a conventional non hybrid vehicle, since braking is sometimes needed when the engine is off, so there would be no vacuum assist.

Now, I 'suppose' you might be able to bleed if you left the vehicle in the 'on' position and pumped the brakes, as this would conceivably run the pump that creates pressure for the braking system. However, this is not the procedure laid out in the service manual. The manual instructs one to cycle the pump using the Lexus computer (the handheld one that plugs into the OBDii port) to properly bleed the system (it's still bled via the individual wheel bleed bolts, but the pump must be run to push the fluid out).

Hi Lemon,

Regarding your statement on changing the brake fluid, I have a pump that I have used on my non-hybrid vehicles (Civic, highlander, and Ford). With this pump, I can put the brake fluid in and pump fluid through the break master cylinder. Then, I open the bleed nuts (one at the time) until I see the clear fluid coming out. I am wondering if I can use this on the RX 350 hybrid.

Thanks,

John
