Assignment 5: How to perform a Front Disc Brake Job

Which of the following is NOT listed as a specialized tool or consumable needed for replacing brake pads and rotors?

• Brake piston compressor

• Copper anti-seize lubricant

• Impact wrench

• Threadlocker blue

What type of brake pads and rotors does the video recommend for street use, and why?

• Semi-metallic pads and drilled/slotted rotors for maximum stopping power.

• Ceramic pads and blank rotors for less dust and longer pad life.

• Organic pads and blank rotors for a softer pedal feel.

• Ceramic pads and drilled/slotted rotors for better heat dissipation.

What is the primary purpose of chocking the rear wheels and cracking the lug nuts before lifting the car?

• To prevent the car from rolling and make lug nut removal easier.

• To ensure the car is perfectly level for brake fluid drainage.

• To lubricate the lug nuts for future removal.

• To check the tire pressure before starting the job.

When lifting a car with a jack and jack stands, where should the jack stands be placed to ensure safety?

• Directly under the floorboard of the car.

• Under a thick piece of metal frame, avoiding the floorboard.

• On the tires themselves for maximum stability.

• Anywhere convenient, as long as the car is off the ground.

What is the primary reason for sanding and cleaning the hub surface before installing a new brake rotor?

• To prevent rust from forming on the new rotor.

• To ensure the new rotor mounts flush against the hub.

• To remove old brake dust and debris.

• To prepare the surface for painting.

Why is it important to clean new brake rotors with brake cleaner and a paper towel before installation?

• To remove the protective oily film that prevents rust during storage.

• To ensure the rotor is perfectly smooth for optimal braking.

• To remove any manufacturing debris from the surface.

• To prepare the rotor for painting or coating.

Before compressing a caliper piston, why is it recommended to clean the piston and surrounding area, and to avoid spraying brake cleaner directly onto the rubber seal?

• To prevent brake fluid from leaking out during compression.

• To ensure the piston compresses smoothly without resistance.

• To avoid contaminating the brake fluid and damaging the rubber seals with acidic brake dust or brake cleaner.

• To make it easier to install the new, thicker brake pads.

What type of lubricant should be used on caliper guide pins, and why is it important to avoid petroleum-based lubricants?

• Copper anti-seize; petroleum-based lubricants can cause the pins to seize.

• Silicone paste; petroleum-based lubricants can degrade the rubber components.

• Graphite grease; petroleum-based lubricants are not heat resistant enough.

• Wheel bearing grease; petroleum-based lubricants can attract too much dirt.
