Hi Doug,

I didn't have a problem with removing the rod from the booster, however, I suggest you disconnect and remove the brake light switch first,?if yours is old and you don't have a spare, just in case... You will have to adjust the switch after you install the new rod, anyway, and if the battery is connected, the brake lights will come on when you remove the switch. I removed the wire from the switch while I had the rod out. The rod pulls out of the booster easily. You don't have to remove or loosen?the booster or disconnect any fluid lines, this job is done entirely under the dash. One other suggestion: make the rod a little longer than you think you need, and then test-fit it. If it's too long (you won't be able to insert the bolt into the pedal arm)?you can grind it down on your bench grinder. Don't forget to allow for the brake light switch, too. The end of the rod is parabolic, kinda like an acorn nut. Let me know how it works for you!

Regards,
Mark

Hi Mark,

?

Thank you for your reply! Your solution to the problem sounds like it will work on my H as well. It's the onle explanation that makes sense to me.

?

I think that I have an original booster on my car, but after 46 years, who knows.

?

Did you encounter any problems with removing and replacing?the push rod from the booster?

?

Thanks again,

Doug Warrener

Hi Doug,
I had the same problem with my H. My pedal traveled almost to the floor so I felt really uncomfortable driving the car. I tried adjusting the rod, and the brakes locked up until I returned the adjustment to the original position. I? finally found the solution. I removed the push rod that connects to the brake pedal and protrudes into the booster. I took it to work and had our tool maker duplicate one that was about? 3/16 inch longer than the original one. Now the brakes work fine. Turns out I have the wrong booster on the car.

Hi Group,




I need some expert help in understanding a problem with the "push rods" in the 


power brake booster on my 300H.


I obtained this H about two years ago, and the brake pedal has always had about 


3/4 inch of free play. 


After completely going through the entire system ( drums, shoes.wheel and master 


cylinders, bleeding and replacing the fluid and adjustments), I have finally 


determined that the problem is inside the power brake booster.


The push rod that engages the master cylinder piston was adjusted properly and I 


determined that the pedal free play was between the two push rods somewhere 


inside the booster.


I then adjusted out the push rod to the master cylinder piston until most of the 


free play was eliminated.


As you can guess the brakes locked up, and I have now re-adjusted the push rod 


to it's original position and again have the free play in the petal.




Thanks in advance for your help and comments,


Doug Warrener
