My Tacomia truck is always that way..Seems like there should be some way to remove the slack..

If you haven't had the brake fluid flushed, you ought to consider it.

I may have stated this wrong..The brakes seem fine and I dont have to jam my foot into the pedal to stop the car.It just seems like there is extra play in the pedal before it starts apply brakes.Also it makes a sound when you take your foot of the pedal..Even with engine off if you press pedal and then remove foot ,it make a little clunk sound...Dont know what would cause this but did find others on line with the same two problems but no answers for a fix....

Not long after I got my SC in 09. (it is an 06) I had Flow Lexus in Greensboro check out the "clunk" They indicated that all was well. I do not know why our brake pedal clunks, but apparently it is common. It does seem to be different than any other car I have owned. I just learned to ignore it.
Just to be clear. Mine clunks on the return. Not going down or pressing.

For what is worth, the travel on my car is now almost zero after my resent brake pad change. I have not noticed any brake clunk noise either.

I've never had any brake clunck and I've serviced my brakes twice. Maybe the caliper bolts are not tightened completely and the clunk is the caliper sliding back and forth? Or you're missing the brake shims? Or the caliper springs might be installed incorrectly? Also, I helped with my recent Big Brake Kit Upgrade to the Supra TT 4 piston calipers. After we tightened everything up, the mechanic had me jump in the car and press the pedal down and pump the pedal while he bleed the brakes. It went all they way to the floor, then he told me to pump a few times after he closed the valve. He asked if it felt normal. I said it's still a little low. He open the valve again and had me pump while he bled it more. The pedal returned to where I felt it was it's natural position. We did this four times for each caliper. I recommend anyone who feel that there's too much travel, try a brake bleed. Additionally, I do believe you can bleed the brakes without having to remove the wheels, if you have a lift high enough to get totally under the car to access the rear of the calipers. Don't quote me on that, though.

I bled the brakes after I replaced the master cylinder and I removed the wheels. I suppose it is possible to do it with the wheels on, as Shawn stated, and a lift would make it easier.
As for the clunk, I would get the clunk when I would first back the car out of the driveway when everything was still cool. The sound would certainly bother me and I think it went away after the brakes warmed up a little.
I believe there might have been a TSB on this subject but I cannot be certain without looking it up.
