The brakes were so bad on one side that the caliper pistons pushed out so far and blew the seals and leaked brake fluid out of it. I was driving when the whole front brake system stopped working and I had to drive it about 15 miles with just the back brakes working only. So it has all new rotors, calipers, pads on both sides now. Then I started by bleeding the front only. Every time I pumped the brake pedal it would go down to the floor and it had some pressure but it would not come up quickly. It comes back up slowly. And when the truck is running there is absolutely no pressure in the brake pedal at all. And the front brakes are not engaging at all.
