The transverse rear brake pipe may corrode excessivley but is impossible to fully assess from underneath. This can be very much 'localised' (as opposed to general) and you can bet the bit you can't see is the bit that matters. To view it properly, the rear suspension must be fully extended no matter what! and then viewed from the offside (especially), over the top of the rear wheel I don't get too many of these to test but two of the last three have failed, an '05 plate being 'ticked' in the 'D' box, my point being if we were testing to 4-2-2 this would not have been found untill year six; too late I fear!

VOSA a little while back came up with a new idea about brake pipes, and my latest experience I thought I should share with you NT's Will have to forgive until I remember make of car it was , the nearside front brake pipe which goes to the flexi hose had ONE support clip fitted as per manufacturer recommendations on the inner wing. During the lock to lock check the brake hose has more than sufficient room to move, so nothing to say there then, however after jacking up the front of the car and turning the road wheel on full left hand lock, examining the condition of the brake hose, some really top notch experienced person put a braded hose on in place of the standard hose, but the diameter is less than the standard hose and the security of the braded hose could not be secured to the inner wing bracket as per the manufacturer recommended method, so the expert left it insecure, and there is no reason for rejection for that. The testers manual reason for rejection says that a rigid brake pipe must not be free to move with vibration, then in the information column recommendations are given that says a security clip missing is not necessary a reason for rejection, but this car did not have a security clip missing, it had an insecurely mounted brake hose which was pulling on the brake pipe on left hand full lock, which would eventually fracture. Maybe somebody in VOSA should put a failure point in for a brake hose not secured as intended? Dave

If you felt a failure was warranted Dave, the rfr covering the situation is 'a rigid brake pipe inadeqately clipped or otherwise supported'

While I understand what the testers manual is saying here;
'a rigid brake pipe inadeqately clipped or otherwise supported'
It is the flexi hose that is insecure in its bracket, which is pulling on the the brake pipe that is the problem.
No reason for rejection for that one, and its not VOSA at fault because nobody who is a professional engineer would fit a brake hose and leave it insecurely mounted?
This is the point based on evidence that should be stopping people repairing their own vehicles, and only permitting a competent organisation to carry out the repairs.

I understand your point Dave, but both the flexi hose and the rigid pipe are relying on the mounting bracket for anchorage and support, so the situation is covered. You were worried about the rigid pipe fracturing because it is able to move where it should not, that demonstrates that it is not being adequately held, so there is your rfr. Have to agree, by the way, on your idea that only qualified technicians should be permitted to do repairs. I think we've all seen enough bodging to support the idea

had one of these in today and an advisory was noted the nearside rear brake pipe where it sit on top of the chassis was slightly corroded notorious for this.
