its a calculation of how much force is required in relation to how much force is applied by the pads on the disc.
no
The ratio of brake power output to power input
Brake Thermal efficiency !!
could be the grade of brake pads you use, might have air in your brake systems that you need to bleed, could be low on brake fluid or completely dry.
12%
im not for sure there is a legal minimum but i tighting them to 3 to 4 clicks and the car shouldn't go any where
50% is the minimum legal efficiency for vehicle first used on or after the 1st of January 1968. Before that date the minimum is 40%.
vehicle weight divided by total brake effort, then multiplied by 100
It is used to evaluate how efficient an engine converts the heat from a fuel to mechanical energy.
the footbrake is 50 and the handbrake is 16 on a split system
Brake test is used to determine the efficiency of comparatively small motors. The motor is loaded directly by means of a mechanical brake (load) or by means of an eddy current or a calibrated air fan.
Depends on application. Front only? Rear only? Both 100% Too broad a question
