2000 Dodge Stratus Breaks 2k Dodge Stratus

Hello guys,

Just want to ask I recently had to change the wheel cylinder on the driver's side rear wheel. I noticed fluid collecting over night in the driveway so I replaced both cylinders. The breaks would not hold pressure after bleeding the breaks. I changed the master cylinder and the breaks worked fine for about three weeks. Now when the car does get driven pressure builds up and locks up the front breaks with out stepping on the breaks. I've bleed the break and come to find out that there is no fluid coming out of the rear break line on the drive side but there was before I changed the master and wheel cylinder.
