Hi all:

In the early 90's I took my '66 300 to the Seattle area for a car show. On the way, somewhere in southern Oregon, I decided I did not have a firm enough pedal. So I unbolted the M/C and lengthened the pushrod a tad. Everythins seemed to work fine but it was not really put to the test as I was on Route 5 and no need for brakes. Going across the bridge at Portland to Washington, at 60 mph, I found out I had no brakes. I carefully used the gear shift and hand brake to slow down and get off at the next exit. Upon removing the M/C cap, I found the fluid level was much higher than when I last observed it. I readjusted the pushrod back to where it was before and suddenly I had pedal. SOOO! I learned never to touch the pushrod.

I was really lucky. If I had had a bad accident when the brakes failed, I would probably endangered my parents who were travelling with me.

Larry,
One of the lessons I have learned is with that pushrod which goes from the booster into the mc. The shop manual for my H says to not adjust it. Chip Chapman years ago sent me a tool (a gage) for setting it which I have lost.

I set mine leaving .050 clearance although it is a trick to measure clearance. It has a huge effect on pedal height because of the lever arm ratio of the distance from that rod to the pedal pivot compared to the distance from the pivot to the pedal. If youset too small a clearance, when the fluid expands from heat, it will set the brakes.

Always learning......like the idea of adjusting the drums tight to the shoes to eliminate the possibility of adjustment being part of the problem while trying to get a pedal. Also am learning to cap off either the front or rear brakes temporarily with brass from NAPA so as to rule out 50% at a time of air leaks when all cylinders and hoses have been replaced. Most replacement master cylinders instruction sheet tell to bench bleed the master before putting on the car but like the plan for a brake line being bent to take and give from and to the master. About the time I finally learn all the tricks, it will be good to use on the chariot wheels on the streets of gold. When I was a Shell dealer in the middle 60's, my first brake job was a 57 Plymouth. It took more then two days to get a brake pedal even with the help of the parts su pplier and the mobil brake drum and shoes jobber helping. End of the second day I left the car on the hoist and over-night the air found its way to the m/c and all was good again.
