  1. Hey everyone, time for an update. The conditions were cloudy and cool on the Saturday of Vintage weekend, but I still lost brakes during the third session. I bled the suspect RH caliper and got back most of my braking. Managed to complete fourth session but pedal travel was increasing. Just to be safe I did a four-wheel bleed before heading home. I tried to do an automated ABS bleed procedure with my newly purchased Autel MaxiCheck Pro but was informed by their tech support that it won’t work on my car. Too bad, so sad. RH brake caliper has been ordered and I’m presently sourcing out stainless steel brake hoses. The RBF660 brake fluid has been in my system for 6 weeks, so that will have to be flushed. How often do you guys do a complete flush on the Fuchs 5.1 and the Total 600? I might just consider going back to DOT 4 now that I’ve convinced myself that I don’t have a boiling brake fluid issue.
  2. @white_cross looks like @Rare Snake has raised the bar a notch or two. I watched Dason's runs on Saturday and I don't think "charming" this snake with a flute will work. You'll need to bring a big club to this snake fight. I always cheer for the underdog and I can't wait to see the completion of project "Snake Charmer"
  3. @Jim Eh. You couldn't have summed it up any better. I am impressed at how quickly our club reacted to the situation and addressed the concerns. A HUGE thank-you to Al for organizing the "tire stack building party" and to all those who helped in stacking, banding, delivering, and setting up the soft barrier at corner 3. And I'm sure I can speak for everyone when I wish Don a speedy recovery.
  4. @helix Any chance we can get the Sunday event uploaded to Axti.me or at least provide a link?
  5. A big thanks to everyone who shared their videos from this event. I always look forward to reviewing and analyzing these videos to see where I can make some improvements or correct some bad habits. Great perspective from the standpoint of what I was seeing on the course compared with what was happening inside the car. Some of the cars that I saw on course that appeared to be navigating the course smoothly were actually being driven at the limit with some ridiculously fast steering inputs and corrections. No wonder these drivers worked up a sweat by the end of the run. Like I said, some of the videos were very instructive while others that showed how to take down an entire wall of cones, or how to mow the grass were certainly entertaining. Looking forward to the next event. Got to get myself a GoPro so I can put together some bloopers. At least that will be one thing I can beat @Magner at.
  6. For events #9 and #10 this weekend, the "Number of Runs" listed on MSR says "Each driver will get 5 runs to count for championship points." So maybe in fairness to those who have already signed up and paid we should not make any last minute changes this weekend? Just my thoughts. Turnout looks pretty decent for both days and the weather also looks good. Should be fun.
  7. Okay, that's just plain crazy. And here I thought you're supposed to rest your clutch foot on the dead pedal while going down the front straight and take some deep breaths and relax before hitting the brakes for corner one. This is the one part of the lap that I find relaxing. The idea of pumping the brakes with my clutch foot and hoping that I will actually have brakes as I reach the braking markers takes away my relaxation moment and changes it to anxiety. Not sure this is in compliance with my doctor's advice when he said … " you should avoid stress". Cool video clip, though. Thanks.
  8. Actually, the RS uses the rear drive unit clutch plates to transfer more torque to the outside wheel, rather than using the more common brake application method. As far as the front brakes being used for torque vectoring, I don't think that's part of the process, so I wouldn't think that is adding any heat to the brakes. Just curious whether the sponginess you experienced at the track stayed the same after several days of city driving. Strangely enough, my pedal would become firm again after driving three days or so. I guess your original question about whether you need to bleed the brakes after every event, even with RBF 600, is "probably". If I come up with a fix, I'll certainly let you know.
  9. Wow!! You brought up some really good points @donrolandofurioso. I think you hit on a couple of points that might be contributing to my problems. In my last post I said I would update and report on the results of using Motul RBF 660 brake fluid. The afternoon temperatures on Saturday (Event #3) reached 30°C so it was a good day to test for high brake temperatures. However, the same pattern repeated itself … great brakes until the last session of the day. Only this time, a LOT of air got into the system and I had to bail out (pedal went 90% to the floor). Got home and gravity bled right front only. Didn't notice any air coming out of outboard pistons but got a lot of air coming out of inboard pistons. Brake pedal feel came back to almost normal. I'm leaning toward air being drawn into the system (fittings? brake hose?) or maybe migrating from the ABS module. I have a hard time believing that the fresh 660 brake fluid was actually boiling. I didn't feel confident returning to the track on Sunday and have the same problem reoccur, so I called it a day. I like your theory about air hiding inside the ABS unit and just waiting to spring out when the ABS cycles and then do their evil deed. I don't recall, one way or the other, whether I triggered an ABS event on my last session, but it's certainly possible. I went down to Vickar Ford and tried to get an explanation on how they flush the system while cycling the ABS module. Apparently it's a time consuming process where they suction out the old fluid, and then pressure-fill and bleed while activating the ABS system. Something like >$350. My car's in the body shop this week after being rear-ended (obviously not due to me stopping short), so I won't take any action until next week. Probably try one more flush procedure before spending $300 -$400 at the dealership. Thanks again for the great input!
  10. Helix, did we ever manage to upload our timing results to Axti.me? Can't find Sunday results for WSCC.
  11. Thanks Helix, for the detailed explanation regarding point #4. Maybe, like someone said earlier, the number of runs should be proportional to the number of entrants. I guess that's why heavily attended events (Nationals) can only offer 3 runs. Maybe we should be happy with four runs if we can maintain a 40 or more entrants for all our events. I think I can speak for everyone when I say "we really appreciate your efforts!"
  12. Great summary of the pros and cons for changing the schedule and number of runs! Can you elaborate on step #4. I'm not sure I understand why it would be unfair or disappointing. I'll still keep my vote for 5 runs with a schedule that opens at 8:30 AM and first run group goes out at 10:00 AM. Thanks Helix ... keep up the good work!
  13. "Anyone can be fast in 10 runs" ? … uh, not really. Believe it or not, between broken asphalt and timing gremlins, I managed to get in 7 runs. Did I improve with each run? - you bet. Was I fast? - nope. Based on my rate of improvement, I would guesstimate it would take me 15 runs to get "fast". Obviously my vote is for the most runs we can squeeze into a day.
  14. Hmm, only one reply to this question? I thought there were a lot of people suggesting changes to our schedule. Anyways, here’s my two cents: I would favour a somewhat compressed schedule with an earlier start time. I like the idea of six runs but would prefer it be split to two sets of three runs. Seems like a long time to be standing in the hot sun for six continuous runs.
  15. Yeah, I also like the sound of squealing tires and the smell of burning rubber and fried clutch plates … but just not on my car. The decision to go with a sharp-turn start was made by consensus last year after receiving complaints of “drag-strip” starts favouring the high HP cars. There was also a concern that these repetitive hard launches would result in accelerated (pun intended) wear on tires and clutches, thereby making Autoslalom less cost friendly. Not to mention snapping a half-shaft totally ruining your day. We had some hard-core competitors circumvent the 90° starts last year by crawling up to within a few feet of the timing lights, come to a stop, and then engage “launch control”. This achieved the desired burnout but did little for the elapsed time. To each their own. Glad to see you’re signed up for the Sunday event and maybe the course designer will come up with a compromise that will allow you to have your cake and smoke it too!
