so when i got my 89 supra i knew i bought it with brake problems. i put in wagner thermo qiet brake pads all around that were installed last month and have been worn in. i have earls stainless steel brake lines all around. i changed the booster and the master cylinder. also the old fluid has been completely flushed with new castrol synthetic brake fluid and system has been completly bled. now heres the problem last night it was braking perfect and this morning i got up ready to test them some more and i would smash the pedal to the floor but had very little brake. 5 minutes later the brakes warmed up and everything was working extrodinary. what could be the problem ?
