Howdy Scotty. I'm having a little bit of brake trouble with my 1989 Dodge Dakota. I'll fill up my brake fluid about once a month, and by the end of the month my brakes are scrubbing and the fluid is empty. I can't see any leaks at all, but my brakes always hiss when I press the pedal. My back drum brakes always crank and grind, but I don't have the money to replace them. Front disc brakes work great....when the fluid is actually in there. Is there an underlying problem or have my brakes just gone to hell. I don't care enough about that old thing to do a full brake job, I just don't want to crash and die because of brake failure. Thanks Scotty!
