is there any reason to not....

Put a sleeve in a pitted brake caliper. I have a box of calipers with pitted bores.
Thinking about sleeving them thus bringing new life to an old part.

Why not simply bore over and fit with new piston?

 

[bluerooster]

hadn't thought of that. Either way it will get bored. Are there oversized pistons available?

Make them, you'll know how big they need to be.

Early disk brake Corvette calipers had pitting problems and the fix was to sleeve them. I bet by now almost all of them have been sleeved.

I have not heard of it done on airplanes but I am no expert on airplane brakes.

Define early?

 

[Plano Pilot]

If I remember right 1965 was the first year disk brakes were an option and they became standard in 1966. Between the early 80's and early 90's I owned/restored a 64, 66, 69, and 76. The 64 was the only one that had drum brakes.

"Stainless Steel Brakes Corporation (SSBC) first pioneered the stainless steel sleeved caliper for classic Corvette and Mustangs back in 1975."

I sleeved a set of calipers for a friends Jaguar a bunch of years ago.. works great, but it was a show car so not used much. easy to do...

 

[unsafervguy]

other than it not being approved by the FAA, therefore and unapproved part?

Owner produced part. Should be legal.

Not so. According to an aug 5 1993 memorandum from the chief council the part must be manufactured from an approved design. Sine the approved drawings do not include sleeves, the part would be deemed un-airworthy.

Just consider it a minor repair and move along.
