guys, on my 57 i am running a disc brake conversion that uses 1970-78 camaro rotors, calipers and bearings on my factory spindles. brakes fine and drives fine, with no pulling at speed and no pulling when braking. me, always wanting to make sure everything is fine, i took my infrared temp sensor today after getting home from driving and checked both front rotors. drivers side was about 40 degrees hotter than the p***engers side, like 120 vs. 160 degrees, if i remember correctly. jacked up the front and both wheels spin equally as hard. i noticed the rotors looked a little blueish, heated, so that caught my attention, but when i looked at my daily drivers, a 2003 s-10 and a 1990 full size k-1500 4x4, both of those trucks also show a blueish tint on the rotors. i run ceramic pads on all my trucks to keep the brake dust down. so, do ceramic pads tend to run hotter and can make the rotors look heated, and is a 40 degree temp difference a problem from one rotor to the other ? i checked the bearings about a year ago, or about 100 miles ago, and everything looked fine. thanks guys. leonard
Ceramic brake pads typically have lower friction coefficients, and act as an insulator - raising rotor temperatures in cast-iron disc systems.
the only thing that returns a caliper is just the release of fluid so the reason for diferent temps is one isn't sliding as easily check the slides and hardware.
thanks for the info guys...... when i checked them on my 57 the truck sat maybe 5 minutes, due to me having to look for my temp sensor.... i decided to take the sensor along with me to my friends house and check them on my full size 4x4. right after pulling up to his house i had one at 200* and the other at 300*......... 100* difference... so, i am not gonna worry about it for now. also a buddy told me the blueish coloring is normal..... thanks again for the info, i appreciate it. leonard
Check Performance Frictions website for info and consider getting a set of temp paints or temp stickers to get accurate readings
