Quote from: Speedy1959 on Thursday, 29 June  2023, 01:34 PMI dont suppose there is a way of mounting a caliper (from another bike model) in a "non upside down way" is there ?
My Previous CB1300 had this and the that too had a conventional swing arm!



@Speedy1959 there is - but how its done I don't know. There was an engine tuner on the old (original) org called grumpy who apart from tuning engines (particularly Busa) used to modify frames a tad and I seem to recall that he fitted a Busa swing arm to a 14 and that had the caliper mounted on top rather than below. Now - whether he had to modify to fit or re-align chain run, I have no idea. But I have seen it done

@Tony Nitrous you have some Busa's - in your opinion would this be possible?

easy enough job, you could use a rear calliper from a GS500 as they sit on top, you would have to weld a bracket to the top of the swinger for the torque arm though. 

Using the 14's caliper mount casting?
Caliper sits right on the disc?

the 1400's calliper hanger looks the same as the bandit 1200 (but i need to measure it) on the bandit you just swing the hanger to the top and bolt the GS500 calliper on, the only difference between both callipers it the mounting holes are at different sides. one for top and one for bottom.  :onya:

I obviously use my rear brake a lot, when I ride the likes of the Oxley before I get to Gingers Creek from Wauchope end I can stand on it and there's nothing there. Thought it was a 1400 thing but when I did it on my FJR same thing happened.

I can actually lock my rear wheel if I try!
It doesn't happen easily or accidentally ( I wouldn't want it to), but it can be done.
I don't think I'm looking to weld and fabricate a top mounted rear Caliper.
Just wondered if there was a simple "bolt on" solution, a bit like the front Caliper alternative.

Mine is/was a great rear brake. Never locked it up but had great stopping. Hopefully tomorrow will bring it back to normal. Caliper off, apart, clean, reverse bleed. Cant believe i forgot about reverse bleed, guess i a am old.  :grin:

rear brakes on modernish bikes aren't meant to be to powerful for a reason, last thing you want in an emergency is the rear wheel to lock up !!!! look back at some older bikes and they had a very long brake pedal so all that leverage could lock up a rear brake !!!!!!

My 1976 RD400 locks up real easy the lever is about a foot long, not much engine braking in it either.

Tally

My rear brake works a treat, never had the feeling that it's not doing it's job.
