CELICA'S brake package includes 275mm diameter ventilated disc brakes with piston-eccentric type callipers and 269mm solid rear discs. Four-channel, four-sensor ABS anti-lock brakes with electronic brake force distribution (EBD) are standard on ZR and linked with the safety pack on SX. Toyota claims Celica's stopping distances have been reduced as a result of to the car's reduced weight, improved grip and more efficient braking system. Electronic brake force distribution (EBD) replaces a load-sensing, proportioning and by-pass valve. The EBD control uses the ABS control unit to achieve a more ideal brake force distribution between the front and rear wheels, according to road conditions (available traction) and vehicle load. It allows front and rear braking force to more closely match the ideal curve under all vehicle load conditions. EBD also controls brake forces to the right and left wheels when braking in corners.
