96 Ram 1500, 5.9, rear antilocks. Early last week, I brought the truck to work, while on the parking lot the brakes went out, blew a line coming from the modulator to the LF wheel at the joint with the flex line, also blew a line at the splitter block on the rear axle going to the LR wheel. Replaced the busted lines/fittings, new wheel cylinder on RR wheel, got the back brakes bled ok, had some issues with the front, especially the LF, brakes worked, spongy pedal, pulling to the right, air bubbling in the MC. Could I have a caliper that is stuck, haven't pulled the wheel yet? I'm using the HF air bleeder, went over them 4 times, in the proper order. the MC did go dry when the brakes went out, 70 mile rollback ride, it's old, researched old threads, it's pointing to a bad MC, picking one up today, will make sure to bench bleed. Am I going down the right path?

 

Jack up the front, try and spin the wheels. Step on the brakes HARD once, then try again. See if they still turn the same.

Spongy is air in the lines. With RWAL, bleeding is pretty straightforward. Sometimes I takes a bit to get all the air out though.
