Lifeboat “launched” and on its way to pick you up;). You now bring in rfr8 into the discusion and play this off against the other. Carrying out the first part of the test, ie individual wheels we are looking for two things
a) Little or No effort
b) record readings and wheelslip for efficiency calculations.
So very much unconnected, as a brake could be failed for little or no effort and the readings recorded can still and will contribute to minimum efficiency calculations.
The second part is rise and fall, bind, Severe grab,judder and out of balance on the front axle. Again totally seperate inspection to the first part.
One brake could bring about multiple fails.
The issue over a fault causing the high reading. Vehicle knoweldge and the ability to advise allows the humble TESTER to pass on that knowledge to the owner and make descions on pass fail, depending on the vehicle and our knowledge of it. But if you do not know the vehicle you take it as it is and apply the manual.
Your assumtion that TESTERS do not understand “rate of increase / decrease is so off the mark:(.
Your last post David was again the ultimate in “pointy hat moments”, “OH” to be as intelligent as you and not just a TESTER:?. I think “WES” sums it up well in a funny sort of way:P.

Hi RFR,
I obviously interpret the meaning of regulation (3.7A.1a) in conjunction with regulation (3.7A.8) differently that you:). My interpretation when reading it is that before a tester decides to fail any individual brake using (3.7A.1a), finish the complete brake test, then use regulation (3.7A.8) to decide if the minimum efficiency has been met, if so then that part of the test has passed. If now “my understanding” using regulation (3.7A.5C/6) as previously said the service brakes don’t work together at about the same rate, “rise and fall”, then using that regulation “(3.7A.5C/6)”, the service brakes would be issued with a reason for failure, VT30.
Your introduction of the brake defects regarding “brake grabbing or judder I never brought into the test, this is because those faults did not exists;). My understanding of Brake grab and judder using the regulation prior (3.7A.5C/6) is logically placed in the correct position before (3.7A.5C/6) using (3.7A.2b),also regulation (3.7A.2a) a brake binding, because if the brakes have a significant bind, or severe grab or judder, then the regulation (3.7A.5C/6) rise and fall could not be used meaningfully.
The brake out of balance of the front service brakes was also not mentioned (3.7A.2e), because no defect was present. RFR you also have introduced a lot of new parts of the test which were not showing defects:)
Sometimes I feel the wording used by Wes is not always constructive, his volcabulary suggests that he is a bit of a loose cannon:shock:, and I don’t mean a quality cannon camera either:D
