I'm almost 100% sure it's bubbles.

- No assumptions allowed. That sound can easily be made by the forceful return of the fluid to the reservoir.

Find someone you don't consider to be worthless and have them work the pedal or study the reservoir as you work the pedal.

I'm sure it's making bubbles judging by the fact that I can see bubbles rising through the brake fluid

- NEp8ntballer you started this thread asking for advice. I've invested time, checked back regularly, and given thorough, respectful advice on a logical approach to helping you solve this very solvable problem.

You surprised me when you said you were "almost 100% sure it's bubbles". When I'm troubleshooting, this equates to not sure. Being sure is important in deciding the next troubleshooting step.

Today you are not only sure it's bubbles, but you join your boy in smartass commentary directed at me and Hawkey18. You have found the end of my patience.

Good luck with your problem.

QFT. Fix your own brakes. Is it something in the NE water that turns everybody from there into ********?

His "boy" has been working on the car with him. His boy isn't your average 'shade tree mechanic'. His boy is tad smarter than your average are-tard.

We've told you countless times that it is NOT a leak. IT IS NOT A LEAK. Chris and I have bled the crap out of those lines and passed well over a quart of fluid through them (damn near a quart through trying to troubleshoot ONE line). It appears that when the brake is released, air is leaking by the seal into the MC. When bleeding the brakes, the bubbles appear in a rhythmic pattern and consistantly so.


Jason hawkeye18 can hang with the crowd here, so I'm pretty sure he's not offended.

With that said, I will be borrowing an ABS bleeding tool and running it through that step, however, I have let my SHO sit for MONTHS without any calipers connected or anything else connected (draining) and my brakes worked just fine with a simple bleed.

and I appreciate your help but it would be unscientific of me to be 100% sure of most everything. before I made that post I had my sister work the brake for me again while I had her move the brake the through the first inch of travel. I'm not too sure what turbulence looks like but I know what rising bubbles look like. so if the two do not appear identical then I'm confident that I'm seeing bubbles.

another thing that supports the idea that I am seeing and hearing bubbles is that when the sound and sight happens the pedal is soft and is not exerting a lot of force against my foot to relieve the pressure.

We've told you countless times that it is NOT a leak. IT IS NOT A LEAK. . . .

- It never occurred to me for a moment that you are 'average' in any regard, and I've seen no reason to doubt your opinion of your intellect relative to an 'are-tard'.

As far as the LEAK goes, I believe you. I indicated as much in post #8 and again in post #13, and haven't said differently since.

Looking back, you offered this assessment in post #10
"I'm willing to bet the MC is introducing the air."​

But never supported your assertion by answering this question;
" . . . can you describe a process by which the MC can continue to introduce air into the system without an open, and without running the reservoir out? I can't envision one."​

No matter, My SHO brakes are just fine, and I've come to the end of my patience for your nonsense as well.

I'll answer how when I can type a response at a computer and not an iPhone.

while I will agree with you that everything i've read is telling me that there is air in the system, logic tells me that if I am pushing new fluid out of all four corners that I should also have a lot of the air out as well.

I am having the exact same problem. I installed the ss lines and new rear calipers and I too have been bleeding the shit out of my brakes for hours without getting a firm pedal and actually my pedal is so soft I don't feel safe driving the car.

I see a few responses about the MC introducing air into the system but if my MC was fine before I installled the ss line then why would my MC all of a sudden go bad.

From what chris has told me before, the car didn't brake well before he started and there were too many variables to start with before troublshooting down to the exact problem. The car has had a bit of a rough life and we are working our way down the line. I do know from the night I helped him that the MC and reservoir make a lot of clicking and girggling noises.

We have bled over a quart of fluid through the system. If you feel inclined Chris, loosen the lines on both ends of each SS line and re-tighten. I will have an ABS tool tomorrow and will bring it down to run on your car. I want to flush my system soon too so it will come in handy for me too.

My car hasn't stopped well since I bought it in 2003. I tried everything from performance rotors and pads to Motorcraft rotors and pads and nothing ever worked. So now I spend close to $700 dollars buying Hawk pads and centric rotors, doing the 11.6 upgrade in the front and REAR and new rear calipers and ss lines and it's worse now than ever. As I kept bleeding and bleeding over again I had a feeling my MC was bad but I was so frustrated and stupid I was bleeding for a good four hours.
