Snetterton 3/5/19 brake fail:-)
Discussion
A touch of amusement for you all.
Today I did a trackday at Snetterton with my Son, in our trusty little Clio 172. First run out there, Lee was driving & at the end of the Senna straight @ 105mph the rear caliper decided to eject the pads. No accident, nobody hurt, no harm done, we are still laughing, it could have ended differently !! **** some colourful language at the end be warned **

Should never happen in a perfect world but all good if we walk away Wh00sher said:
Why did the pad come out??
New pads fitted, all went back together nicely. We are pretty sure the little spring clips holding the locking sliders had become weak / brittle & disintegrated, vibration caused the sliders to move, pads gone !In my 40+ years of driving & playing with cars, I have never had this happen, lesson to be learnt, replace the "fitting kit" too (yes we have now).
Mine was very different in that respect.
The pads were right down to the metal on one only, as I went a bit further into the metal there was enough space for the piston to come past its seal ring & out came the fluid when I next braked.
The REALLY strange thing was no perception of lack of braking performance or increase in noise when I went onto the backing plate of the pad.

Hopefully not much harm done for you when it went. It's easy to nitpick with hindsight but I guess that goes for everything with the track cars, usually old & replacing everything just isn't practical.The pads were right down to the metal on one only, as I went a bit further into the metal there was enough space for the piston to come past its seal ring & out came the fluid when I next braked.

We have only had the car a short time, new to tracks & yesterday was only our second meet, so I'm putting it down to teething problems, some of the guys there had far better equipment but little experience of spirited driving, but it's not a race, who cares.

No harm done apart from underpants, just (also) inexperience at the time & not doing enough checks when on track & in "accelerated wear" circumstances & EBC sh!t pads didn't help.
All good then. After that, our day was excellent, luckily the round trip to Euro Norwich is only an hour, so I did the road run & Lee ripped it al apart in preparation. Unfortunately the bikers didn't all have a great day, at least 4 dismounted at speed & we heard on had been hurt. The bikes un-nerved me & I was only watching - serious speeds :-oAnother one to watch is when you put new brake pads in, especially pads with a more abrasive compound, but are running with brake fluid that is not fresh.
I did this in preparation for a Hullavington track day, and lost all braking as I braked hard for the 90 left onto the main runway at 120 mph. Brake fluid had boiled.
Good job it was a wide runway and I was wearing waterproof undercrackers. I had taken the old pads with me, so swapped them back in, topped up the fluid and all was fine for the rest of the day.
