Brake Hoses

Your comparisons with other criteria and examples of worst case scenario are not really relevant.
The models of vehicles that are mentioned in these posts are particularly prone to having this defect present, more so when they have reached a certain age and the problem has not been addressed.
The current vehicles that I look out for are the Clio 2 and early 3 front flexi hoses that are fitted with bend restrictors at the caliper end , the Fiat 500 and KA 2 that have restrictors on the front where the flexi hose is attached to the vehicle body , the Mazda 3 has a problem with the ferrules beneath the restrictors also.
What you do with this information is up to you, only the tester can make up his own mind based on his experience and what is presented in front of him.
If there is anything that I can gain from this exposure is the thought that I could have possibly saved someone's life by making the right call then that is good enough for me.
If I was to look at a hose rob and be suspicious and unsure then it would be a pass and advise but these hoses pictured are clearly recognisable as not being in that category, it is experience and knowledge here and now on current vehicles that we see nearly every day on a repetitive cycle that enables us to build these pictures and learn from them.

I understand where you are coming from and I noted from your earlier post that bend restrictors are slightly off your radar but my point is that more care and attention is required especially on the models noted in this  thread, on cases where the decision is unclear then continue to advise, but I would not say nothing when presented with these particular model vehicles as they could lead to a serious failure if the restrictors are expanded to a notably different extent than you recognise to be the norm.

I was also aware of them on the cavaliers et all in the 80s they were a familiar and recurring issue in the same way as they are now on the models I mention in this thread, I was involved more on the service and repair in those days and the problems were well known and dealt with because they were looked for if you took an interest in safety rather than on earning a quick buck, for the models I mention in this thread of more current and familiar models of today I believe it is a waste of the test fee for the customer if attention isn't drawn to problems that arise in this area on these particular items.
You stated only the other day in another thread how you would like to see common problem areas shared that concerned specific vehicles . ( Ford Focus hidden corrosion I would like to talk about but would perhaps be better off keeping to myself if this thread is anything to go by )
You don't have these problems with a horse

what part of im out aint you getting?

At the end of the line its alright , you have to live and let live. 

when the punter turns round and says it should have failed, sorry ..minor major dangerous..

The ferrules are just a continuation of the metal brake pipe, as with any metal brake pipe joint that is excessively corroded = fail.

As a workaround
