Title: "Lumpy" front master cylinder pull on 1989 Connie
Post by: zetec7 on June 08, 2013, 06:04:03 am
I know, lousy description, but that's how it feels.  As I pull the lever in, it feels alternately easy/stiff/easy/stiff.  Obviously, it needs rebuilding (and it ain't great at the best of times), but at this point I'm wondering if anyone has a wonderful mod they can recommend (eg. "the front master cylinder for a Suzudakawaducatahonda XSRZH-1378 is a perfect upgrade, for cheap!  Get 'em on Ebay for 11 bux!!" ::)), or am I stuck with rebuilding the original & its ho-hum braking? 

I did look at the radial-farkle master thing, but the cost is rather...um...prohibitive, given the state of my currently restrictive pecuniary status.  :-[

Any ideas?

Brake or clutch? Check at the pivot point of the lever for wear/ lack of lube.

Disassembly and cleaning are necessary to determine
condition of MC.  A rebuild may be needed. It's cheap
and usually effective.
If it's too worn or damaged, replacements are  available
on EBay but this too may need a rebuild.
MCs from other bikes may be a mis-match to your system
affecting braking performance.

Sorry, brake master - I should have specified.  The lever is pretty much new, with good lube.  Looks like a rebuild kit is in my future. :-[
