'57 Front and Rear Brake, Backing Plates

[Bob A.]

What was the original finish on the 1957 Brake Backing Plates? Bare metal, plated, painted, etc. What would be a good process to use in restoring original, rusty plates? Thanks for your valuable information, it's greatly appreciated.

Regards,

Bob

Mike:

What was the original finish? If painted black, what sheen?

Thanks,

Re: '57 Front and Rear Brake, Backing Plates

Bob/Mike, An alternative to blasting that I like is to soak the backing plate (or any metal part) in a Phosphoric Acid solution. I use a 5 gallon pail. The Phosphoric Acid is available at most auto parts stores - the one I use is a PPG product. I like it because it distresses the metal less, is really pretty easy to do, and cleans the parts up just like brand new. It might be worth a try - just my 2 cents. By the way, after doing my chassis parts, I shoot them with Krylon satin black - it's a pretty good match. Steve

Re: Original finish?

Bob, My belief is that they were black (on my 56) - probably dip painted. Steve

Re: Brake Backing Plate, Finish/Sheen

If the Brake Backing Plate was originally black, what was the sheen?

Re: '57 Brake Backing Plate problem!

At the top of the rear Backing Plates there is a sub plate with two tabs (.5" wide x .25 thick, bent outward on a 45 degree angle) that straddle the ends of the wheel cylinder. One of these tabs are broken off on each of the rear Backing Plates. On the Right Rear Plate the Right tab is broken off, on the Left Rear Plate the Left tab is broken off. Nothing else is damaged and there are no signs of any wear on the Backing Plates.

Questions:

1. What could cause these tabs to be broken off? They are quite substantial!

2. What is the function of these tabs?

3. Is there any logical reason that these tabs would have been removed

intentionally?

I would like to fabricate two tabs and have them welded on.

3. Does this seem like a reasonable approach?

Thanks,

Bob Adams
