After an extensive spring upgrade blitz, all that is left are new SS brake lines, which should be here any day. When the sun finally popped out on Friday, couldn't resist the temptation to slap on the old lines temporarily, as I have speed bleeders on all calipers, and brake fluid changes are a snap.
Could not get the rear brakes working properly, and tore apart rear master to find a cracked piston seal. On further investigation, these cup seals, or the piston assembly is no longer available for my '78 KZ650 C2.
I have posted an ad in the classifieds for a rear master, but I don't really need the whole works, just the cup seal for the piston.
Has anyone ever checked with seal or hydraulic shops to find a replacement cup seal for the piston? How about a master from a different bike? There are different places with master re-build kits, but not many I could find for the rear of the 650. I used a kit for a 1000 to re-build my front, but am having trouble locating one for the rear. Kawasaki.com shows part #'s 43020-1004 or 43020-1007 for the piston w/seal, but no longer available
.
Any suggestions greatly appreciated, as this is the last holdup before pure, un-adulterated riding fun
. Even worse, my wife and son are gone for the weekend, and I could have had 4 days torturing the odometer .
. Thanks.
