Answer
Hi Carla.  Sorry for the delay - I had a BIG computer failure.  Took 2 weeks to fix.  

The MGB has no more brake problems than any other car of that age.  If the brake pedal goes to the floor, then you probably have a loss of brake fluid.  Fill up with fluid rated DOT4, press the pedal a few times, and see if it holds pressure.  If it does, you will need to bleed the brakes.  If the fluid leaks out, try to find the leak.  It could be at the master cylinder, the slave cylinder underneath the engine, or the flexible hose that connects to the slave cylinder.  

The brake lights are operated by a hydraulic pressure switch.  No pressure = no brake lights.  They should work OK again once you fix the leak.

The VIN number will be something like G-HN3-123456.  It is on a small plate attached to the right hand inner wing, near the radiator.  There is a second plate by the bonnet (hood) lock, with the body number - this should be ignored.
