I've never had a motorcycle, but by the grace (or curse) of God, I've been blessed with two identical 1980 KZ750s, one to ride and one for parts. The front brakes have been sticking... slowly closing down, even while it sits overnight! I pop the bleeder and they're ok for a bit, but it's dangerous!
I bled the lines, and the fluid was dirty, and it helped a bit, but still toooo dangerous. I swapped the calipers, and bled them and it's a lot better, but they still slowly close down over time. I swapped the master cylinder, but cannot bleed it successfully! I open, pump, close, open, pump, close, 4FR (forever!) and nothing happens. Air bubbles keep coming out of the two little holes in the bottom of the master Cylinder's Reservoir.
Any ideas as to WHY the calipers close down over time?
Any ideas as to how i can tell if the master cylinder is any good?
Any ideas on a fair price to have it rebuilt?
Any ideas on a fair price for a new one?
Any ideas on where to get that fair price?
This is my 1st post on any forum anywhere. Am i being too wordy?
