Broken brakes and the runaway Suzi...

[What?]

Clamp the hose out of the master cylinder with smooth-jawed vice grips or a G-clamp to block it. Now squeeze the lever.
If it is un-squeezable, the problem will probably be air in the system. If you can squeeze the lever in, the master cylinder seals and/or piston have the F syndrome.

Just a thought - your bike doesn't have the brake line pressure-driven anti-dive system on the forks, perchance?

I was thinking the same thing.

Those crazy 80's and their anti-dive. What a decade.

Interesting idea, unfortunatly the bike has braided lines!

No I dont think so, both systems appear seperate to me.

I will bleed the system again today.

although it may not be visible, you may have a little fork oil on your rotors. give it a clean with brake cleaner and test.

i had the same with another bike awhile back. i left a tiny bit of grease on the rotor (from dirty hands) and the bloody brakes behaved exactly like yours.

oh cheers, yeah that could be possible... i cleaned the roters using dishwashing liquid and hosed off? Did not make any diference. The rotors look dark instead of bright and shiny like they used to.

i would use some sort of solvent. dishwashing liquid is a little slippery for my tastes!

All sorted...

back from Motohaus and a new set of pads fitted... solved the problem! Pads were glazed from the heat! ...must have been going fast enough Archer ey

More than likely your calipers are (were?) seized and they were holding on which is what caused them to glaze.
