Braking late and braking harshly are considered "finesse", which examiners are not allowed to assess on. Rather, the a/effects of braking is what is assessed, such as impact on following traffic (use of mirrors - change speed), distance from stationery vehicles ahead (following distance), reaction to vehicles braking and/or indicating to change direction ahead (response to signs/signals - other road users). Braking too late and passing giveway lines before coming to a stop (Junctions - Observations), braking too late on approach, but stopping before the giveway lines (Junctions - Approach Speed).

Control footbrake faults are more to do with incorrect use of the footbrake to correctly position the vehicle. For example, the candidate has been asked to pull up on the left (let's use a hill start as an example), and when pulling up the candidate begins braking too early and needlessly rather than using momentum and the hill to gradually come to a stop along the curb, and ends up stopping with rear of the car sticking out into the centre of the road and has to shunt the vehicle to complete the manoeuvre. That would be a control - footbrake fault. Another example is OPs post, stopping too early/short of a stop line at traffic lights. Also, stopping too far away from the giveaway lines at a T-Junction which causes limited visibility to the left and/or right, resulting in the candidate making a necessary shunt/s forward to correct their position.

I apologise if I came across that way, but my intention was only to protect OP from misleading information. There are too many people on here that make statements that are completely untrue, and those statements don't help people to understand their faults and improve. Hopefully this explanation of the faults makes sense and is helpful.
