After getting home from an HPDE track day, I noticed this fluid on the lower part of my driver's side front caliper.
It is very sticky, so part of me wants to say it's more of a 'grease' but then it really seems like it was coming from possibly one of the caliper pistons. Notice it is also on the bottom edge of the brake pad. Brake fluid level is ok, but this concerned me a little -
Anyone else with this issue? And word is, GM put dot3 fluid in these cars, has anyone switched to Dot 4/5?
