rear brakes not doing their share on G60'ed urq

[Brady Moffatt]

Hi All,

My still-new-to-me 83 UrQ has G60 front calipers, which work fine. It has
stock rear brakes which don't work as well. They heat up significantly under
spirited driving (so they're doing some work!) but not nearly as much as the
fronts. It really feels as if the fronts are doing almost all of the
braking. On Louis-Alain's 83 UrQ with stock brakes all around, braking is
much more balanced, and, I suspect, stronger.

Have the G60 calipers' extra appetite for brake fluid unbalanced the braking
system?
Do I need an adjustable proportioning valve so that I can get more line
pressure to the rears?

Any other ideas?

BTW, the car brakes straight, and nothing sticks.

Cheers,
Brady Moffatt
