soft brakes - why? - Page 2

I will try that before pulling everything apart. I called Wilwood, and they said outside should do it... but she really did not sound real positive.

Easier to start there than to start at the MC!

Thanks again everyone!

Put a couple of Viagra in the master cylinder. That should stiffen it up some. HA HA HA HA HA HA HA HA .

I had a similar problem and bled all bleeder screws on the calipers and that solved the problem.

Thanks Jim and Mark. Will do this as soon as I get a chance. Wife was not much help today...

Mark, hope you are doing well. See if you can keep Chip in line.

Chip, do you have a lot of experience with Viagra? Is that what the "Legend" is all about???

Ken,
Don't use it. At my age I value my sleep too much. LOL

Yeah kinda like that cialis everyday commercial......and they really expect me to get anywork done like that ? I mean seriously.......

Sleep is a good thing......sometimes very underrated.

I have to agree. Amazing how much quicker I can get caught up on something that 10 years ago I never thought I would get enough of!

Maybe that is why she would not help me with the brakes today?

A second alternative is the vacuum bleeding kit. This kit works in the opposite manner of the pressure bleeder, applying a vacuum to the brake system in order to draw brake fluid out of the car. The system works well, but can sometimes cause air bubbles to form in the lines. Particularly on cars with rear brake proportioning valves like the Porsche 914, the vacuum system can leave air trapped in these valves, giving a spongy pedal as a result. When using the vacuum bleeding system, the best approach is to bleed each corner of the car several times, in order assure that all the air is out of the system. Simply fill up your brake reservoir, attach the pump system, pump up some vacuum, and then open the bleed nipple. Brake fluid should be pulled out of the system when the vacuum is applied. If it’s not – you may have a problem with your brake lines.

A way I heard of but never tried... You can do it by yourself. It may take a lot of fluid. 4 hoses to fit over the bleeders (or 8 reading the previous post), open all bleeders, drop the hoses in jars or containers at each wheel. Put about a couple of inches fluid in each container. Make sure the hose ends are submerged. Start pumping the pedal, keep filling the MC and pump the pedal until the air goes out and fluid gets sucked in. Keep pumping and filling the MC. If there was a lot of air you will see bubbles but I think almost all of it is out now with a little trapped somewhere. So when you think you have pushed the air out or flushed the fluid well, tighten the bleeders and remove the hoses. Top off the MC and see what you have. A defective MC comes to mind too.
