my kid has a 2001 jeep Cherokee 4 wheel drive that suddenly started leaking brake fluid from the fittings on the abs module, he said it started after he had a oil change at jiffy lube, any of you have or know someone who has run into this problem?

 

Sounds like something could have gotten hit or knocked into when they were working. Pictures would help.

 

Maybe what Red1992XJ said. I tuned up a '96 I used to own. Dealing with the spark plug in cylinder 6 I kept bumping the front passenger brake line. Got her all tuned up, started her up, and she sounded fine. About an hour later I start her up to go to work, put my foot on the brake to put the Jeep in drive, and the pedal went to the floor. The line was rusty enough that bumping it a couple times caused it to fail. Since the abs module in on the driver's side maybe when they were checking the air filter they bumped to line a couple times.

 

Here's my suggestion:
