Now fellers we ideally should be making sure that our roller brake test covers are in place each time we drive over them, and we should also ideally carry out an underside inspection before roller testing, here is the first example why;
The picture (inverted) shows a Ratchet which is normally used in our industry; however somebody has made a decision that it is safe to be used to locate and secure a Ball Joint Shank in place.
The problem;
If when driving into the Test Bay the front independent suspension bounces through the rollers, as you know it will, if the ball pin shank departs the stud axle, it may do, the wheel and suspension will move rearwards and possibly cause damage to the flexi brake pipe, outer wing and any plastic coverings fitted, your fault unfortunately.
In this second example, here we have a ball joint located in the stud axle were the securing bolt and nut are free to move, they may not, but it may still be insecure, again the ball pin shank may avertedly drop out of the hub assembly, thus could cause unnecessary damage. I have loads of examples like these, even some were garages have left sub frame bolts insecure, and I mean just put in finger tight not even fully screwed home.
So as can be seen the lower ball joint shown has not been correctly fitted, this was presented to me for a mot test. The ball pin shank not shown could quite easily pop out when in the roller brake tester. The other surprise I had was when I looked into the Regulations; I couldn’t find an RFR for a loose ball pin shank, only the securing nut? (Please note suspension and not steering)
Now you may think that’s ok, but if the ball pin shank is worn, or the bolt fitted was the incorrect type, then the ball pin shank would be insecure?
Hence RFR (2.5B.1a) would not apply.
Now if the independent suspension system has an antiroll bar attached to the lower suspension arm, it’s not much of a problem because the ball pin cannot pop out, or at least it would be very difficult. But if it could during RBT, the wheel could rip back the outer wing causing serious unnecessary vehicle damage?
Once you start on topics like this the reasons for doing the brake test last are endless.
Pictures to follow

Hi Testers I have not forgot about the other issues with the brakes, I know its a long slow lazy delivery, but its the best I can do, and like British Rail said, we're getting there?
I am having a problem uploading the pictures for some reason, any help would be appreciated on methods of upload other than file attachment, if any
Thanks
David

Hi Matt
As you experienced the malfunction of the ABS sensor when collecting the vehicle, the road test not being part of the MOT test, then whatever happens before the vehicle is in the test bay and registered for a test doesn't count. If VOSA and I know they haven't had issued a special notice with new instructions then those instructions would need to be taken into account.
If during the mot inspection using Regulation (3.4) the ABS lamp works as normal, then you have carried out the minimum requirements as stated and cannot be expected to know anything else. When you collected the car, the road test, you noticed a problem with the ABS lamp operation, which worked fine during the official test routine, so a VT32 is the appropriate action to take, you have done the job correctly and should not worry about the defect present, which is normally down to a worn reluctor ring, or faulty wheel speed sensor, or malajusted wheel bearings, which you should pick up on. The only other fault I have know to cause the ABS lamp and Traction Control to function is a worn shock absorber (damping).

Hi David
I did inform the garage owner when i took it back about the ABS light and explained why i, in my opinion, had to pass it. But after i had explained it all he knew about the problem and that was one of the problems he had to fix!! I wonder what VOSA would say regarding this if an appeal occured? Would they believe me? At the end of the day it would be my word against theres. If any VE reading this would be helpful to get your opinion.

Hi Matt
With respect to the ABS light function, like you said if it works correctly in the test bay, nothing to say, its ok, but if you drive the car for any reason, ie collect or deliver the car and then notice a problem, if when collecting the car you notice a problem, I would have issued a VT32 advising of the fault, if delivering the car I would have advised the person receiving the keys from me at the other end, and possibly made a note on my VT40 back at the station.
Its alwasy better to cover yourself because you can never know what happens to the vehicle once its left you and goes out on the open road?

the fault is more likely mechanical then electrical , i.e. cracked sensor ring .
this means that the abs will do it's normal self check & appear fine , it is only when driven over a certain speed that the abs computer realises it is getting a dodgy reading from 1 of the wheels & puts the light on .
as posted above though , if it was ok when tested then no problem , we are mostly all the same in that we drive cars into the garage , do the test & then drive them back out .
no road test means that a fault occurring over a certain speed will never show up on test.

If the faults not present at the time of the test you have no option but pass it. Same as if we were to test drive every car after we test them I'm sure we'd find faults that we couldn't find during the inital test.
Have to say I've seen this fault on many a Vauxhall but I don't have the answer for it sorry.

| Today i tested two vehicle, one after the other with exactly the same problem. What are the odds!! We carry out tests for the garage up the road from us. And to help them out i usually walk up and get them. Today i was given the key to a vectra. Got in, started it, took a glance at the dash, noticed the ABS light and that it did what it should do. Then started to drive down the road and then in all its glory the ABS light comes on. Drove into the test bay. Turned off the engine. Got the details and logged it on. Then checked the oil for the emission test and started it up. ABS light did exactly what it should. And it also continued to do so during the test. I also checked it again after i had parked it in the parking bay. So i passed it. Then when i took it back to the garage the ABS lamp came on again. So im wondering what you other testers would have done. If it was like most of the cars we test, driven straight into the garage by the owner then i would have never known. But because i drove it i knew it had a fault. But at the time of test in the test bay it did exactly what it should do. And when i became a tester nearly four years ago i remember on the course i was told to only comment on the vehicle in the test bay. So im interested to hear what you all think. Did i do the right thing.
