Following a misfire code I thought I'd give the old girl (2001 V6) a thrash to see if it would clear.
Went to a quiet road nearby with about a mile of straight between two mini roundabouts - took it up to nearly 5K revs both ways doing heavy braking, obviously, before entering the roundabouts
Strong smell of brake pads! and in about half a mile, attempting a slowdown for a left turn, the brake pedal went straight to the floor!! Overshot the turn and slowed using the Hand brake.
After letting things cool for a about 5 minutes and checking for obvious fluid leaks, It was possible to get a bit of pedal travel by pumping it, then I limped home.
Once cool, brake pedal has improved but is spongy so it looks like a case of brake fluid boil.
I Don't know when the fluid was last changed, I've only had the car 9 months but It is definately getting done before the cars next outing.
There is nothing quite so alarming as a brake pedal going right to the floor and sailing straight on! So my strong advice is DO NOT IGNORE REGULAR BRAKE FLUID CHANGES.
Oh and the misfire "fix" didn't work so a new coil has been ordered
