Could have been a lot worse. IIRC they came out of the post-accident pit stop around 1m50 down on the leaders, if Johnny Mac had been a little slower getting the car out of the wall they would have been a lap down and heading for 20th.Bull wrote:Bit of bad luck for SVG, made a lot of ground at the end though to end up 6th I think? Would of been interesting if there was rain and/or another safety for him.
I'd say there was more to it then that. It locked the rears up and backed into the wall, if you have no brake pressure you won't get a lock up, and from experience with working on cars when you pump up the brakes the fronts are the first to get pressure due to the way Brake bias/proportioning valves workObsc3ne wrote: David Besnard crash was really odd, no brake pressure into T2 because he didn't pump the brakes after the pad change because he wasn't told to.......are you serious? He's been in this championship (at least in a co-driver role) for ~10 years!
They only change the front pads.. Rears still have pressure, don't need to be pumped...Bull wrote:I'd say there was more to it then that.

Yes, but if you have no pressure on the front, you wont have pressure at the rear. The valves don't open to allow the set % of pressure to flow to the back until the set % has been reached at the front - the front pressure is what opens the valve to allow pressure to the rear.Bold wrote:They only change the front pads..

You hear his interview afterwards? he pretty much admitted it was his fault (he tried to lay some blame on the team), he mentioned something about no brakes until far too late. tbh if I knew I was going to hit a wall that quick I'd rather lock the rears that lock the fronts, not saying thats the case, but you know epic fail whatever the full story isBull wrote:I'd say there was more to it then that.

Yeah, made quite a nice footage of the fire engulfing almost the whole width of the track too. Best thing for a Ford to be honest.Obsc3ne wrote:You hear his interview afterwards? he pretty much admitted it was his fault (he tried to lay some blame on the team), he mentioned something about no brakes until far too late. tbh if I knew I was going to hit a wall that quick I'd rather lock the rears that lock the fronts, not saying thats the case, but you know epic fail whatever the full story isBull wrote:I'd say there was more to it then that.

Just because it is Bull I though I would jump in here. I don't want to start a huge argument, actually that would be kind of fun , but I know that on race cars, well Porsches anyway they run dual or tandem master cylinders, one for the front and one for the rear. Then a balance bar is used to adjust the brake bias, or valves of some sort. This means that the rears would still have pressure and would take the full pedal pressure.Bull wrote:Yes, but if you have no pressure on the front, you wont have pressure at the rear.

Maybe you could say they locked up due to already being hot/bedded in, but pressure isn't the cause.
I'm sure I've read somewhere the V8 Supercars use a twin master cylinder system.Rasmo wrote:Just because it is Bull I though I would jump in here.

they sure did and looking at how they were running, their strategy suggested that they were going to make it on 1 less fuel stop, sadly Bessy's brain fade and Moff's broken g'box put pay to the hay they were making...sure they weren't going to win it, but they were heading well inside the top 10Obsc3ne wrote:Also, both DJR cars looked awesome
Yup. Before the 2nd-last SC the Moffat / Halliday car was running between the Kelly and 888 cars back in around 15th, but they were the leading three cars to have done an earlier short stint which meant one extra mid race pit stop but one less pit stop in the last hour. Unfortunately SC timing made this the wrong strategy to be on anyway ...bradc wrote:... they sure did and looking at how they were running, their strategy suggested that they were going to make it on 1 less fuel stop, sadly Bessy's brain fade and Moff's broken g'box put pay to the hay they were making...sure they weren't going to win it, but they were heading well inside the top 10
