Is this something that could have happened when I pushed the caliper pistons in?? I kept the reservoir cap on when I did it, but did not think that would matter. If it is blowby, how do I find out for sure and how do I fix that?? Will I need to rebuild the master cylinder??? This is starting to get complicated. Brakes worked fine before I changed the pads...

 

When you pushed the pistons back with the system closed that fluid/pressure had to go somewhere. Could have caused issues in the master cylinder for sure. Is the "pedal to the floor" a repeatable thing every time?

 

Yes...Seems it goes to the floor every time...I did not drive it yet, but fear the worse...Di I drain the entire system and refill? Or do I need to increase my credit card limit.
Can I save my master cylinder and is it something I can do???

 

Frank, Go to the line furthest away and open it up, should be the right rear, have some one push the pedal to the floor then lock the bleeder. See what kind of air you have and pressure. It should shoot out, keep a rag in front of the bleeder. Do it with the motor running if possible.
If a dribble is all you get, the a master rebuild or new one is on your list.

Ouch. If I bleed the entire system, will that possibly fix the system? Can I rebuild the master cylinder myself or is it very complicated?

 

Please wait before opening the brake system. With the engine running, try a few sharp pumps (jabs) on the brake pedal. To clear the ABS fault, try a few trips forward and backward in your driveway or such (common fault when cleaning the ABS sensors). Well worth just trying first for free. Good luck.
