Hello, I'm Lee from Kookmin university's racing team in south Korea.
We are gonna participate in 2015 FSAE in Michigan. I have a question for 4 piston calipers.
Our team has used 2 piston calipers for front but, this year, we will use 4 piston caliper from APracing for front upright. The problem is the heat that causes the boiling of brake fluid(Motul DOT5.1). So, we mounted rotor surface temperature sensors. After driving 5 laps in endurance track, rotor temperature rises to 400 degrees.
Actually, there was no problem with 2piston calipers
We didn't have any wings for front and rear.
How do you guys overcome the heat from 4piston calipers? Several teams mount air duct for calipers.
I look forward to get you guys reply. Thank you.
