SERVICE DATA AND SPECIFICATIONS (S.D.S.) — General Specifications

BR-72spec tableUnverified

ABS cars have disc rear brakes (model CL7HG, rear rotor 240 × 7); non-ABS cars have drum rear brakes (model LT18G, drum 180 mm). Master cylinder bore is also larger on ABS cars (20.65 vs 19.05 mm). Source prints '240 x 7 (0.94 x 0.28)' — the imperial pair appears to have lost a digit (should read 9.45 × 0.28 in). Captured verbatim as-printed; flagged in model_notes.
