This is page BR-16 of a factory service manual, presenting Service Data and Specifications (S.D.S.) for the brake system. The General Specifications column lists the front brake as type CL16 with a 45.0 mm (1.772 in) cylinder diameter, 32.0 x 10.0 x 94.0 mm pads, and a 214 mm (8.43 in) rotor outer diameter; the rear brake is type LT18B with a 15.87 mm (5/8 in) cylinder, 25.0 x 4.0 x 172.8 mm linings, and a 180 mm (7.09 in) drum inner diameter. Master cylinder inner diameters are 23.81 mm (15/16) large and 17.46 mm (11/16) small; the brake booster is type M15, and the dual proportioning valve split point is 2,942 kPa (30 kg/cm², 427 psi) x 0.4 reducing ratio. The Inspection and Adjustment column gives brake pedal free height (190-200 mm M/T, 194-204 mm A/T), depressed height (95 mm under 490 N), stop lamp switch clearance (0.3-1 mm), pedal ratio (4.2), check valve and booster maximum vacuum leakage limits, and front disc brake wear limits: 2.0 mm minimum pad thickness, 0.07 mm max rotor runout, 0.02 mm max parallelism, and 11.0 mm minimum rotor thickness.
