I think my hard pedal,no stop was due to some of the chinese fittings I plumed the system with. Repaired a couple of leaks and re-bled the system, should be ok. As far as milling the cross shafts on my a-arms, it might not be necessary with the torino spindle swap. Ford calls for 1 and1/2 degrees positive camber, we were shooting for 1/2 degree negative.





thanks, Mark

Old car mark, glad I found your post. I am finishing up a 58 ranchero 292 for its maiden voyage, I have a similar problem. I am using a dual master with a 7" booster, I bought the setup from gearheads several years ago (bad experience), when the time came to install it the booster was broken where the rod comes out. Rather than try to deal with these people,I bought a replacement from speedway motors. I'm running Torino disc brakes on the front, stock drums on the rear, all parts new. I have the same feel, pedal is rock hard, no power assist feel. I'm moving the car around and I'm afraid I'm going to go through the shop wall.I also have an adjustable proportioning valve. I'll check the things mentioned in this topic and hopefully find the gremlin. By the way, the torino spindles are a good disc option for the 57,58 cars, I did have to mill 3/8" off the upper a arm cross shaft to get my camber back. Same spindles on LTD 2's, montegos, ect.

thanks, Mark

Mark........I'm pretty sure the Merc wheels are 5 on 5,where your Ford is 5 on 4.5.

Is mercury bolt pattern the same as my Fairlane?Anyone know?

  

Thank you for the reply. I want to put the duel master cylinder on a 55 Fairlane. I will look for a 67 Falcon master cylinder and give it a try. Thanks to all.

You didn't mention what body you're running but I'll tell you that I used a '67 Falcon drum brake dual reservor master cylinder on my '57. Bolts up to the two lower holes on the firewall. (Put bolts in the upper two now empty holes). I used the original pushrod and relocated the stoplight switch to the now unused opening on the original brass tee fitting on the frame rail. Both reservors are the same size, looks good and works great. The line for the front brakes goes to the rear reservor.  hope this helps.

FIGHT CONFORMITY! 

You know, I considered adding disc brakes but haven't seen a kit that maintains the 5 on 5 bolt pattern. Most are 5 on 4.5 . Guess I'm just being picky

Glad to hear it works.Now its time to add disc brakes to the front!LOL

  

Got it straightened out.

My vacuum line was pinched and the push rod was out of adjustment (to short) . Adjusted that , fixed the hose and I have power brakes. Mind you it doesn't stop like my 2006 pick up but for 2 tons plus with drum brakes it's ok.

I measured 20" of idle vacuum from my vacuum source at the 1/2" nipple located at the base of the carb and it seems to do the trick just fine. Thanks for all of your input.

hi with the engine not running pump the brakes to exhaust all assist hold pressure on the brake peddal and start the engine if the peddal doesn,t drop you have no vaccum assist then you can try to find out if its lack of vaccum or the booster   shakey Pete
