Morning all,
I have just rebuilt all three single pot non-ABS calipers to install new seals.
Although my outfit has leading links, AFAIK the front splitter is as per standard. However, PO had fitted stainless lines. I noticed when I took the calipers off that the fitting nut did not rotate on the lines and I had to rotate the caliper to unscrew it from the fitting.
That didn’t seem right and at the time I thought I would take care of it at refit but no matter what I tried I couldn’t get any movement of the fitting nuts relative to the lines at either the caliper or splitter ends.
That’s when my stupid took over. I decided that must just be the way SS lines work, put it all back together, flushed and bled the fluid during which process I had to put more than an extra half turn to the RH fitting nut to get it airtight. Naturally this has put a gentle half spiral into the brake line.
Bleeding the system was such a pain that I’m tempted to just dismount the caliper and rotate it the other way to get the spiral out of the line.
This isn’t right is it?
Something should be freely rotating, yes?
The tension in the line will create a tendency to unscrew the fitting until the stress is relieved? (I used a touch of copperslip at the caliper fitting so this is relatively low friction).
Am I going to die?
I’ll take the existential feedback too, but I have cocked up haven’t I?
Cheers, Stu
