BRAKES FAILED !!!! CORSA 04

Sounds like the brake fluid might have vapourised? Had she been braking lots? I wonder if water had got into the brake fluid somehow? (see "a little knowledge" thread).

If it is not operator error , then the only thing that can cause this to actually occur and then cure itself is master cylinder failure, but this is very unlikely on such a new vehicle. Assuming it did occur and there are no major fluid losses then get a new master cylinder fitted. On such a new vehicle it should still be under warranty.

Take it back to the dealer and get them to check it over. Asking in here isn't the best course of action with such a serious fault.

The message from "mederb" contains these words:

I know people who can get through a set of pads in less time than that!

However, take it to the dealer and get it fixed. Should still be under warranty, yes?

Failed front wheel bearing?

Had she been driving with the handbrake on? Seen it before where either sticking brakes or driving with the handbrake on has boiled the fluid thus giving no pressure. Stop for a couple of minutes, brake fluid cools and it works again.

Me for a start.

Care to explain that? I can't see the connection especially as there was no braking at all.

The disc wobbles about in the calliper, pushing the pads back. Application of the brake pedal pushes the pads back out, but the pedal reaches the floor before that happens. If you've ever changed a set of pads and driven off without pumping the pedal first, you will have experienced this exciting moment :-)

Pushing the pedal a couple of times brings the pads back out into contact with disc and all seems well until after the next couple of corners...

Often when a front wheel bearing first develops excessive play, as opposed to becoming noisy, the first sign will be that sometimes the brake pedal travel is longer than normal. This is often mistaken for a braking system fault.

For the pedal to go to the floor, the bearing wear has to be extreme so this may not be causing the OP's problem. It is so easy to check that it is worth a try though.

HTH

Air in the pipes?? Any work done recently?? Sabotage?? Any signs of fluid where it shouldn't be??

Overheating hub boils the brake fluid which then means no brakes until it has cooled down.

Could be one circuit failed, pumping the pedal moves the tandem piston so the other circuit will still work. Get it towed to a garage or have a mechanic come out and look at it.
