Had a proper brown trousers moment in the C3 Pic today, I was driving around fine for a couple of hours and then parked up for about 40 minutes. When I got back in and set off the brakes were almost totally gone, the pedal was really spongey and needed to be pushed to the floor to get any kind of stopping power at all. The brake power was slightly improved if I dipped the clutch and every sof often it would come back which led to some interesting driving on the way home. When parked up if i press the brake repeatedly it provides a bit of resistance but can be pushed to the floor.
I've just had an MOT last week and the front brake pads came up as an advisory but that was it. Any one had a similar experience or have any pointers?
