  Im looking to change from hydrvac to a new booster M/C for drum brakes. Does anyone make one for a 57, like a conversion kit.

I faced this problem a couple of years ago and wanted to have a dual master cylinder but could not find a conversion so I had the Hydravac and master cylinder rebuilt.

I rebuilt my Bendix Treadlevac and booster too. It was cheaper than going down the conversion road although I did do the work myself. I have attached a couple of photos showing the before and after.

  Ya I did the same thing and added new wheel cyls and hoses, and still no brakes, Im sure some of you remember this thread from last year. I dont know what to do so I was thinking of using a different booster, I just dont know which one to go with. Most boosters NEW,, use disc brakes for front. I dont want to do that

Booster Dewey's reputation is such that he is a  "go to" source for these repairs, from what I understand.

That said, the guy I used and was more than satisfied with in terms of communication, quality of work, turn around time and price was -

I recommend him without hesitation or reservation.

    Thanks guys, maybe I didnt make myself clear. I have a rebuillt booster hydrovac, M/C and wheel cyls. all installed but I still have NO BRAKES. So I was thinking of going to a New booster with master that will fit 4 wheel drum brakes. For a 1957 cadillac. What you guys are showing me is places I can get my stuff rebuilt. But thanks

Have you tried hooking the hydraulic line from the master directly to the brake line distributor on the frame, bypassing the booster?  I can't understand how there are no brakes at all.

Have you taken it to a mechanic?

No brakes?  My first thought is corrosion in the brake lines preventing brake fluid movement?  We all forget the every time we use our brakes we are bringing a small amount of the atmosphere into the system and after a while it can accumulate and rust enough to block the lines. Bigger problem in humid areas of course, but all atmosphere has some H2-O in it.  I once had a Triumph Stag and the wheel cylinders are installed at a tilted angle. Needed regular bleeding and still rusted in the low section of the wheel cylinder.  Parking on an incline regularly could also cause this problem.

I have used Midwest Power Products with good success.  They have about anything for brakes.

Put your foot on the brake pedal.  Start the car.  Does the pedal drop a little or stay stiff?  If it does not drop, your booster is potentially bad.  I just went through this on my 56 using an aftermarket corvette style dual MC and booster.  Ended up that the hard vacuum line off the intake manifold for the booster was clogged with mud daubers!

Outside of that, make sure you bleed them all really, really well.  Make sure your shoes are adjusted outward enough so the wheel just scrubs a little when you rotate it (jacked up).

If you are not getting good fluid movement when you bleed the brakes, your MC might be defective or need adjustment.

   Funny you should say that about the pedal. When I tryed that holding the pedal down and starting the car, the pedal actually rose about 1/2 in.  Weird right? Why would it do that.

Again and again--the 1957 system is identical to 1955 and earlier.  It has NOTHING IN COMMON with 1956 or 1958 as those systems were treble vacs.

Yeah thats weird for sure.  Get out there with a buddy and bleed the hell out of them (car off, doesnt need to be running).  You know, start passenger rear, driver rear, passenger front, driver front.  Leave cap off MC and make sure it never runs out of fluid. 

Now I'm not familiar with the 57 setup, but, assuming its the same situation as most, did you bench bleed the MC prior to installation?  It sure seems like theres an air bubble in there somewhere.

If THAT doesnt solve it, I believe your booster/MC is suspect.

edit: get under there with a good flashlight and inspect every brake line joint.  Junction blocks, hoses, wheel cylinders.  Make sure theyre bone dry.

       Rob thanks for advice, ya I did bench bleed M/C and booster, all is newly rebuilt. I think ur right about bleeding the  out of the lines. Still cold here in Canada so I will wait a bit. If all fails, I just found at Caddy daddy a new booster with M/C for a 1957 with 4 wheel drums for 900.00, I will try that if all else fails. Anyone ever do business with these guys?

Is the MC part on the 57 like the treadlevac ones?   Can you separate it from the booster section and manually actuate it to at least find out if are able to build pressure in the system?   Just thinking if that is possible that may help isolate if the issue is in the MC section or some combination of the booster and MC.
