Re: [AMC-List] Rear disc brakes (was: pulling an axle)

["Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx>]

"But on the clamp-on disk brake setup Mark points out, the
brakes are trying to rotate that bracket on the axle tube;
that's a lot of force. I think the clamp on system is brilliant
though, it lets you get everything perfectly aligned, adjusted,
tested, before welding on. A bolt as pin, into the axle tube,
probably works, but seems long-term scary to me. Suspension
parts get soaked in water and crud, take a lot of forces,
and are largely ignored."
---------------------------------

I agree with ost of your comments, but look at your suspension. There
are only a few 3/8" bolts holding the whole shebang in! Rear leaf
springs have two in front, two in back on the shackles, that's it. A
grade 8 bolt should take the necessary force of braking with no problem,
but you can drill for two. With the weld on brackets you put the rotor
on, bolt caliper to bracket, then slip caliper over rotor. Rotate until
it's where you want it then tack and check. As long as the rotor isn't
contacting the caliper all is good. The caliper will align the bracket
just fine, so there's not much difference. Anyone can drill and tap a
hole without much of a problem, welding is a different story! This is
obviously working for stock car racers, who are on and off the brakes a
lot more (and a lot harder) than a typical driver, so I'd say it's been
field tested!
