Brake questions

I am a streeter and
I have had great success with the KH 4 piston set-up, and silicon fluid. Zero maintenance since 1999 when I installed them.
I run 235/60-14s up front on 7.5" aluminum rims. and I run the 10x2 rear drum brakes,with 295/50-15s on 10" rims,and with NO brake proportioning.
The drums are also zero maintenance. The rear brakes do a lot more work now with zero proportioning, and the car has excellent stopping manners.
I run a manual trans and with nearly 11/1 Scr, she has a lotta compression braking.

In 125,000 miles I have replaced the rear shoes exactly once, and the fronts not at all.
By running the front wheel bearings on the loose side of the spec, I get just enough knock-back to be able to coast nearly a mile from 65 to 25, in neutral. From 25 to zero is also a very long distance,but putting it into first gear gets me 3400 rpm, and at closed throttle,it slows down in a hurry. Then I brake for a couple of feet.
I live in the country, so not a lotta brake action going on, until I get to the City. And in the City, the speed limit is 30mph, and there is rarely traffic, so again very little brake useage. And in the City, I usually behave myself.
Gosh, I haven't even looked at the brakes for maybe a decade or more. Hmmmmmmmm
