I'm new to this site and learned much already. I hope someone out there can help. I was towing my RV with my 96 2500 2wd V-10 when the trailer brakes went out. The trailer weighs 10,000. I was ok because I was on the Xpress way. (no stops) So I thought till a lady cut me off and I had to hit the brakes hard. After that I had the ABS and BRAKE lts come on. Was told I boiled the fluid. I changed the fluid and bled the brakes. No change. Sometimes when you step on the peddle it makes a gurgling noise. Sometimes the light doesn't come on till this noise is heard. If someone could help me it would be appreciated.
