Looking for some suggestions on what could be causing my left front brake caliper to be smoking after each session on track today to Carolina Motorsports Park.
I have never had this kind of issue previously. The front G-Loc R16 pads I started the day with had about 5-6mm this morning. After both of the first two sessions I could smell something like burning rubber each time when I came off track, and there was significant smoke coming from the caliper area on the left front wheel. I removed the wheel after the first session and there was a piece of rubber on top of the caliper that had just about turned into coal and it just crumbled when I picked it up. I cleaned up the brakes and thought that was the issue. After the second session I had the same smoking and rubber smell. I pulled the brake pads out and could not find any issues. The pads still had 4.5mm remaining.
I decided out of an abundance of caution to install new brake pads. I cleaned up both front calipers and rotors and installed new G-Loc R16 pads. After the next session with the new pads I still had some of the burning rubber smell and a small amount of smoke. It was nowhere near as bad as the first two sessions, but still smoking.
There is no evidence of any leaks or anything rubbing in the wheel well. The only thing I can think is maybe the brake caliper is sticking and dragging on the rotor. I used an infrared temp sensor and the front left rotor was 700 degrees Fahrenheit when I got back to the paddock after the session with the new pads, and the right front was 650. So the left front was as a little hotter, but not significantly. Both calipers were about 450.
Does anyone have any ideas what could be the issue?
