So yesterday I was driving along in M'cr city centre and I could feel the brakes becoming spongey.. Cue alarm bells in my head! Anyway, drove on with caution and the intention of bleeding the brake system myself when I got back to my house.
A minute later at the next traffic light I put my foot on the brakes and the pedal went straight to the floor, no brakes whatsoever! Just about managed to stop it using the handbrake and pumping the pedal to get a small amount of pressure back in them and bailed it into a side road where I got it recovered. Turns out the brake lines to the back wheels split and it pee'd all the fluid onto the tarmac.

Got it recovered to a Vauxhall main dealer who are doing the job for me now, at great expense, so that I can catch my ferry tomorrow morning..

Anyway, the reason for this post is that it was MOT'd by the garage I bought it from only 2 months ago... anyone know where I stand with this as the lines are visibly knackered, just by looking underneath the car you can see the rubber lines perishing and cracking. Surely it shouldn't have passed the MOT if the lines were in that bad condition?!

It certainly shouldn't have passed if the lines are in such bad condition. Get the dealer's MOT tester to have a look at them, if he thinks they could have been in an unfit condition at the time of the MOT you can raise it with VOSA.

If it's just a random part failure then there's no reason the seller should be liable, the MOT can only test the condition at the time it was presented.

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?

They may get into trouble with vosa if they missed an obvious defect, but they won't be liable for anything as they didn't make the item faulty.

Depends on the car I think.

A tip for the future, if in normal driving you feel the brakes getting spongy something has gone wrong. If airs getting in fluid is getting out.

I would ask the dealer to do a report on the rest of the car.

If there is no fluid left in the system only the cable driven handbrake will work. OP says both sides failed anyway, so all braking was lost.

That sounds very unlucky to say the least ,loosing all the fluid so both sides fail ,as for both hoses being split at exactly the same time even more unlucky.

Scary stuff! How long had you been driving the car for when this happened? You haven't made any enemies recently have you? Just a (slightly Hollywood) thought..

It certainly shocked me! 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.

The MC is divided so that only the upper volume is shared between both circuits, and once the fluid drops below around half way it is kept dividied.

Cars have had split circuits since about 1970 IIRC - certainly way, way back.

Had driven it all the way from my flat in Liverpool, so must have broken on route! When I saw the rate it was losing fluid I was in two minds as to whether it had a helping hand, but garage say it's just an excessively worn part!

You tend to find that the remaining diagonal brakes do work its just that the pedal sinks right down to about the last inch of travel near the floor before you feel any response and you get massively reduced braking effort obvs.

It will be a steel line burst at the back . 28 days from the issue of the test you can go back to Vosa to inspect it . Did the mot have any advisories re brake pipe corrosion ?
Unless the garage are particularly stupid and want Vosa to be notified I would imagine they will replace the parts foc .
Thankfully it's very rare but if we miss something and its picked up we have always put it right at no cost

That's a relief then, at least you can rule that one out!

I always thought brake lines perished from the outside (i.e. rusted where there is moisture and oxygen), rather than the inside, which suggests that it should have been picked up on visual inspection at the recent MOT.

Some systems are split so fluid can only be lost in half the system, either front/back or diagonal corner to corner. Handbrake should be used in conjunction with pumping and engine braking. I had a split pipe on my mx5 on the main line front to back, front brakes still worked, was a pig to bleed after replacing the line though due to air in the ABS unit.

Unfortunately having it repaired means Vosa can't get involved now but you might be able to recover the cost from the garage although they might not want to pay dealer price and now the evidence is in the bin could refuse

Aren't the rear brake lines the ones that go above the fuel tank or something so that it is blocked from view?

Out of interest, how old is the car?

Precisely.

It seems the OP would have us believe there was no big red brake warning light illuminated on the dashboard in front of him.
