New slow jets work wonders!

The front brake on these bikes will squeak and I think it is something you have to live with.  Mine squeaks under heavy braking and usually stops squeaking when it needs adjusting.  It always works better when it is squeaking. 

Applying a bit of physics, in order to acheive a reduction in kinetic energy the brake, by applying friction to the disk, turns that energy into heat, light(if the disk gets red hot) and sound.  In the seventies, Honda brakes were so bad they needed to make a sound to inform the rider that something was happening.   ;D

Now Now Florence, remember in the 70's that Triumph had a twin leading shoe conical hub brick and norton had a lockheed sieze up, neither of which worked for long if at all so Honda's disc was a revelation, except in the wet---but then who want's a locked up wheel in the wet anyway

florence:
You are right Bryan, I was only joking, the British one's were much worse. 

In all seriousness the CB500/4 brake I have is actually really good for what it is.  There is somewhat a lack of feel which adds to the perception that they don't work well, but,  when I conducted a stopping distance test on a quiet road, in the dry, from 60MPH, I was very surprised how good it actually was.  The only brakes on a bike I've ridden which were better were the ones on my CX500 which were phenomenal.  As that is the newest bike I've owned (1979 model) I am not really qualified to comment authorititively.

Years back i twin disced my 500and was going to Skellerns in Worcester (theres ablast from the past)to collect some urgent parts when a dear old lady (said through gritted teeth) stepped off the kerb about 10ft in front of me into the big puddle caused by the torrential rain----hence why i said who needs a brake that works in the wet............... I added handlebars, headlamp brackets and headlamp shell to the parts order!!

( i must apologise for changing this diverting this thread to brakes.

Just to update, I (think) I have got rid of my brake squeal.
I split the calipers, gave a small sqirt of brake cleaner spray around piston/caliper; & notice some early signs of rusting around the outer diameter of the brake pad backplates; so I emery'd that away, and applied a fine film of copper grease.
- scared silly about any of it contaminating pad material or discs.
 but it seems to have cured the squeal..... for now at least!

 & to top it all, today she passed the MOT, Yessss!! & not even a single advisory.

happy bunny!
