Earlier single GM master cylinders use a big snap ring to hold a plate in the back end of the cylinder and trap the flanged rod. I don't know how Mopar, etc. do it, but some positive retention of the pushrod is clearly essential.

Wow, tough to believe that this pushrod could come out of the master cyl. on braking system, and that this safety problem hadn't been adressed years ago---either by the automotive industry, or the governing bodies of drag racing. It would seem a easy fix..... WJ

I put a little chain from brake pedal to fire wall to keep pedal from traveling to far back and allowing the rod to come out. The pedal is not allowed any more movement than is needed. In other words, If I "pull" back on pedal, the chain grabs it and stops any backward movement. Hope I explained that right.

If the clip that holds rod in master was to fail for whatever reason, the way I have the pedal limited to movement should (will) keep the rod from coming out of master. This is on my '69 Mustang.

Ken, Glad you are here to talk about it.

Ken,
First of all, I'm glad you 're doing okay. I'm looking forward to see you racing again one day.

On the brake deal , on those old 66 Chevies I used to race , the manual m/c had a deep recess in them and a 3/8ths push rod going into it, and nothing else. I would always replace the brake pedal up stop rubber bumper with a 3/8ths bolt and double nut deal to keep the pedal from traveling too far.
On my 62 Tempest I'm putting together, I've got a flanged rod in the m/c , plus a split U shaped washer deal I made that's retained by the snap ring, plus a solid up- stop for the pedal, and also a 2" long rubber cup over all of it, as a 3rd backup .
I agree , it's way past time to stick your head up under that dash and see what you've got and how you could improve it.
Do it tonight!

Now that is funny, Mark.....it's probably really hurting Ken to smile as he reads this, but I'm sure he is....... WJ

It's not Ken I'm worried about . I'm sure he knows what to do on his next car!

I don't know Ken Etter but have to say Ken you are a very lucky man and I am glad your ok.

I don't race a Stocker these days but do have a dragster.......The first thing I did when I bought the car was add a completely seperate brake system. I have two independent sets so if one failed the other is there.

NHRA made numerous cars with this setup disable the hand operated M/C at some races earlier this year........Although this is not a Stocker I am bringing it up to point out how shortsighted NHRA is on safety related items sometimes......

I have read about at least 3 Stockers that have had the brake rod fall out and all 3 cars were totally destroyed. The drivers were all lucky to survive these accidents.....

NHRA needs to pay more attention to this issue and with all the terible crashes due to loss of brakes or stopping ability........they don't need to disable someones backup system because they think they are using it to hit the brakes to hard at the finishline.......That is a nonsense reason to someone like myself who has this option striclty for safety......

Everyone needs to check this issue on their cars.......I have to admit I never gave it much thought before I saw the results in pictures over the last few years....Peter Biondo.....Woodro Josey and now Ken Etter.....

Rich a friend said we were maybe gonna be able to put the handbrakes back in our dragsters in 2011 i'm like u what in the hell is wrong with a backup system, seems like NHRA would use some common sense on this issue

Their is alot of positives comeing from this thread.If you go onto strange's site you will see the master cylinder uses a rubber o-ring type grommet at the end of the rod where it enters the master to hold in place.Their is also a boot to keep dust from inside the car from entering the bore and to also help keep the rod in.I agree with Mark about taking the rubber return block off and installing a double nutted 3/8 bolt as a more positive return stop.I would imagine many of these rubber stops are cracked or missing anyways.The next thing would be a bracket coming off the firewall from the inside where the master bolts too and make some sort of a hoop similar to a driveshaft hoop to further support the rod.A brace or plate on the outside of the firewall to limit deflection would be another good idea.Just some thoughts.
