[Healeys] Front disc conversion - picture gallery

[Greg Lemon]

The front disc brake caliper on the BJ8 is similar or the same as that used 
on a TR6, and the Toyota 4 pot conversion is well documented in the Triumph 
world, the article in the link has some comparison numbers for before and 
after braking going from the Girling calipers to the Toyota 4 pots.

Different car, but the same brakes, so may be somewhat relevant.
