Thanks to Lee 98 I rehabbed my leaking master cylinder. I'll share a few photos but first a short narrative.
Only issue I had was separating the master cylinder from the bike after removing all the screws necessary because it had stuck from crud and had to be tapped apart. The piston was in good condition, the rubber was intact. The bore looked good, but I cleaned it out anyhow. The throttle chain/cam needed to be cleaned out and relubbed, as the old lube was dried out or absent.
Reservoir was leaking from the o-ring underneath. Replaced this, the reservoir, cover, and rubber flap inside. I repainted it and it has worked well and not leaked.
Photos:
1. crusty brake fluid on master cylinder
2. cover off. Note lack of lubrication
3. piston pulled out of MC. Was in good condition
4. Master cylinder after cleaning/painting
5. old reservoir/new reservoir. Note crusted and shrunken o ring on original
6. Put together without the cap or grip on
7. Have the cap and grip on now. mirror still not attached
8. MC with attached reservoir all shiny and painted
I changed front pads, added Spiegler brake lines, removed/cleaned/rehabbed throttle body, replaced the cooling fan and rehabbed coolant system. Maybe I'll post photos of those projects if anyone is interested.
Thanks!
