I have a 1996 lexus es300. I'm replacing the front brakes

Customer Question

I have a 1996 lexus es300. I'm replacing the front brakes and flushing the brake lines. I had the brake calipers off, and I started to flush the brake lines starting with the rear right wheel. However, I forgot to clamp in the front, and so when we pumped the breaks the piston of both front calipers came out as well as fluid all over the floors. I didn't even notice at first because although the calipers were off, I just had them hanging by a wire, and had the tires on because I didn't have jack stands until today. I put the piston back in and put c clamps on, and continued to bleed the rear right until I saw clear fluid coming out without bubbles (well there were some tiny tiny tiny little bubbles but it was 99.9% nothing, and I was going through alot of fluid). Then i went to the rear left side and repeated process. Now, with the front calipers still clamped and the backs bleeded I got in the car and pushed down on the breaks and it goes with some stress but goes all the way to the floor. Does not feel pressurized?

Have you bleed the front?

well i guess inadvertently because i blew the pistons out because the calipers were unhooked and not C clamped.

Hello. Welcome to Jsut Answer. Please allow me to assist you. As I understand the basis problem, you bled the brakes without benefit of the caliper being in place over the rotor, is this correct?
