Stop in for a cup of coffee

Used to. Many moons ago. Didnt think kits were so readily available.
One thing, there used to be phenolic pistons, they were prone to cracking and if worn they would wedge in the bore and drag.
Not sure what the appropriate lubricant is to use nowadays, but we used brake fluid to lubricate the rings to assemble.
Big thing was to loosen bleeder before you start,if you break it, then get a reman caliper,time better spent elsewhere.
Yeah. I have always just bought new or reman'd but no one local stocks these calipers and rockauto, i'd have to ship the old ones in for core charges, not sure how that works exactly. Meanwhile, I can get the rebuild kits for 1/4 of the price and now core. The core charge is more than the calipers themselves but I think i have to pay shipping on top of that. plus the polara is about learning new things. Which is why I am converting BACK to points.
