Hi, I have just had an almost identical problem on my Prelude vtec.I had a
severe wheel wobble at high end braking and the car would judder felt like
it would fall apart.

I tied to emove the pads to check fo any run out on the disc's and it was
then I found that the caliper was not releasing when I stopped braking
causing a slight braking effect all the time and overheating so that when
you did brake the disc was distorting where the two plates ae joined.

Stripped the caliper down and cleaned both piston and inner surfaces
rebuilt, had to have disc refaced but perfect now. Hope this helps.Vic
