OK, I have changed my brakes pads for years and I've never opened the bleed valve when I've used a clamp to push the piston back. I was never taught that! Is that new since we have ABS nowadays? That may explain my spongie brakes on both vehicles! Is there anything I can do now besides have them bled at a brake shop somewhere? Is there a code I need to look for.
I was searching for "master cylinder" because I thought that was the issue...
Thanks,

j cAT - No need to respond. I just read your bleed procedure on another thread. Thanks!
