Brake Jobs
This should be done before servicing a brake system with an electronic park brake.
What is put the vehicle into brake service mode?
The component that monitors individual wheel rotation for the ABS system.
What is the Wheel Speed sensor?
This component serves as the mounting service for drum brake components.
What is the drum brake backing plate?
What is the vacuum booster?
The amount of pressure that typical brake lines should be able to withstand.
What is 8000psi
Technician A states that you should always top off a master cylinder when it is lower than the max line. Technician B states that if you are doing a brake job you should make sure the master cylinder isn't at the max line. Who is correct?
Tech B
The amount of times that ABS can cycle brake pressure during operation.
What is 15 times?
The ABS module contains this component to produce brake pressure separate from pedal application.
What is an internal pump?
What is excessive rear rotor runout?
The two primary materials that are acceptable for brake line construction.
What is steel and nickel-copper?
The action that must be taken during a brake job if a vehicle has a mechanical integral caliper parkng brake.
What is screw the piston in to depress it?
This happens during the ABS pressure-hold phase.
What is, No additional pressure reaches the brake?
This component delays front disc brake application until pressure has built in the rear drum brakes.
What is the metering vavle?
Technician A states that the red brake warning light indicates a problem with the anti-lock brake system. Technician B states that the red brake warning light only indicates a base hydraulic braking concern, who is correct?
Tech B
What is two?
It is normal to hear some brake noise when performing this action in the vehicle.
What is braking in reverse?
This happens during the ABS pressure-release phase.
What is, Braking pressure is released so that the wheel can spin?
The 3 common types of power brake assist.
What are, Vacuum, Hydraulic, and Electronic?
What is a vacuum pump?
This can happen if the brake fluid becomes contaminated with any petroleum based product.
What is rubber components swelling?
The 4 primary surfaces you should be sure to clean during a typical brake job.
This happens during the ABS pressure-apply phase.
What is, the motor runs to reapply braking pressure?
These 4 components are what compromise a basic ABS system.
What are, wheel speed sensors, ECU, ABS warning light, and hydraulic modulator assembly/HCU
These 4 conditions can cause unwanted ABS self-activation.
What is Tire circumference or wear issues, Loose wheel bearings, sensor gap problems, or glazed brake pads or shoes?
The 4 types of brake bleeding that can be performed.
What are, manual, vacuum, pressure, and gravity bleeding?
