semi hydraulic brakes

[surènos]

Can anybody tell me if standard lambretta front disc brakes are any good after being converted to hydraulic & are they known as semi hydraulic I'm looking at buying a gp with one fitted & am wondering what to expect,I had 1 years ago that wasn't converted that was a pain pads constantly rubbed makin nasty grinding noise it was virtually non existant when pulled on ibinned it in favour off drum brakes no such thing as proper hydraulic disc brakes back then

I would have thought that semi-hydraulic would describe a standard cable operation at the lever, operating the master cylinder behind the horn casing...?
So not as effective as a full system, but retains the standard look at the handlebar...

Byron is correct in that semi-hydraulic refers to systems with a cable actuated master cylinder. The cylinder is typically hidden behind the horncast. I have done this on my Special with a PM Tuning front disk. While the shortened cable from the lever to the cylinder does reduce the performance as compared to a full hydraulic system, I can stop it on a dime or lock it up anytime I want and my scooter is fast.

Given the negligible difference in performance, I see no reason to downplay semi-hydraulic systems. A semi can stop any 80 MPH Lambretta just as well as a full hydraulic.
