<My 1979 TR7 export seems to have had replacement bracket fitted and the bolts which hold the master don't fit because the head hits the inside of the footrest part of the frame. Pervious owner has ground the bolt head down to a sliver!>

Actually, that's normal, so it sounds as if it is the standard bracket.


<Can I remove the rear brake lever? It seems to be on a square tapered shaft and is reluctant to move.>

Yes, once the brake pedal pivot spindle inner nut has been removed, the spindle can be tapped outwards slightly from the rear, which should release the trunnion lever from the squared end of the spindle.
