hey guys! need a little help. My wife's 2002 LS 430 brake pedal stops car almost on the floor. Installed new pads and rotors all around and a new master cylinder. Bleed from Master cylinder. brake pedal still low. should I bleed at the wheel or is there something I'm missing. Thanks for any help.

Bleeding the master cylinder does nothing to eliminate air in the brake lines. Suggest you bleed each wheel cylinder.

haven't used mine yet, but it was recommended here. Need the hose, nipple, and an automotive adapter...

btw this is what I ended up assembling, to connect up with the Motive bleeder. Did you have any trouble getting your rear rotors off? I'm planning to use bolts through the holes to force them off (M8x1.25)....

I didn't have any problem with the removal of the rotors

I agree with bleeding all the brake fluid lines. In addition, out of an over abundance of caution, I would then take the car out to an empty park lot (or empty stretch of roadway) and slap on the brakes a few times to get rid of any air pockets you may have already introduced into the ABS plumbing. After that, bleed the lines again to rid air pockets you pushed out of the ABS.

If the antilock brake solenoid block is similar to LS400,(has bleeder screws) then you require a special tool to evacuate air bubbles.
