I've not idea why you would want to report it. st happens, you dealt with it well and without incident. Move on!

Brake system failures are very rare, and can happen at anytime, even if the car was "professionally" checked yesterday it doesn't mean that it's ok today. So, drive with care and attention (which it sounds like you did) and deal with it (which you did) ;-)

I'm pretty sure the Vectra C has a split brake system, but I lost almost all of my braking force, took a good 5 or 6 pumps to regain even a fraction of the required brake force.
Unluck! Good experiment though, I've learned something today

Depends on the car I think.
If the OP's car is as in his profile, it will have a split system. Thus a complete failure in a short time shouldn't be possible with a single leak.

I know that you know your stuff but I disagree, this was a rubber flexi and according to the OP has visible cracking which presuming was accessible to the tester, should've been picked up during the test two weeks ago.

I agree! it SHOULD have been picked up but wasn't. So what do you want to do about it? Maybe make someone loose their job/lively hood /reputation? Mistakes happen, if those mistakes cause death/injury well, ok, it's serious, but in this case they didn't. It's already too easy to just blame everyone else. IMO, as the car driver, you have the absolute responsibility to maintain your car, not the man in the MOT station....

I thought cars now a days had a split braking system,where as if one side had a failed brake line then the brakes would work diagonally?
Depends on the car I think.
All cars have a split system, and have done for years.
Doesn't have to be diagonal, but I'd be surprised if anything other than kits/supercars/specials which use an adjustable bias bar are not.

It was two months not two weeks.

Plenty of time for a mud covered hose to degrade a little further

op was it a rubber flexi pipe or a metal pipe. If its a rear ones the routing goes above subframes/suspension so can be hidden so wont be picked up via mot.

Ive had a few brake pipes pop on the brake rolling test after the rest is checked. Most people never use the full power behind a braking system until mot time when the increased pressure will pop a rusty brake pipe.

Vectra are very common for going around the suspension area done loads in my short time 6 years as a mechanic.

Aren't the rear brake lines the ones that go above the fuel tank or something so that it is blocked from view?
This is exactly what happened to me in a 1996 Mondeo some years back. They'd corroded through and the first I knew about it was piling up to a junction off the M42 on a Friday night in rush hour and my foot going straight to the floor but offering no braking assistance. Scary as Hell.

Anyway, my mechanic took a look and explained why the MOT tester couldn't see it. I certainly didn't go looking for someone to blame. Old cars rot away.

And as I mentioned earlier, on which no one has commented, what about that big red "brake warning" light on the dashboard?

When the proportioning valve failed on my motor the pedal went to the floor as the fluid was ejected from the system, but the light did not come on as fluid was only lost under pressure. I would imaging that fluid was lost when he pressed on the brakes and the hose burst, so the fluid level was not low until the point where he had to pump the brakes.

The daft thing about dual circuit brakes is that the pressure equalisation in the master cylinder means that a total loss of pressure in one circuit will let the pedal travel to the floor anyway.

Picked the car up yesterday morning, the mechanic doing the work even advised us to seek legal advice as the vehicle was not in a roadworthy condition... the front to rear lines snapped in about 5 places just while he tried to remove them! Said I was lucky to not crash it!
Pretty sure the garage sold us a dodgy one, the lines were visibly f****d!

Managed to blow both back brake lines simultaneously too, so irrespective of a symmetrical split system the whole thing drained!

I'm not sure how much conversation you can now have with VOSA / the original dealer now that someone has worked on it...

But yes, sounds like you were sold a lemon. How old is the car?

The failure criteria for a metal brake pipe is something along the lines of 'reduced in thickness by a third'. There is no VOSA approved measuring device for this so without cutting the pipe to measure it the tester has to rely on the good old Mk1 eyeball. Should have covered his arse with an advisory though..

Confused me as it came back as no advisories, been told that even with a check by eye the lines were in need of repair.

Worst luck OP, hope the Vectra gives good service for a while now. I guess some MOT testers have off days, and some aren't thorough enough.

I don't think you can beat a decent service in addition to an MOT, if you can find a decent garage (hard to know which ones are or aren't in my experience, one or two recommendations are no guarantee of a good job in my experience). With a full service by someone doing the job properly as per the manufacturers service sheet, a decent check of suspension, steering brakes etc. should be done, and should go further than an MOT - the wheels come off for a start, allowing a much better check of brake and suspension components, as the mechanic can get their head in the wheelarches and have a good sniff around for any issues.

I will have to agree on that yes

I swear that when my wife had a Vauxhall company car from new, it aged quicker than the dog.
At 4 years Bonnie dog was in her prime, the Vectra however was ready for the scrappy hehe

Be interested to know if the selling dealership was the same outfit which completed the MoT test.

Dozen years ago, whilst watching my TomCat 220 Turbo being tested, with the front wheels on the rollers and the tester's foot hard on the brake pedal, ( looking for "pedal creep" ) his assistant standing near the nearside front wheel was suddenly sprayed with brake fluid. The previous owner according to the various Invoices in the wodge of history which came with the car, showed both front brake lines had been replaced with braided items. It was the braided item which had burst under the "pedal creep" test.

I replaced both front braided lines with solid steel and rubber original ones.

For legal reasons the garage is a separate company to the sales, but all the profits end up in the same persons pocket!

And the way I see it, if it doesn't have a TUV pass then it aint' going on my car!
