Good Afternoon all,

Could anyone tell me where I find the fail for a cracked brake vacuum pipe it's not leaking/sucking etc and the pedal feels fine it's just the condition of it I couldn't find it anywhere when I looked.

Thanks in advance 👍

Obviously advice should be given to the presenter before it progresses to being an issue.

1.1.20. Not in use

A testers manual written by ex HGV mechanics can only provide what they know. When they get to the "Light vehicle engineering" experience, it is clear that not enough experience and understanding is present, so they just write it off politely by saying what I wrote in bold above.

Putting aside what I've written above, it seems clear to me that DVSA have tried to write the manual to accommodate many classes of vehicles, however, you just don't do that if you have not got the experience to do it correctly. The evidence speaks for itself.

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Cheers guys that's how I ended up reading the manual in the end the condition of the pipe was terrible but like I say no effect to the pedal and no noises of suction from the pipe so i passed and advised and showed the customer, can't believe I couldn't fail it 🤷

That's how it is with many issues in the test, however this has more to do with the 'minimum safety' level of the test, than Dynamo's dislike of DVSA personnel. Rather than believe it was a conscious decision by those responsible,due to the fact it is not causing a problem 'at time of test'. He would rather belittle their ability to understand their job.

It might come across that way, but the true as I see it is DVSA staff are from a HGV background and not light vehicle. Nobody understands everything and the manual speaks volumes about problems, hence the questions raised in this thread that the manual clearly does not cover. You can't argue about minimum safety standards with the manual when DVSA clearly have not put guidance in there. Sometimes you just have to accept that DVSA have taken a few serious steps backwards from the last manual, which I thought was must better than the current manual.

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.
