Brake rotor info

[Anakist]

I have a 96 and I want to know the PCD and offset for the front brake disc.

I don't have access to the bike ATM and my verniers have a flat battery anyway... Yay digital technology.

What is a PCD and ATM ? (sorry, I don't really keep up with abreviations like I should)

[sledge]

PCD: Pitch circle-diameter. The diameter of the circle formed by the ring of bolt holes that hold the disc to the hub, taken from the center of the hole.

ATM:.......dunno for sure, could be "At the moment"

ian....go drink more beer

I have no further useful help right now

most.... most     suzuki's are the same....88-2005   


why do you want this number?

[ohgood]

Pitch Circle Diameter eh ?

Hmm, from the description, that sounds more like 'bolt hole circle'. Or maybe they're the same, just different descriptions depending on if you're the drafting type or the machinig type ?

I've never heard it called that is all.

Yeah I am looking for the diameter of the circle that the bolt hole centres are on.

I am getting a brake rotor drawn up as a dxf file and just need the size of the bolt and the distance apart.

PCD is the recognised term used to describe the diameter of a ring formed by at least 2 holes (tapped, untapped, blind clear etc) in a component part. e.g car wheel, car flywheel, a pipe flange or a brake disc. Never heard it called anything else............least not in my part of the world. To calculate the PCD measure from the center of a hole to the center of the disc, that gives the radius......then use pi.


kenny? I am off right now to take you up on the suggestion.....cheers matey.
