question, i did my brakes the other night on my tc and, all i did was, push the piston back on the caliper, put new pads, and closed the caliper and done! well when i got in the car, i started it, and the pedal went straight to the floor. so i figured, i'll just bleed them and problem solved. well, long story short, i bled all four calipers, starting with the one farthest from the reservoir and NOW it sounds like when i hit the brake, air is being pumped through the lines, or there is a leak. here is the interesting thing, it sounds like it's coming from the ABS...

now, the car stops fine and everything, but when you push the brake, it doesn't get harder as you push it, it's like one slow descent to the floor. i'm going to take it to Toyota today, multiple people said it sounds like it has a vacuum leak, just thought i'd ask you wonderful intelligent people first. thanks for your input ahead of time.

I am sure you did it, but did you make sure you kept enough brake fluid in the reservior when you were bleeding the brakes?
yes i did, i kept it full at all times.
was this 1 man job or 2?
2 people.
I did the same on the Solara but I pumped the brakes to get them back to right. It always goes to the floor cause the piston has to go back out until they are tight again. I think you might have bleed them to soon, but I am no expert and you didn't day if you did or not.
what do you mean bled them too soon?
When I did the brakes on my CS I had air-in-line issues. I had to bleed the brakes several times all the way around. What helps it go faster is to have the person working the brake pump the pedal several times before you open the bleeder. Have them keep pumping the brake till they can feel pressure build under the pedal. Then release pressure via bleeder valve. Do this in the order you were doing, starting furthest from the BMC.

CS of course does not have ABS, I have done brake jobs on cars with ABS but never had that issue.

Good luck and I hope my .02 helps.
Did you bleed them before you pumped them back up? That's what I meant by too soon and I have heard someone say to bleed in an X pattern. May have to do it twice.
i took it to my mechanic up the street, he bled them all, he says it might be a faulty master cylinder. i'm going to take it to toyota and say...it did it when i woke up this morning.... :p

You bleed them by starting from the farthest from the brake master, to the closest. so, rear passenger, rear driver, front passenger, front driver.
you have abs?

you never push fluid back from the calipers when you have abs,,, you should open the bleeder and push old fluid out of the bleeder cause you can get crap in your abs!!!!!!!

No mk2 has abs. It was misinformation on his part.

it has abs not hiss supra and to who did the brake job you may have messed up your abs!!!
i did the brake job. i thought i had to bleed the brakes, turns out i didn't have to bleed the brakes. now i believe there is air in the system. getting out has turned out to be a task. i'm going to go home and tinker with it some more.
