Brake fluid leak

I had to replace a brake line and the line I used already came preformed and flared. But where the line connects on top of the ABS module I'm getting a very small amount of fluid coming out around the threads. Does the fitting and line just need to be adjusted or how can I correct this? I did flush out the old fluid in every line and I did bleed the air out at each wheel starting with the farthest one from the module. Also, how is the parking brake adjusted? When it's applied only my right rear wheel will lock up and the left rear will still spin freely.

Hi and thanks for using 2CarPros.

Are you able to tighten the fitting any more? If it is leaking around the threads, either it's slightly loose, the line is deformed, or the nipple inside the cylinder is damaged. If tightening it doesn't help, you need to remove the fitting and inspect for nicks or any evidence of damage.

As far as parking brake, here are the directions for cable adjustment. See picture 1

PARK BRAKE CABLE SERVICE/ADJUSTMENT
1. Adjust the rear brake shoe.
2. Apply and fully release the parking brake six times.
3. Verify that the parking brake pedal releases completely.
Turn ON the ignition. Verify that the BRAKE indicator lamp is off.
If the BRAKE indicator lamp is on, ensure that the parking brake pedal is in release mode and fully returned to stop. Remove the slack in the front parking brake cable by pulling downward on the cable.

4. Raise and suitably support the vehicle.
5. Adjust the parking brake by turning the nut on the equalizer (2) while spinning both rear wheels. When either rear wheel starts to drag, back off the nut one full turn.

IMPORTANT: If the rear wheels rotate during the following test, adjust the parking brake shoe.

6. Apply the parking brake to four clicks. Inspect the rotation of the rear wheels:
The wheels should not rotate forward.
The wheels should drag or not rotate backward.

7. Release the parking brake. Verify that the wheels rotate freely.
