94CutlassSLCoupe Posted February 11, 2006 Report Share Posted February 11, 2006 yeah usually in my experience the hard lines rust out near the fuel filter before anything else goes... Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted February 12, 2006 Report Share Posted February 12, 2006 I had one of the lines running to the front wheels rust through and leak. The idiot mechanic who initially looked at it said "bad news.....I can't find any leaks, it's the mastercylinder". :shock: I'm like NO! I just got this damn thing! I just kept refilling it for a while. Then one day, I got curious about where it was dripping from. A friend met me at work, and before we left the parking lot, I told him to hop in and press the brake pedal. I was looking at the lines, and sure enough, the first one to you (if you're standing in front of the car) started gushing fluid out where the rubber over the metal ended. $40 later, I had a new custom line made (along with a few other minor repairs while he was in there), and all was good.

Prospeeder Posted February 12, 2006 Report Share Posted February 12, 2006 Lines, porportioning valve, or master cylinder, usually in the back Quote Link to comment Share on other sites More sharing options...

Jeff M Posted February 12, 2006 Report Share Posted February 12, 2006 Ummm, I still don't see anything stating which end of the car has the leak showing :? If its in the rear than proportional valve as was said, if up front then again as was said, rusty brake lines, but I will add that the rubber grommets that go around the ABS Solenoid and seal them to the fluid resevoir can get kinked and let fluid go past. Last and hope this is not it, the casting that holds the ABS pump motor, pressure switch and accumulator can have a crank in it, Prior addressed this with a top-notch fix, to make a new housing out of billet aluminum 8) just wish the old geezer that owns Prior had not jack the price of this unit up so high, really no reason for it, it was $350 to $400 for a while, then a little bump in price, then a stupid high jump in price come on, "most" people that buy a 15 year old car don't have that much money for such parts, at times the price (GM is the best example with their price being $3,200 for this ABS unit) of the part is more than the owner paid for the car, idiot is pricing him self right out of business with these PM III ABS Units Jeff M Quote Link to comment Share on other sites More sharing options...
Jeff M Posted February 12, 2006 Report Share Posted February 12, 2006 Oh yea, when pulling the ABS Unit, carful the brake light switch on the firewall inside the car, break that and you will be grumbling way more Also you only need to take off the 2 nuts or bolts (can't remember right now) to take off the ABS Unit, no need to do the 4 behind it that are much more work to get at! There are no rebuild kits for these, I have one that I will never let go but GM discontinued these long time ago, not sure where Prior gets their rebuild kits but if someone is good and has the contacts, sure there are ways to find all the o-rings, seals and springs to make a kit up, maybe since GM no longer offers the rebuild kits then the lock on selling them to GM only is gone so he gets them that way. Kind of my hopes someday when I get time to try and duplicate the rebuild kit's parts too 8) I hope . Do the accumulator while you are there, these are common to fail, and about the only common part to fail on these . They last about 4 to 6 years so, do it now and be happy you did for the next 4-6 years 8) . Good luck!! Jeff M Quote Link to comment Share on other sites More sharing options...
Bossman429 Posted February 12, 2006 Report Share Posted February 12, 2006 I wonder how hard it would be to imitate/duplicate that billet housing. I mean, if prior can make them, you would think any reputable machine shop would be abole to mill out something similar. What else would be in a PMIII rebuild kit besides an assload of o-rings? Pistons and such? new solenoids? Quote Link to comment Share on other sites More sharing options...

That's almost gotta be the master cylinder housing leaking. http://www.tpsgarage.com/TGP/brakes/powermaster.htm Prior's contact info can be found there if you want to call them for a rebuild quote.

mindgame Posted February 17, 2006 Author Report Share Posted February 17, 2006 actually, it looked like it was leaking from a few places. kind of hard to pinpoint exactly where everything under the resivoir was completly dirty. just went thru it and put new o-rings in it, put some dressing on the gasket it was still in good shape and couldnt find a new one anywhere. and make sure everything was nice and tight and seems to be fine so far. just the problem mentioned above.
