Does anyone know of a place where I can get my 4 piston Bendix calipers rebuilt or restored besides the Ram Man?
This is for a high end 69 b body restoration where functionality and originality are very important.

Brake and Equipment Warehouse in Minneapolis is the best for caliper and master cylinder rebuilding.

They will likely have to be sleeved and Corvettes typically have to be sleeved also. There should be a few Corvette re-builders.

I have an nos seal kit if doing a true oem restoration... Excellent condition dated 8/69

If originator of thread isn't interested in this, I am... I would PM you QuickBpBp, but apparently your message inbox is max'd out...

I'm pretty sure Rock Auto sells kits.

I just bought three sets from rock auto.

Thanks Troy for buying the NOS set pictured. If the OP is looking for Real parts for his restoration. I have another set available...

I never got a clear answer to my question on shelf life of seals when I worked at Raybestos, (I was once told 5 years), and I have myself used several decade old NOS seals when restoring some master cylinders. But all in all I'd feel more comfortable using recently manufactured seals rebuilding a hydraulic component, than 50 year old ones!

I'll buy the other set QuickBpBp, need some for my 67 GTX

I agree.

Not an item you want to blow out on you, LOL.

Thanks for the NOS set, they are nice. BTW, I don't see any reason that they shouldn't work just fine, everything looks new and supple. Matter of fact I'd have less faith in new Chinese made seals than 50 YO American made seals. .02

Your welcome Scott. I agree with your assessment also.

read and decide.
Wheaver contemporary parts are manufactured, make sure they are sold by a reputable name brand company. Their liability exposure plays a big role in the quality.
fwiw, I would not recommend using 50 year old brake parts, unless perhaps they were stored in optimal conditions.
Rubber parts in particular contain silicone that tends to oxidize over time..
Shelf life is noted in this link:

I'll agree that rubber products can break down over time (tires come to mind). My comments about not trusting modern replacement rubber parts possibly being less than reliable are partially founded on this. Brand new suspension grease boots, zero miles, no grease added yet, just loosely assembled to make the car rollable and sitting on a lift in climate controlled storage for a few years and this happened. Very reputable American company, Asian manufacturer.

sure looks like bad material, or, old parts. Silicone loss kills rubber parts. Notice how fast modern wiper blades fail. Manufacturers realize the importance of silicone (and carbon black) and can reduce the amount used in parts as a means to introduce design lifespan (or obsolescence). Coating, or storing rubber parts away from ozone (O3) that is an aggressive oxidant. Liquid silicone is pretty good used as a dressing to preserve or restore old rubber parts. Any petroleum based lube, or even silicone brake fluid is perfect to restore/preserve rubber parts.
edit: p.s. why the down side up on the castle nut?

looks like how modern [within the last 10yrs or so] MOOG seals get with very little use.
as the car has sat for a couple of years, it just took longer to split.

Srt, nuts were just tossed on to get the car rolling, no intent there. Its all been apart and correctly assembled with new boots since.
