For normal use of SBS Racing brake pads, it is recommended for all references to change for new brake pads when approximately 2.0 mm of the friction material remains. On circuits with heavy mechanical and thermal load on the brake system and brake pads, it may be an advantage to replace the brake pads earlier to reduce the above described bad habits such as front wheel drag and warped backing plates. On extreme hard braking circuits, we have with great success tested the following minimum thicknesses for brake pads in Racing & High-Performance brake systems:
GP MOTO2 / RED BULL RING / BREMBO: SBS 845 th = 9.6 mm new, change at 7.0 mm, min friction material th = 3.0 mm
WORLD SBK & BSB / IMOLA & DONINGTON / BREMBO: SBS 889 th = 9.5 mm new, change at 7.5 mm, min friction material th = 2.5 mm
BRAKE SYSTEM TEMPERATURES
To be able to identify brake problems or issues experienced from brake performance, it can be a good idea to know in which pressure and temperature range the brake system works on the various circuits. Data logging is used in many championships, in which logging of brake pressure front and rear is becoming standard. Temperature measurement of brake discs, brake pads and calipers with IR or thermocouple sensors, as well as position and travel of brake lever with potentiometer sensor is possible, but not as commonly used as logging of pressure due to class technical rules limiting the number of channels. Many teams use so-called temperature sensitive paint on the outer diameter of the brake discs to indicate in which temperature range the brake pads and brake discs work.
To indicate the temperature range of the brake caliper and brake fluid, self-adhesive temperature stickers can be used on the brake calipers. The most used sticker range is: 88- 127 o C and 132-171 o C. At LeMans and BoldÓr 24 Hours, SBS Racing Service has used 204-260 o C for OEM standard calipers while testing new compounds in Superstock category.
Thermal paint kit is available with the following temperature rate:
GREEN > change to WHITE at 430 o C ORANGE > change to YELLOW at 560 o C RED > change to WHITE at 610 o C
Brake disc prepared with Thermal Paint GREEN (430 o C) and ORANGE (560 o C).
Brake caliper prepared with temperature stickers.
