Questions: Which of the following is not a factor in determining the effectiveness of a brake system? a. heat dissipation b. lubricant c. pressure d. frictional contact area

Solution Steps

• Consider the elements that directly impact the performance of a brake system.
• Key factors typically include heat dissipation, pressure, and frictional contact area.

• Heat Dissipation: Essential for preventing brake fade and maintaining performance.
• Lubricant: Generally not used in brake systems as it would reduce friction, which is necessary for braking.
• Pressure: Critical for applying force to the brake pads or shoes.
• Frictional Contact Area: Important for maximizing the braking force.

• Evaluate which option does not contribute positively to the effectiveness of a brake system.
• Lubricant is not a factor in determining brake effectiveness as it would hinder the necessary friction.
