And now for some actual non-G progress. And not pertaining to a lame house! It's time to get cracking on the race car! As some may know, I've been chasing an inconsistent brake pedal for some time now. After about 3 laps the car gets sketchy. I used to pad certain brake zones and just live with it, but the competition has stepped up forcing me to as well. I tried a couple different iterations of better sealed brake ducting with no change. Eliminated rear knock back in 2 phases with no change. Went up 1 in front brake compound with no change. Tried a firmer brake fluid that was firmer for 3 laps then the same old same old. Upgraded from C5 to stiffer C6 calipers to no avail. Upgraded from Camaro hubs to C7 SKF x tracker hubs to no avail.
Time for the Stoptechs. I had to pull my pants down and unload over $1100 for these 2 piece rotors last year to play with the calipers I already had. The rotors showed up the day I went to the track for practice, the Friday leading into the race weekend. Ended up being a moot point as the caliper pistons were trashed.
The other 4 were worse. Maybe I would have been OK? But there's very little send left with my approach to setting up and equipping this car. Thanks to my friend who's been learning from a pro, there's nothing I can leave on the table. Here you can see the newer pistons are more thoughtfully designed. I'm genuinely curious as to what's up with the inner surface of the piston. The diameter being cast in is an excellent detail. An old piston is pictured in the bottom for clarification.
One or both of the calipers was leaking and I got them for basically free with new seal kits. I traded tires I won for them. The old seals didn't look hammered, but the dust boots were gone.
While they are radial mounted 4 pot calipers, they're not true racing calipers. I wonder if I should have left the boots off. I bet they're roached within a season.
Rebuilding was easy peasy though. My compressor died so I couldn't split the hubs from the adapters to relocate the spindle cooling duct shrouds. I'll swing by the hangar tomorrow and handle that to mock it all up and see what I'm missing. While this brake kit is a bolt on when you buy it from Stoptech, I've tried to piecemeal it together on the cheap with moderate success. I anticipate a couple issues I don't see just yet, but that's why I do this now and not the weekend before the first race.
