CHECK HYDRAULIC BRAKE BOOSTER FLUID PRESSURE CHANGE (a) Check the battery positive (+) voltage. Standard voltage: 10 to 14 V (b) Turn the ignition switch OFF, and depress the brake pedal more than 40 times. HINT: When a pressure in power supply system is released, reaction force becomes light and stroke becomes longer. (c) Install LSPV gauge (SST) and brake pedal effort gauge, and then bleed air. SST:
09709-29018 (d) When operating the hydraulic brake booster and depressing the brake pedal (see table below), check the fluid pressure. Standard fluid pressure: At 245 N (25 kgf, 55 lbf) At 343 N (35 kgf, 77 lbf) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 2,700 kPa (27.5 kgf/cm 2 , 391 psi) or more 0 kPa (0 kgf/cm 2 , 0 psi) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 3,950 kPa (40 kgf/cm 2 , 568 psi) or more 0 kPa (0 kgf/cm 2 , 0 psi) (e) When operating the hydraulic brake booster: (1) Turn the ignition switch ON. Wait until the pump motor has stopped. (2) Depress the brake pedal (see table below) and check the fluid pressure. Standard fluid pressure:
At 49 N (5 kgf, 11 lbf) At 98 N (10 kgf, 22 lbf) At 147 N (15 kgf, 33 lbf) At 196 N (20 kgf, 44 lbf) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 1,618 to 2,795 kPa (16.5 to 28.5 kgf/cm 2 , 234 to 405 psi) 1,716 to 2,893 kPa (17.5 to 29.5 kgf/cm 2 , 249 to 419 psi) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 4,413 to 5,624 kPa (45 to 57 kgf/cm 2 , 639 to 809 psi) 4,609 to 5,786 kPa (47 to 59 kgf/cm 2 , 668 to 839 psi) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 7,208 to 8,436 kPa (73.5 to 85.5 kgf/cm 2 , 1,043 to 1,214 psi) 7,502 to 8,679 kPa (76.5 to 88.5 kgf/cm 2 , 1,088 to 1,259 psi) FRONT BRAKE PRESSURE REAR BRAKE PRESSURE 9,905 to 11,082 kPa (101 to 113 kgf/cm 2 , 1,434 to 1,604 psi) 10,346 to 11,523 kPa (105.5 to 117.5 kgf/cm 2 , 1,501 to 1,671 psi) 2.
CHECK HYDRAULIC BRAKE BOOSTER OPERATION (Using Intelligent Tester) (a) Check the battery positive (+) voltage. Standard voltage: 10 to 14 V (b) Turn the ignition switch OFF, and depress the brake pedal more than 40 times. cardi
