Time for a bit more of an update having had a fantastic first trackday in the RS at Goodwood yesterday...
All is (almost) well in RS land, it does exactly what it says on the tin...hilarious fun on track, really heavily rear biased giving some genuine LOL moments with epic power oversteer moments. The oversteer also comes on turn in with just a little maintenance throttle. How much angle you want is directly related to how much throttle you give.
I say almost as the brakes didn't seem to hold up to Ford's bold original claim that they could "withstand 30 minutes of hard track use". They were going well all day, you only get 15 miuntes at a time at Goodwood, which in reality is more like 13 minutes, and with an out lap and cool down lap that's circa 9 minutes of full on driving, nowhere near the 30 minutes they claim.
As I know Goodwood like the back of my hand I was seeing what the RS could do and the brakes just absorbed whatever I could throw at them, the pedal stayed firm, required pressure stayed constant, in short, they were epic. That is until
@Sir_Dave jumped in for a ride...
We were talking about just how good the brakes were when I suddenly had that sickening sense through the pedal that something was grinding. Pads worn down? Unlikely...this is what they looked like two ago as I went into full-on detail mode giving the car a thorough detail clean...
So I called it a day for that session, let them cool a little, visually inspected them, had a test drive around the paddock to see if it might just be pad deposits (there was still visible material on the outer pads on all four corners) but no. Time to end the day at about 1530.
Then off I went to have new tyres fitted this morning as three of the four had done 15.5k miles (the other was almost brand new following a recent puncture and being the back right had done next to bugger all work at Goodwood) and although the other three still had life left in them I wanted balanced new rubber all round...
While it was in I asked if I could take a look at the brakes. "No sir, health and safety and all that" came the response so I sat down thinking I'd need to get it up on stands at home this afternoon to see what was up as I still had the grinding.
Then 30 minutes later I hear "Mr Briggs...err, umm, you might want to come and have a look at this"...
The pad material crumbling wasn't a suprise, I've had that many times before on many different pads, nor was all of the paint on the backing plates and hubs having been completely burned off...but this was...
Not only do that pads seem to have worn unevenly (the lower outer piston in the first picture has managed to get the backing plate itself quite worn but on the inside the top most piston seems to have done more work)...in the bottom picture it looks like I've actually bent the pad backing plates!
I've no idea what's gone wrong but the pressure balance across the pistons seems to go to s**t as soon as things get, ahem, a little heat in them. It had the tyre fitters chuckling LOL
Lesson learned from all this, and given how much material was left on my tyres and how little remained on my brakes, is do less braking and more sliding...like this...
There's a lot more of that coming soon but I have a film of me driving my buddy's Fiesta ST and him driving my RS to edit and upload first. For now though...I have some brakes to sort... ???
