PontiacGP, for you this is probably all road already travelled but just as a possibility for your consideration there was an excellent article called "Braking News", written by Ron Ceridono, that appeared in the November 2019 issue of Street Rodder. Among the items discussed was incorrect m/c cylinder bore, along with samples of the math involved to determine line pressure given a certain bore and x amount of pedal pressure. Now I cheerfully both acknowledge and agree that what the author is speaking about may pertain more to rods and customs than late models but as a reference read it is interesting. The issue is long off the shelf but you might still be able to find it on "streetrodder.com". or someone on the forum might have an extra issue kicking around. The mag itself is an ex-publication; it, like the parrot, has ceased to be, thanks to the indifference of the publisher to apparently everything (except huge profits generated for the benefit of its share and stockholders). It was one of a large group of specialty publications that got assimilated and then eradicated in the last year or two.
Anyway, thought of this article this am and figured it would do no harm to commend it to your attention.
