The brakes were working fine with a good pedal. But one front pad was down to the metal. I replaced the pads on both front wheels. As soon as I finished, I stepped on the pedal and it went right to the floor. I soon noticed brake fluid shooting all over the engine, found the brake line from the ABS to the front left wheel was leaking badly. It was pretty rusty, so I suppose when I used a C-clamp to push in the caliper pistons, I blew that line. I replaced the line, and no more leaks.
I have bleed the brakes and bled them some more. Used almost a quart of fluid, making sure the master cyl. did not go dry. I still have no pedal. Or, I should say the pedal goes all the way to the floor, but it does stop the truck, but it's scary driving it that way.
This is the first vehicle that I've had that has ABS brakes. I've never had this much trouble bleeding brakes. Is there some trick to bleeding these ABS brakes?
I should mention that I bleed them by pumping the pedal, then holding it and opening the bleeders, and repeat... and repeat again, etc... (The same way I've always bled brakes on older cars without ABS).
Thanks
