[1951 Buick Super56C pulls to the left when braking]

I had this same problem with my '55 Century.  It turns out it wasn't the brakes at all.  You mentioned that you had the front end rebuilt.  I also had the front end apart to replace the rear main seal on my car.  After this job the brakes pulled.

 

What the cause of the brakes pulling left and sometimes right was the adjustment on the steering cross shaft (to what the pitman arm attaches).  At the end of this shaft is a slotted "screw" that I had to adjust as per the manual.  The left side of the shaft on my car was way off, the right side was off a bit.  Turning this slotted screw in a couple of turns solved my brake pulling problem.  You may need to make the adjustment, drive the car for a bit, then maybe have to turn the screw in or out a 1/4 turn or so to fine tune it.  I would bet your car has the same issue as mine.  I don't know how many hours I spent working on the brakes when that wasn't the problem at all.  Hope this helps.

Hello all. I tryed to adjust the slotted screw that you said, but it is already fully in, are you talking about the "plug" in the center link that tigthens the Pitman arm connection?

 Another thing is the LF wheel tends to grab/lock sooner than RF wheel even at low speed, indicating a brakes problem, more than a steering problem

I had the same problem in my 1951 Super 56C. Muggy weld worked perfectly. Even put some reinforcement in the back. Can be replated if needed

Hello, I had the same problem.  I used Muggy Weld, and   reinforced the center with some additional steel, also using Muggy Weld, then I sent the parts to be rechromed. Good results

Hey there...I'm Aaron...

The seal kit should be the same between your Super and my Special. The seal from Fatsco will go into the torque tube flange around the prop shaft. The one that seals the splines does not come with the kit. I bought mine from Bob's Automobilia, and as mentioned in the article, made up the spring and washers from a used master cylinder rebuild kit (the 5 dollar variety). SP-132 Seal Kit Additionally, you might want to lube the rubber side of the torque ball retainer with some Vaseline or something. I used trans. fluid on mine, and on cold mornings, the first time out of the driveway, it makes a groaning sound as it articulates. It's fine after that.

Hello, Im Luis Garcia, new to this forum.I`m living in Madrid, Spain, and this makes looking for info more difficult.

My car is a 1951 model56C, and I have the problem of the splined shaft seal (Sp132 kit), that I cannot find where to buy it. Can I use the PS463 sold by Bob`s instead?

Could you, please give me some more info on how you did with the master cylinder kit? .Perhaps some photos or drawings?

Thank you
