Piston Cup and Pressure
Cup Inspection (B)		 • Check the brake operation by depressing the brake pedal. Look for damage or signs of fluid leakage. Replace the master cylinder assembly if the pedal does not operate properly or if there is damage or signs of fluid leakage.
• Check the difference in brake pedal stroke between quick and slow braking. Replace the master cylinder if there is a difference in pedal stroke.
Brake Hoses (C) Check for damage or signs of fluid leakage. Replace the brake hose with a new one if it is damaged or leaking.
