FRUSTERATED!!!!!!

If anyone has an idea how I can fix my stupid brakes....I'm all ears.....Here is my problem....I replaced my master cylinder (we have no clue what the MC came from) with a MC from a 1970 truck....Apparently my pushrod was too long for this MC and I blew the seals out of 2 new MCs.....I want to have my car out there sat but dont know what to do about this issue....any input on what others are running for MCs and pushrod length is greatly appreciated.....

I know the simple thing to do is put in a racing MC but the rules dont allow the racing MC in the hobbys...

Good luck Dosh. Hope you're out there this weekend. Brakes are over rated anyways. lol

Yeah....I keep hearing that...but I have met walls before and would like to not do it again.....lol....

DOSH, ARE YOU RUNNING WITH THE BOOSTER? HERE IS WHAT I HAD, I TOOK A MASTER OFF A 68 3/4 TON GMC AND MOUNTED IT TO THE FIRE WALL AND WHEN I MOUNTED IT I HAD A 1/4 IN. END PLAY IN THE PEDAL WITH BRAKE ADJUSTED UP AND THEN BLEED OUT, THEN BACK REAR OFF. HOPE THIS HELPS.......

I'VE BUILT 30 -40 OF THOSE METRIC CARS AND ALWAYS REMOVED THE POWER BOOSTER AND MADE AN ADAPTER PLATE AT LEAST AN EIGHTH OF AN INCH THICK WITH 6 HOLES IN IT FOUR OF THE HOLES AT THE TOP AND BOTTOM WERE THE ORIGINAL HOLES FOR THE BOOSTER CENTER THE OTHER TWO HOLES BETWEEN THE FOUR 3/8 DIA. HOLES AND ADD ABOUT AN INCH AND A HALF FOR THE MASTER CYL. THIS WILL KEEP THE PUSH ROD IN LINE WITH THE PEDAL. I ALWAYS USED A MANUAL, NON POWER MASTER CYL. FROM A '73' NOVA ? CHECK AT YOUR FAVORITE PARTS STORE. YOU SHOULD BE ABLE TO USE YOUR STOCK PUSH ROD WITH OUT MODIFICATION, BUT IF NOT I THINK YOU KNOW WHAT TO DO. I'VE NEVER BLOWN A MASTER CYL. BUT I HAD THE ROD ADJUSTED TOO LONG TWICE ON TWO DIFFERENT CARS. THE PRESSURE ON THE BRAKES BECAME GREATER AS THE RACE WENT ALONG AND THINGS HEATED UP CAUSING THE CAR TO SLOW DOWN .THIS IS NOT GOOD. HOPE I WAS ABLE TO HELP GOOD LUCK . JOANINTR

No brake booster.....and none of the dang parts stores seem to carry anything that old...anyone got something laying around?lol

We would ditch the booster and make a plate to support the firewall from moving. We used a master cylinder off a 68 chevelle. The rod should be fine Just make sure that when the pedal is released the rod is loose from the back of the master cylinder (no pressure against it) if it needs it grind it shorter. Also make sure the pedal has some type of stop to keep from pulling the rod out of the MC.

Any master cylinder will work. some are just hard to push. Run what you have then find a better one.

Put a grinder on that rod or adjust the pedal stop. Just make sure the rod completely releases and does not come out if you pull up on the pedal.

And yes I do have some laying around that you can have!

Mike....PM or email me (tomacdriver12@yahoo.com) and let me know about the MC...I am off tomorrow (Thursday)

My cell number is 386 937 3554. I am at the shop every thursday from approx 5 til 8 for Racing Thru The scriptures. I will try to swing by there this morning and put them in the truck.

Yall are all welcome to come to the bible study, which is actually 6;30-7;30 the rest of the time we have food, talk racing or work on cars, watch our race videos, shoot pool. We have even scaled cars that some have brought.

Give me a holler

Just thought I would say...I HAVE BRAKES NOW ...now i just need my power steering fixed...lol...got new pump and the rear seal was leaking so I am waiting for them to send me a new one.

Thanks everyone for your input
