Brake Booster Inspection

1. Have an assistant depress the brake pedal with a 98 N (10 kgf, 22 lbf) and 294 N (30 kgf, 66 lbf) of pressure measuring with a commercially available pressure gauge (A).

1. The following pressures should be observed at the pressure gauges in each vacuum.
   Except KQ model

   Vacuum booster Vacuum kPa (mmHg, in.Hg) | Brake pedal pressure N (kgf, lbf) | Master cylinder oil pressure kPa (kgf/cm 2 , psi)
   --- | --- | ---
   0 (0, 0) | 98 (10, 22) | 0 (0, 0)
   294 (30, 66) | 1,539 (15.7, 223)
   66.7 (500, 19.7) | 98 (10, 22) | 4,988 (50.9, 723)
   294 (30, 66) | 9,055 (92.3, 1,313)

   KQ model

   Vacuum booster Vacuum kPa (mmHg, in.Hg) | Brake pedal pressure N (kgf, lbf) | Master cylinder oil pressure kPa (kgf/cm 2 , psi)
   --- | --- | ---
   0 (0, 0) | 98 (10, 22) | 0 (0, 0)
   294 (30, 66) | 1,754 (17.9, 254)
   66.7 (500, 19.7) | 98 (10, 22) | 6,399 (65.3, 928)
   294 (30, 66) | 11,809 (120.4, 1,713)

1. Inspect the master cylinder for leaks if the readings do not fall within the limits shown above.
