My brakes failed while driving !
Something really worrying happened this morning.
Whilst driving to work was coming up to some traffic lights that went red suddenly.
Was doing approx 45mph and hit the brakes approx 5 car lengths from the red light Stop line .
Instead of braking as I would expect it felt as if ABS had kicked in (rough feeling under the pedal) from the moment I hit the brake aalthough I kept the pedal depressed the car hardly braked and I had to pull up the handbrake to assist with stopping !! Ended up 2 car lengths over the stop line ......
On way home I waited for a clear stretch on the road and hit 60mph and slammed on the anchors ... It braked exactly as it should have done without any dramas and ABS did what it was supposed too. Did this several times and it was fine .
Very worrying and will take it to a garage .. anyone experienced something similar or know what it could be

That sounds worring indeed.
Other than a leak on the brakelines/abs lines etc try checking the brake master cylinder as sometimes the piston might seize or corrode inside.
Fingers crossed it will not be expensive if something needs to be fixed

Really warm spell following lots of rain = slippery road surfaces. I take it no ABS warning lights on the dash?

In response to some of the posts.....
It was dry and mild
No oil on the road
Would have made it through the lights normally but there was a traffic light camera . In all fairness if I carried on without braking I wouldn't have got flashed but didn't wanna risk it .
Also no ABS light came on . Convinced ABS didn't come on and will get a local garage to check cylinder , lines and brake oil etc
Tyres are new 1200miles on Bridgestone Potenza Adrenalin RE002 on all 4 corners

Interestingly, I had this a few times on cars and bikes and usually after some spirited driving OR a potholed road !
If you ever get the feeling that when you brake sometimes its pulls left or right slightly and yet the next time you brake all is even with no bias to the side then its possible that the brake piston has retracted slightly allowing the pad to have more clearance to the disk.
When you depress the brake pedal the slight difference gives you a "longer pedal" and if you pump the pedal once all is restored to normal.
Apparently, with our rougher roads
and no maintenance being done by the councils still, this can happen if you drop into a big / series of holes.
I am not sure of the dynamics of why this happens but the race boys can have this problem too and I am sure one of them will be along to give the techy reasons soon
