> I've finally got my "restored" '75 TR6 back on the road after a two
year engine rebuild and I've driven about 200 miles. Today, after a 25
mile drive I noticed that occasionaly the brake pedal will sink quite
low without much stopping power when the brakes are applied but will
become firm after a pump or two. The problem is becomming progressively
worse. There is no leak at the master cylinder, which remains full of
DOT 5 silicone fluid and there are no leaks at the front calipers or
rear wheel cylinders. The m/c was replaced with a new one at the
original restoration in 1994.

Jim,
Double check the wheel bearings. If they are set too loose the rotor can
wobble back and forth and push the caliper pistons into the calipers
leaving you with a lot of pedal travel just to put them back into proper
position.
