So 2 years ago I put in a new Perfection-brand Master+Res+Pressure Line, all good, light duty since then, 6,000 miles, 4,000 of that highway, been working at home all summer, so even LESS use...
... then this week, typical hot AH FL afternoon, 12 miles up the highway, A/C ON, engine off for 5 minutes, re-start, 4 miles of stop-and-go, engine off for 10 minutes, re-start, 1 mile into return 4 mile stop-and-go, out of nowhere, clutch pedal has "reverse" resistance, i.e. light for the first 80% of travel, then ultra-STIFF for the last 1-1/2 inches, then weird on the release...
... I nurse it home, park in the shade, 5 hours later, back to completely normal...?? I know brake fluid is made to get way hotter than under-hood temps, but I'm thinking both water and air will expand a lot (boil?) with the temps the Slave-end of that pressure line gets up to...?
Checked the reservoir, level fine, maybe down 1/8" since new, but a bit dirty... hmmm...
Have driven it 2 shorter trips since then, "gremlins" gone, totally normal again.
Anyway, what say ye, RKIs?
