I HAVE A '92 DODGE DAKOTA 3.9L V-6 4x2. I HAVE A PROBLEM WITH THE BRAKE SYSTEM. IT IS LOOSING BRAKE FLUID CAUSING LOSS OF BRAKES. WHEN I FILLUP THE RESERVOIR AND PUMP BRAKES (NO ENGINE ON) THE PEDAL IS ROCK HARD. WITH THE ENG. RUN RUN'G, I GET A MUSHY PEDAL. IF I PUMP SEVERAL QUICK TIMES IT HARDENS BUT WON'T HOLD. I PURCHASED A NEW "CARDONE-TYPE" MASTER CYL. THE OEM HAS A RESERVOIR ON TOP OF THE MAIN UNIT. IT LOOKS AS IF IT IS "PRESSED" INTO THE RUBBER "SEALS" ON TOP OF THE MAIN UNIT.
I START CHEAP TO RESOLVE MY ISSUES. I HONESTLY SUSPECT THE BOOSTER BUT IT IS $119 USD & UP.
WHAT I NEED TO KNOW IS HOW TO REMOVE THE RESERVOIR FROM THE MAIN UNIT. THE REM'D UNIT I HAVE HAS THE RUBBER SEALS AS DOES THE OEM. I TRIED PULLING IT OFF BUT I DON'T HAVE THE STRENGTH. I THOUGHT ABOUT "PRYING" IT OFF BUT STOPPED THERE IN CASE THIS IS A "NO-NO"!
I NEED ADVICE HERE FOR REMOVAL AND ANY INPUT ON THE BOOSTER'S RELATION TO MY SITUATION. I HAVE NOT NOTICED ANY LEAKAGE FROM THE BOOSTER THAT IS EVIDENT. THERE IS A LARGE "WET DISCOLORED AREA ON THE FACE OF THE RUSTY BOOSTER-AROUND THE AREA WHERE THE CYLINDER MEETS THE BOOSTER BUT, I'M NOT SURE IF THE MAIN UNIT CAN LEAK AT THE PISTON.
THANX FOR ANY INPUT.

Why are you changing the master cylinder? Has it been determined to be faulty? Where is the system leaking from?
You obviously do not have near enough experience to be working on a brake system and you could end up killing someone with that car. You need to leave the brake repairs to the professionals and stop experimenting with something as important as a brake system.

You have a leak to find and if master cylinder wasn't leaking at rubber connections to a tank or down the brake booster it really can't leak anywhere else from it. That's not the "cheap" way out, finding the problem/leak and fixing it right the first time is. At the age my bet is a rusted brake line.
BTW - Accidents aren't "cheap" and can as we know be deadly,

posted in our email:
I HAVE BEEN WORKING ON CARS (ENGINES, TRANS., TIRES, BRAKES, REAR ENDS, ETC) SINCE I WAS 12 YRS. OLD.......52 YRS. AGO. I DO HAVE A REASONABLE KNOWLEDGE ABOUT THE INTERNAL COMBUSTION VEHICLE.
I CHANGED OUT THE OLD MASTER CYLINDER ABOUT 0230 THIS MORNING AND DECIDED TO WAIT FOR DAYLIGHT TO BLEED THE BRAKES. I BLED THE BRAKES (FRONT FIRST AS MY KNOWLEDGE HAS TAUGHT ME). I ALSO USED THE BEST METHOD (AS MY KNOWLEDGE HAS TAUGHT ME)-BLEEDER HOSE IN A "CLEAN" CONTAINER OF BRAKE FLUID ATTACHED TO THE BLEEDER SCREW. I GOT A FIRM/HARD PEDAL. I DROVE IT OUT THE ROAD AND TRIED THE BRAKES 10-12 TIMES INCLUDING 4 "PANIC" STOPS. THE FRONT WHEELS LOCK UP. IT HAS ANTI-LOCK BRAKES BUT THE ANTILOCK DOESN'T WORK ON THE FRONT.
WHEN I GOT BACK I CHECKED THE LEVEL IN THE RESERVOIR, IT WAS DOWN ABOUT 1/4" FROM THE INITIAL FILL-UP-WHICH IS GENERALLY NORMAL AFTER WARM UP AND HARD USAGE.
AS YOU CAN SEE...THIS OLD MAN DOES HAVE SOME "EXPERIENCE". I WILL NOT CLASSIFY MYSELF WITH YOU ASE GURUS BUT, I DO KNOW HOW TO SAVE MONEY AND "GET THE JOB DONE".
THANX AGAIN FOR YOUR ADVICE.
ED.

Stuff like that comes by a lot still. Most of if we saw that would be fast as we could to call that all wrong. You have to hope surfers don't get something like that without at least a response to negate that as any way to do brakes or the bleeding. About the worst thing readers you could do is pound on a new part right away like that one said.
Great to see you around carjunky - Tom

Yep, a lot of inaccurate statements in that response.
