The front master cylinder on my '81 Interstate started leaking & instead of rebuilding it, because of the scuzzy reservoir & the overpriced re-build kits, I bought a brand new m/c off of flea-bay. The seller listed it as a direct replacement for "80-'81 goldwings. Got it mounted up, bled it, pressurized w/ a nice & firm lever.....
Now comes the fun stuff... connected all the lines, going thru the prcedure of evacuating the air from the lines & have gone thru damn near a pint of brake fluid trying to get a firm lever again to no avail. :head bang:
Used a mity-vac to help eliminate all air from the lines & tried the rubber-band method of pulling the lever & leaving it set overnite also.
The lines look to be in good shape, w/ no swelling & might have been replaced w/in the last 5 yrs. or so...
The bore on the new mastercylinder is 2 mm smaller than the oem ( 14mm vs. 16mm ). Could this be the reason for no lever firmness??? I'm at my wits end trying to solve this....
Thanx in advance...
