brakes little/no effort

I would only use little or no effort if one of the readings is below 50 and the other reading on that axle is much higher, or I know that on that model it should be.

what im getting at is do you guys fail for low effort if the difference is more than 50% with no locks

I'm guessing that these arnt max efforts as the vts device would fail these straight off

If I am understanding your question correctly, then no. The RfR 'little or no effort is not about the difference in the braking effort. As everyone else has said, the VTS device will pass or fail that for you. Little or no effort means exactly that. I should imagine (with no evidence supporting my theory) that the RfR isn't just a straight 'no effort' because you will usually get some drag from the transmission giving you a small reading - maybe about 20 - even when the brakes are totally seized. So as I said in my last post, I would only use that one if the loss of braking is extreme. 50kgf or more I would issue a manual advisory for low effort.

Basically if it locks it's a straight Pas if not the VTS Device decides as aylesburyjock said.

Little or no effort is exactly as it say on the tin, virtually no reading

Note the low effort and allow the VTS Device to decide the outcome motman. All changed when the new procedure was introduced mate

The vts will decide the total braking efficiency and imbalance, the tester will have to select the little /no effort rfr manually if this is the case.".
So if in your opinion you consider a low reading of say 50kg then fail it, taken into consideration wheel lock etc

I disagree entirely!

The VTS device calculates overall service brake effort, overall parking brake effort, and imbalace across each axle.

Unfortunately the VTS device is not blessed with the intellect to realise that with readings of 300 kg and 50 kg across an axle there is clearly little or no effort at one wheel. Only a human can do that. The VTS device can only make simple calculation that the difference is greater than 30%.

Similarly the VTS device cannot make an intellectual decision that the brakes across an axle are increasing and decreasing at an even rate. Only a human can do that.

Neither can the VTS device determine excessive brake fluctuation. Only a human can do that.

Once the brake figures are entered, the VTS device takes the tester to the results screen which gives pass/fail results for service brake, parking brake and imbalance you may have noticed there is still a link available to go back to the brakes section.

Thats for us humans to enter all the other legitimate failure items as mentioned above.

Yes the VTS device can give a pass, based on the three parameters it is set up to calculate, but it is not the be all and end all of brake testing. It still requires s a brain and some intelligence to work out that there may be other defects present, as already mentioned above, which warrant failure.

Ouch!
