I've tried both ways of rehabilitating/rebuilding my clutch hydraulic systems (at least the slaves).
Most of my clutch jobs in the past 15 years have involved new master and slaves.
I simply replace the old master cylinders with a new one since they've been pretty cheap at the time that I need them. But the second-to-last clutch job I completed had a problem - the new slave was beginning to fail within days of bleeding. I spent a lot of effort exploring what was wrong before finally contacting eEuro where they said they'd been getting SOME bad slave cylinders into their warehouse. I had to take everything apart again to send the failed one in and exchange it for another one. The second one has worked without issue.
And then in researching the problem here in the archives, people seem to have routine success with simply replacing the seals on the slave cylinders. Apparently the older cylinders are better built than newly-manufactured replacements. I followed this strategy on my last clutch job by replacing the seals in the old slave cylinder. It has been working just fine since that rebuild.
If I can get cheap ($40-$70) masters as new, I'll continue doing that. I don't like the fuss and muss of rebuilding masters with the fair chance that I didn't clean/bore out the cylinder well enough and the whole thing fails somewhere in the next 8000 miles. I just looked at eEuro prices for masters and they've gone up since I last purchased. I might conduct a wider web search for replacement masters if I needed one right now.
I WILL continue with rebuilding the clutch slave cylinders as I think the chances for success are better than risking a new-manufacture replacement. I've lost trust in the new-manufactured options for slaves after that last round of back-to-back clutch disassembly work.
I haven't done a brake master cylinder in a long time so I have no comment on that topic.
