The UK MOT method for testing brakes was pointless.  It did not test a brakes efficiency at converting rotational energy into heat, but just how good it was as a parking brake.  Drum brakes always passed unless really awful.

Ovality could make them fail.

When I started to drive MOT testers used to take cars out for a test drive which included a brake test using a portable accelerometer of some sort.
I had a 1929 Austin Seven car that had only the rear brakes operated by the foot pedal and front brakes operated by the handbrake lever. Because an emergency stop required foot and hanbrake to be operated I had to drive while the tester sat beside me with the test meter.

When I take my Discovery in for an MOT they still do the test run with the portable kit as using the rollers with a 4WD can wreck the xmission.
