My slider seals turned up today, both of them, they both look ok, the ones from Sprint Eng say Made in Japan, so on the basis that they're better quality, I fitted them. They both look better quality than the oe ones.
Refitted the calliper got me bits from 1/4" to 3/8" then to 1/2" for the torqueing. Panic, felt like I'd stripped the thread, 1/4 - 3/8 adaptor sheared, lucky I had another.
Glad I did this cleaning job or wouldn't have spotted those damaged seals. Lovely clean in there now, 'til it goes out in the crud.
Don't it take ages to do these little jobs.
