Is there a specific tool available to clean the bore holes in the caliper bracket for the guide pins? I have seen these brushes online [image] I’ve seen these brushes on amazon and it seems like this would do the trick? I just don’t know if there’s a specific tool for this purpose to help clean o…

I imagine most brake mechanics could have the bracket holes cleaned without a special tool in less time then it took to start this thread.

This is not something I’ve ever done that I remember but I keep a supply of Qtips on hand. If you really gotta use a wire brush just use a rifle cleaning kit.

Use brass or nylon so you don’t damage the bore. Any bracket I’ve serviced… if brakleen couldn’t flush the crud, it got replaced.

I chuck a split mandrel into my drill and insert a piece of crocus cloth into the mandrel. [Using The Slotted ("Split") Mandrel] Tester

[image] Tester: piece of crocus cloth into the mandrel. haven’t heard that term for years would that be the same thing as emery cloth?

Emery sheets have block-shaped grit particles that cut slowly. Crocus sheets have a soft abrasive similar to 1500-2000 grit that’s good for fine hand-polishing of soft nonferrous metals. Tester

Thank you for that information the reason I asked was that I used emery cloth back in the day when you could still get a rebuild kit for brake wheel cylinders although I probably just aged myself. :laughing: :roll_eyes:

Yeah that’s what I was thing too. I wonder where that disappeared to in 50 years. Don’t know what kind of sandpaper I used but the drill was a maning bowman plug in.

As long as its not the same as a loincloth :grinning:

I used a wheel cylinder hone to rebuild wheel cylinders. Even though I live in the rust capital of the world I have never had a problem with caliper pins. Mine usually come out clean and I coat them with Syl-glyde before I put them back in/
