1998 sportsman 500 rear brake master cylinder replacement is different
#1
Hey guys, I just ordered a rear brake master cylinder. everything seems to fit EXCEPT.,... the gold pushrod on my 1998 is hollow. so the foot lever screw and rest inside and does not slide around. It seems on the newer ones that golden pushrod is NOT hollow. So my threaded screw cannot rest inside of the master cylinder. The aftermarket for my year in non-existent it seems. Is there a way to put a new connection on the pushrod to connect to the brake lever? something that would HOLD the golden pushrod instead of my screw that nests inside the pushrod. Here is a picture representing how it kinda looks on mine. (this is not a picture of my exact one) I can take an exact picture of mine if needed. Look at the RED rod. That is coming from my foot brake lever going INTO the "gray" pushrod on the brake cylinder. Since the new Cylinder pushrod is SOLID my break level has nothing to hold on to. hope this makes sense? Is there some adaptor? Any ideas?

Seems like rebuilding your old master cylinder would be the way to go then as the seals were the main problem anyway.The seals would leak/suck air over time from non use.Before the seal kits came out you had to buy the high $ oem complete master cylinders. Then the aftermarket master cylinders came out.If it doen't work,just rebuild the old one.https://www.ebay.com/itm/1999-2008-P...!US!-1&vxp=mtr

Interesting,but no ones posted that I can recall of swapping piston plungers out because the hollow plunger style master cylinder was only used that one year.Possible it may swap over to the new body,but you may end up damaging the seals taking everything apart and swapping things over.
