Topic: Wanted - Cb500/4 brake caliper

[Botaylor]

Hey guys,

Chasing a decent 500/4 front brake caliper. One I've got is seozed and bleed nipple is all chewed out.

If anyone has one in good condition let me know.

Cheers
Brad

I think I've got one. I kept it because I had not yet learned the grease gun technique for getting the piston out. It is clean, disassembled, has a new seal to go in but does not have any  brake pads. Bought a different caliper off Ebay that is currently running well.

PM me and I will see what they are going for.

Screw the grease gun hose into the brake line opening a few turns by hand until snug.  Pump it full of grease and it should pump out the piston fairly easily.  Clean out the grease and spray clen the caliper with brake cleaner.  If the bore for the piston is not marred you should be fine for replacing piston and seal and using your caliper.

Pick up some parafin wax (kilo) and a small pot your caliper fits inside of without too much extra room (to minimize the amount of wax needed.  Using your grill or a burner outside heat the caliper and wax in the pot for 30 minutes.  Carefully remove the caliper and then while hot you shpuld be able to extract the bleeder.  If it is broken off then it should be able to be extracted...the wax penetrates the area between the caliper body and the bleeder screw and lubricates it so it will turn out.
you can drill it out larger and fit a brass sleeve that is a press fit into the caliper body with the internal dimensions threaded to fit the brake line but that is involved and would require more info.

Let us know if you can remove the piston and post a photo or link with good pic of bleeder screw so we know what you are working with.
