Gecko we would like some more info;
Did the wheel lock up and stayed locked?
Did the situation clear itself?
And the last time the fluid in the system was replaced?
Reading on the web it occurs to me that abs may pose more problems at the wrong time than the advantages it has if left to "fend for itself" as time passes and parts start to corrode due to lack of use.
Here is one of the better diagrams on the workings of the system;
And a picture of how these units look nowadays;
My only bike with abs is the cb1000r and i test both brakes regularly on a flat grassy surface at slow speed, i also have a special bleed nipple which has an adjustable outflow and i use this to expel enough new fluid to replace the pump body's internal old fluid which mixes downstream with the new fluid when the abs is made to operate.
After the excersize i replace the fluid again to make sure it has exited the system.
All this would have made better and more reliable if there was an abs cycle built into the system from the factory to replace the fluid inside the modulator body.
The abs selfcheck includes a continuity test for all solenoids and the pump to ensure all parts are not open circuit and the sensors are working properly when the vehicle starts to move above a set speed.
But these tests do not include if the parts are stuck and the user is unaware of this until.......!
