I decided to take thirty minuets to replace my rotors the other day, and I'm now going into day three of this project.
Let me start from the beginning so you can know what I know. I got my 1999 4.0 auto smoged and when I got in the jeep the ABS light was on I went to the DMV, than to auto zone to pick up new rotors and pads. As I was leaving auto zone the ABS light went off. I put the jeep in the garage and parked it. I had breaks. I got the calipers off, replaced the rotors and soon realized I could not compress the calipers. I pulled both calipers off and took them to my in-laws to use the shop press. I took the calipers apart inspected and cleaned them. I brought them back home and put the whole thing back together.
The pedal now goes right to the floor. I pump it and it has pressure. It sits for 10 seconds and back to the floor.
I have bled all four wheels, the master cylinder, and the ABS lines. (ABS done with ignition on) There is zero air in there. When I pump up the system and hold it keeps its pressure, which is how I ruled out the master cylinder seals. I have bled the whole system four times and not a bubble of air is how I ruled that out.
In the morning I'm going to pick up plugs to plug off the ABS system. My reason for that is there should be a fail-safe; if ABS goes out I should have breaks.
I don’t feel to confident in that. I feel like it has something to do with the ABS. I just would like more ideas thrown out there so I can have a different approach.
