Hey everyone I'm new to the forum here so bear with me,
This all started about a week ago, when I notice the pedal went halfway before it got stiff and stopped the car. So I adjusted the back brakes, no change happend. Then when we adjusted the left front tire, this is when the pedal suddenly went all the way to the floor.
A friend and I have also jacked up the bug, took every tire off, then all the drums off to see if there were any leaks in all four wheel cylinders and there are none. We adjusted the brakes again while every thing was apart but there was still no change in pedal. We also tried adjusting the master cylinder push rod and still nothing happend. We have bleeded all the brakes almost 15-20 times to no change in pedal, every time there has been alot of air bubbles, we have kept the brake fluid in the container and bleed the brakes by sticking a hose on the outlet and the other end of the hose in a cup of brake fluid.
Now to the master cylinder, I bought a new one for mid America motorworks and replaced the one I had in before, absoluty no change in pedal. Now there still is pressure in the line, when bleeding it it comes out like crazy. But after were all done and even before the pedal still goes all the way to the floor. It actually still works, barely, when the brake is all the way to the floor we can't turn the drum by hand, but we can not test it for a 30-60mph rolling 2ton piece of metal.
WHAT IS THE PROBLEM?
We have spent over 2 days trying to figure out this problem to no effect. We have considered that both the old and even the new master cylinder plungers or something might be dead, but we don't know how to test it. All we know is that something is sucking major amounts of air into the system, up to ten or more bubbles for each wheel. If you need any other info please ask, it is a 1965 Baja Bug with a 1600cc engine.
Any input or info or advice is greatly appreciated
