Just came back from a vacation where my Jeep XJ sat for almost 3 weeks. Noticed that the brakes were mushy. 2 days later my brake light came on. Checked the brake fluid - totally dry. Refilled.

Here is what I think I should be checking for next.
1. Leaks in brake lines
2. Brake fluid leaking out near brakes. - none so far
3. Master cylinder - already checked - appears to be no leaks

So here are my questions.

1. Do I need to bleed the brake lines?
2. Is there anything else I should be checking?

Thanks in advance

 

REfill your mastercyl and bleed the brakes all four corners, have an assistant push the brake pedal while you watch for leaks

 

also check the rear weel cylinders i just had this happen to me recently ware i had no brake fluid its a 10.00 part at parts store

 

Had a wheel cylinder lock up on me!! destroyed the new shoes i put on and the drum!! all for 10 bucks...i now replace them on all my vehicles with over 100K when i put on new shoes....
