Do you mean the rubber grommet that the steel line pushs into |

|
|
I have a 69 bug and it has pretty much been sitting for 2 years now. The brakes did work alright and then 2 days ago I added Brake Fluid to the DRY reservoir and now they don't work at all. Does anyone have any suggestions?
Thanks in advance,
Jason |

You probably have a leak someplace. If it lost the fluid while sitting.
Start by bleeding the brakes.
You are dual circuit, so start at the right front, and then the left front.
Right rear then the left rear.
You may have to go around several times before you get all the air out.
Then check for fluid leaks after you get pressure.
Dont drive the car until you find where that fluid went. _________________ Society is like stew. If you don't keep it stirred up, you end up with a lot of scum on the top!--Edward Abbey

Had the same problem and I found that my master was leaking and the fluid was accumulating on the driver side floor! A real mess and a lot of wasted brake fluid. Good luck! _________________ '67

Successfully finished bleeding the brakes on my 67 vert today and am good to go. Tried it about two weeks back when my daughter was here, we did this as a two person team but were not successful at that time. The pedal was still soft and we ran out of time for the weekend.
Today, I adjusted the brakes out to just dragging and went through the procedure as described, right rear, left rear, right front and left front. I did note that most of the air, actually a substantial amount was bled out of the front passenger side. My thoughts/observation is that this has the most rise of all of the brake lines and, I believe that with letting the car set for two weeks, that it was the most likely place for the remaining air to collect and as such, was easily discharged once we (daughter and I) went at bleeding the brakes again.
I'm not suggesting letting a car sit for two weeks between attempts, but it did cross my mind that by letting the car "set", even for say overnight, that residual air in the lines would rise to and accumulate to this high section and as such may give us a leg up on successful bleeding of the system. This may actually be true for each one of the lines as all of the air came right out on each of the legs. Took us about 50 minutes (we had to flag down the ice cream truck and took a break, hot here in Southern California today). Just a thought, I am good to go, will fire it up tomorrow and road test. _________________ Charlie

Finally have brakes on my '67. It turns out that the rubber? flex lines in the back had collapsed. My recommendation is spend the little extra $ and replace them about every 2 years. _________________ '67

Posted: Sun Jun 22, 2008 7:01 pm Post subject: 67 brake bleeding questions.. |
|
|
1st. In reading one of the previous posts, someone was having problems bleeding his brakes. Someone else asked if he was dealing with a single or a dual system, and that there was a different way of bleeding a dual system. What might the difference be? 2nd. Has anyone else ever had a situation where they were getting fluid to all but one brake location (drivers side rear). All other wheels will bleed fine. I can't seem to get fluid to this wheel.. Any hints? |
