Should I replace all rotors?????
Hello been a Lexus owner for about a month now
I'm trying to get rid of this vibration when I brake from 60mph down I was told that this is a sympton of a warp rotor do I have to replace all four or just the front two I was also told to get some steel brake lines, when I press my brakes they go to the floor seem like but if I pump them a few times they will get hard.
What do you guys suggest

You know this post and the other one, it may be true that your brake booster is failing. You don't need SS brake lines, unless you are hard core driver. I am pretty hard on my brakes, and I don't really want SS lines. You can acheive great brake feel with good pads and nice DOT 5.1 fluid.
If you get the vibration at 60, in your steering wheel WHILE BRAKING, than it could be the rotors. But you should see about getting them cut before replacing them. It is most likely the fronts also. If they are out of spec to get cut, then just replace them.

Hrm..for the brake feel..it might just be a case of bleeding the brake fluid. My brakes were like that too (well right after i changed the rotors) and then I bled the brakes. Now I can finally stop better and will probably bleed the brakes again just incase I didn't get all the air out the first time around.

Yea, thats what I would recommend, but he has another post with an issue with the booster and abs supposedly. It never hurts to bleed them.
Actually, isn't there a special procedure, like the ignition has to be on or something? Then you bleed them in order from the firthest wheel to the closest wheel? I never did this on the GS, but I might eventually.

yup. gotta put it in the ign ON position in order for the ABS valve to open up. But keep in mind it that it can quickly drain your battery so it helps if you have someone there to help you do it quickly, or turn on your engine for a few minutes after you bled two brakes.

Agreed, try bleeding it first.
As for the vibration, could be a couple of things. Could very well be that the rotors are warpped, depending on how bad it is, you can get them cut and reuse them. Other then that, a slight vibration can also be contributed by failing tie rod ends, etc. I think I'd stick with checking out the rotors first though.
