[Chevelle-list] No Pedal - Poor Braking

[Randy S Johnson]

This may sound really dumb, but this happened to me this year.  I went 
from a manual 4 drum system to a power disk braking system.  I got 
everything all hooked up, but I wasn't impressed with the stopping power. 
I started to hear a leak from my booster after a few months, so I ordered 
a new one.  Well I removed the master cylinder and realized my friend who 
hooked up the booster and master didn't put in the connecting rod between 
then.  So I had a huge air leak through that area and I had no physical 
connection between the booster and the master.  I doubt anyone else in the 
world could be that dumb, but I like to share my dumb stories.  PS~I drove 
my car like that for 5 months before I fixed the problem.  Now the car 
actually stops.  Good luck.  I'd guess it is a bleeding issue.  I also had 
a problem while bleeding that one fitting wasn't real tight on the rear T 
and it kept letting air slowing back into the system while bleeding.

Keep bleeding, bleeding, bleding then bleed some more until you have more 
pedal. That has been my experience at least.

Picked up my 70 Chevelle from the body shop on Thursday and took it for 
its maiden voyage this weekend. Car looks and runs great but won't stop. I 
have absolutely NO pedal. Its not spongy but way to much pedal travel. 
Hopefully someone out there can guide me to a solution. Here is what i am 
running...

4 Wheel Drum Brakes - All pads and hardware are brand new
4 New Brake Cylinders
New Drum Brake Master Cylinder
Used GM Power Booster
Original Proportioning Valve
All New Lines
Silicone Brake Fluid

I adjusted all of the brakes but it did not help. Bled them again but did 
not find any air in the lines. Wondering if I should ditch the booster and 
put the master cylinder back on the firewall as it was before. It is the 
only thing that I changed in the setup.

Any help would be greatly appreciated. Now that I have it done I want to 
drive!
 
Thanks, Dan
