Different one this time, both front brakes bind at odd times, can be from cold and hot, and if I hit the brake pedal hard a couple of times (when stationary) they release.

So I presume it's something to do with the balance bar? I'm using Sierra callipers (new) with Ferodo racing pads.

Sounds like your master cylinder push rods aren't able to completely return. Adjust them in the clevis on the pedal to give slight play at rest.

In addition to the above you might need a return spring on the brake pedal

Thanks chaps - I'll give that a go....
