162000 miles, 2.2 4cylinder. I changed all the brake pads on the above vehicle. (4wheels). I took the lid off the brake resivoir. At each wheel I pressed the caliper in so it would fit over the new pads. The excess fluid spilled out of the resivior.I put it all back together also checking that the fluid level was alright. Now I have abrake peddal that goes to the floor. I bled the system completly starting with the farthest wheel from the mastercylinder. Still have no brakes. Even bled the mastercylinder. Do not know what else to do. Could I have some how knocked the mastercylinder out. I know now that I should have opened the bleed valve on each caliper. Please help with info. Thank you so much

Does the pedal build pressure when pumping it? Does it drop when holding pressure on it?

There is a specific order to bleed:
RF-LR-LF-RR

It may be good to suck out the old fluid from the master cylinder and replace with new. Flush it with the new fluid, running a half quart to full quart through it. You can check the master cylinder by plugging the lines on it and making sure the pedal is rock hard.

You need to test the master cylinder by blocking off the lines with plugs. Once they are blocked off the pedal should be hard, if not, replace it.

Did you try bleeding per my previous post? Make sure the bleeder are all fully closed or air will get sucked back in.

When pressure bleeding this, the person working the bleeders tells the person pressing on the brake what to do. IT should be a slow but constant press on the pedal, not quick. The pedal should never go all the way to the floor or it may tear a seal in the master cylinder.
