Inspect and Service Brake System and ABS

The purpose of a vacuum brake booster is to :

• Allow the hydraulic fluid to escape

• Force fluid into the brake lines and wheel cylinders

• Prevent the wheels from locking up when the brakes are applied

• Create a greater braking force from minimum pedal effort

Air in the brake hydraulic lines will cause :

• Vibration in the brake pedal during braking

• Spongy brake pedal

• Noisy brake

• Hard brake pedal

The process shown in the figure is :

• Disc rotor thickness measuring

• Disc rotor Installing

• Disc rotor changing

• Disc rotor facing

The figure shows how to measure the brake :

• Pad thickness

• Shoe thickness

• Pad length

• Shoe length

The figure shows how to :

• Install the brake pads

• Remove wheel cylinder

• Disconnect the adjuster

• Disconnect the parking brake cable from the lever

The figure shows a :

• Leading and trailing shoes drum brake

• Two leading shoes drum brake

• Fixed caliper disc brake

• Sliding caliper disc brake

State the type of drum brake shown in the figure

State the type of wheel brake shown in the figure

The figure shows how to measure the brake :

• Disc thickness

• Drum thickness

• Brake drum diameter

• Brake disc diameter

The parking brakes in a passenger car are applied to the :

• Front wheels only

• One wheel only

• Rear wheels only

• All wheels, both front and rear
