Campeck,

Were you using the Motive Power bleeder to bleed your brakes? On newer Porsches (e.g., 996s) you can use up to 15-18 psi. On the older Porsches, you really should not use much more than 10 psi or you will start to blow out seals. How much pressure were you using? Did you put any air bubbles in your system? Can you see where it is leaking?

Glen,

I don't think this is (exclusively) and issue of air in his brake system. In his first post in this thread Campeck stated that the MC leaked when they pressurized it with the brake bleeder. If the MC leaks under that pressure then it will surely leak under actual use and exhibit bad/dangerous braking characteristics.


Campeck,

I'm not trying to bust your chops. If you want to drive your car like that on closed roads with no other traffic, then feel free. However, when you put other people at risk by driving a potentially dangerous car on public road, well then I have to take issue.

I doubt the back is going to come down enough and with 300# upfront it is going to understeer like mad. As for the BJ/A-Arm about 13" from center cap to fender opening is a decent ratio.

manning..it IS something to roll my eyes at it. why? cause you cant read/listen.
no offense..really. but where did i EVER lead you to believe that my pedal goes to the floor....really spongy? nowhere. isaid it was like bad NA brakes then..pump....good turbo brakes.

Campeck

why delete the torsion bars?

because they would be obsolete if i put 500# springs on. they would be dead weight and just a pain to keep around.

Yabo

ashton.. the whole point is stupid. if the brakes aren't functioning right.... the car should not be driven, period. You don't know that the master won't blow at any point, the problem get worse, etc when it's not working correctly. Brake system uses very little fluid and uses a high pressure on a small amount of fluid to actuate the calipers..... if there is a small leak.. it porportionaly has a huge affect. Get AAA, it's cheaper then a new car when something goes wrong.

Manning

Your first post actually. Granted I assumed the "to the floor" part, but where you stated:

...it is pretty easy to assume that is what was happening. The MC started to go on my Scirocco many years ago. No sign of leaks whatsoever before hand. Then driving home one night I almost stuffed it into the back of another car. I had to pump the brakes just like you describe to get the car to stop. Had to do that all the way home, about a 20 mile drive. I wouldn't drive that car again until after I replaced the MC.

And yeah, what Devon said.

In a nutshell - if you can't deal with criticism, don't post stupid sh*t.

Geo

A bit harsh, but totally to the point. Something I've been known for.

There certainly is wisdom in this that folks should take to heart.

Nobody is saying don't share. But if you do something foolish and share it, don't get mad if people call you on it and in a very direct fashion or worse. And this is directed to everyone - certainly not singling out Campeck (and certainly not excluding myself).

with 300 lb springs in the front, a good helpful upgrade would be a 968 rear M030 sway bar on stiffest setting to reduce the understeer somewhat. 80lbs springs on 968 M030 rear Koni shocks would also help this too. I'm not familiar with this setup on a 300 lbs front car, but I've seen it on a 275 lb car and it was pretty stable.

Campeck

stig. i have a 19 mm rear sway with serges droplinks. and its set pretty stiff. i doubt toying with it will help any. its a combo of the stiff front and skinny front tires. 205 front vs. 225 rear.

tifosiman

No offense intended Stig, but that sway is not going to help enough to make a difference. The only way to bring things back into the norm is to increase the rear spring rate. BTDT

Agreed. I have been known for telling things like it is and sometimes that is perceived as being rude, in fact a few weeks back I took a rather bad tonguelashing from 2 'Listers (who are now on my ignore list) for doing just that. When people post stupid shat, or step out of line, I just call it like it is, no harm intended or dislike imparted. (obligatory smiley to make things nicer for the understanding impaired)

Campeck, I know you mean well, and don't take anything said to you in this thread as being an insult. If people here didn't like you they would just have you on "ignore" and wouldn't be interested in what you are doing. I wish I was doing the projects with my dad that you are doing now, when I was your age. What you and your dad are doing together is great. Keep up the good work, and be safe.

Geo

Amen to that Tifo! Shoot, I wish I was doing anything with my dad today, but sadly he's been gone for 18 years. Kind of hard to beleive.

Campeck, you truly have something to be thankful for today.
