Ok, so real fast I have a 97 SC3 and it has 94 LS400 front brakes. I changed my master cylinder already and everything was running fine. Until now, it seems like the brakes are being applied when I have my foot OFF the brake..... its not costing far and when I come to a stop it doesn't roll forward (auto trans). When I bled the brakes with changing the master cylinder all the air came out. My question is; is there a way to adjust the pedal or is there something else I should/need to do!? ![Egads!](https://www.clublexus.com/forums/images/smilies/pat.gif)
Also the car is shacking and the shifter is vibrating like crazy when I feel the brakes are messing up

Sounds like a stock piston in the caliper. I would take the calipers off and see if you can easily push in the pistons, if one is stuck, it will be really hard to push back in. If it is indeed a stuck piston, you will just want to rebuild the caliper. In fact due to the heat a stuck piston will generate, you may be able to tell which caliper it is by looking at the brake pads, and/or rotor to see if you can see any discoloration or odd wear marks.
Hope this helps.
Thanks,
Rick

Adding to what scoobySC3 said, you can also try touching your calipers after a drive. If you have a stuck caliper, you WILL notice the difference in heat. The stuck one will be much warmer. Seeing as it is summer now this method may not work as well as scooby's, but it is yet another way to check.

This might be weird or just some bs with my dumb luck but I drove the car to work yesterday and it was fine and once I left for another job it started the same crap with vibrating like crazy. But once I left the car for an hour and drove it again it was fine and seems to be fine since then? I'm thinking I should just replace those calipers to avoid future problems. Thanks for you guys impute

when calipers get shot this happens. the best way to find out is to look at the brake pads, usually one will be more worn than the other. you may also have a bad master cyl or bleeding issues
