I'm wondering if there are any interchangeable front brake calipers for my 1973 CB450K6? A previous owner had stripped the bleeder valve threads on the caliper housing and rounded off the nuts on the steel pipe part of the brake line. I'm in need of a new caliper and the hose from the junction box down. Are there any direct replacements besides a caliper from a CB450K6? I've been searching ebay with no luck and can't afford the $275 for a brand new caliper from Bike Bandit. Any help would be greatly appreciated. Thanks!

I might be wrong on this one but I think most Honda calipers are compatible with the CB450 like the CB750, CB500/550 and CB400 Four SOHC. The caliper on my CB500 four and CB450 looks very similar but it might be best to wait and hear the gurus thoughts.

Yes. the 350, 360, later (smooth type after K4) 450, 400/4, 500/4, 550/4 will all interchange.....
The early (finned) 450 calipers are identical to the early 750/4 calipers.....
