Problem I bought car with was no clutch and later found out myself, broken gearbox by previous owner happily switching gears without clutch, strange people there are!
First fixed the gearbox, by swapping with another used one. Working on things noticed leaky slave cylinder, installed repair kit seals.
But that didn't fix clutch issue, which was that clutch was engaging at very bottom. And pedal feels was like there were some air in the lines. After several attempts to bleed the lines and several methods:
- pump air pressure through brake fluid reservoir
- sucking fluid out with special pump through slave bleed bolt
- pressing pedal, opening slave bleed blot, letting fluid out, closing bolt, repeating
Decided to inspect master cylinder, also because fresh fluid got dirty almost instantly, which is a sign of wear out seals.
After installing repair kit on master cylinder and cleaning cylinder itself and bleeding in several ways, got no positive change in clutch work. Decided to install new master cause on old cylinder walls noticed quite a few deep metal oxidation spots, which might be resulting this.
When assembling drive train components had to separate shock absorber from the lower fork which was fun:
Aluminium oxidated and bolt got stuck, some cutting and hammering worked like a charm.
