type44 voilent shaking when high speed braking

[Doyt W. Echelberger]

My 87 5ktq did that when the right front wheel bearing failed in a very
unusual way. It didn't rumble or make any of the usual wheel bearing
symptoms, but the whole damned rotating assembly was wobbly in the hub, and
the pressure of the brake shoes disturbed that equilibrium when the brakes
came on. The whole front end would shake. They had to drill out the remains
of the bearing, but they saved the hub and nobody got killed.

Yours may be something else, but that's what happened to me.  It wrecked
the front brakes, and even required a new caliper and rotor.
