Re: Brake warning light on....CJ
Sounds like more than one problem.
The front brakes sound like you have a caliper (or 2) sticking. There will normaly be a slight drag on disk brakes, but it should not be "hard to turn". If the outside is tight, check your caliper slides. If you pry your caliper outboard a little, it should compress the piston. Then you should be able to move the caliper in and out on its slides.
The leak sounds like you might have a bad master cylinder. Which would also turn your light on. Check behind the master cylinder where it mounts to the firewall (or booster if you have power brakes) see if it is wet or if the paint is soft and bubbled up. Brake fluid will soften the paint. So even if there in not obvious fluid there, it will effect the paint. Also if not power brakes, check inside where the pushrod goes throught the firewall. Look for leaks around the boot or streaks on the firewall where fluid has run down.
One other thing I just thought of on the light. The same light is the idiot light for the emergency brake. Check the switch to make sure it is plugged in and is getting a ground when the E-Brake is off. This is a spring plunger switch up on top of the e-brake assy behind the dash. If in doubt, disconnect the wire to the switch and ground it to see if the light goes out.
Good luck. I hope you find your problem(s) before it finds you.
