A5: Car and Light Truck Brakes
Automotive Video’s ASE test prep videos have everything technicians need to know to be ASE Certified. Presented by instructor Mark DeKoster this program is a complete A-Z for brakes service and will be a great training experience for any new tech doing brake jobs or techs studying for the ASE A5 brakes certification. A5 addresses the symptoms and causes of the extensive hydraulic braking systems, drum brake, disc brake, parking brake, power assist unit and anti-lock brake system diagnostic information. The program also covers repair information, detailed assembly, cleaning, inspection, and adjustment procedures.
Technicians seeking ASE certification will benefit from the valuable preparation offered by this test preparation video. It features the most up-to-date ASE task list, along with practice test questions like those typically seen on an ASE certification exam to help users feel more comfortable and prepared to pass the actual test. Comprehensive coverage includes overviews of each task list topic, plus ASE test taking strategies and detailed explanations.
Take the quizzes to find out if you are ready to ace the A5.You are expected to have skills diagnosing problems or failures in the following areas: |
 #1 – Hydraulic System Diagnosis and Repair
Your goal to pass: 70% Hydraulic brake system service includes diagnosing and correcting problems that relate to brake fluid condition and level, master cylinder operation, brake warning lamp circuit, brake fluid lines and hoses, and the hydraulic control valves that regulate system pressure. These services, as well as bleeding air from the hydraulic system, are discussed in this chapter. |
 #2 – Drum Brake Diagnosis and Repair
Your goal to pass: 70% Proper diagnosis and repair of these systems begins with a road test. Diagnostics of poor stopping, pulling, dragging, or incorrect pedal travel caused by drum brake hydraulic problems; determine needed repairs are all covered in this section. |
 #3 – Disc Brake Diagnosis and Repair
Your goal to pass: 70% There are three main categories of disc brake service: pad replacement, caliper overhaul, and rotor machining or replacement. Technicians should be able to diagnose poor stopping, pulling, dragging, or incorrect pedal travel caused by disc brake hydraulic problems and determine needed repairs. |
 #4 – Power Assist Units Diagnosis and Repair
Your goal to pass: 70% Most late-model vehicles use a vacuum booster to help apply the brakes. Technicians will be expected to be competent in testing pedal free travel with and without engine running to check power booster operation, inspecting the vacuum‑type power booster unit for vacuum leaks and proper operation, inspection of the check valve for proper operation and repair, adjust, or replace parts as necessary. Inspection and testing of the hydro‑boost system and accumulator for leaks and proper operation and the repair or replacement of parts as necessary are also covered in this section. |
 #5 – Miscellaneous Systems Diagnosis and Repair
Your goal to pass: 70% When diagnosing brake problems or servicing brakes, it is important to consider all the components that can contribute to brake performance deficiencies. Technicians should be able to diagnose wheel bearing noises, wheel shim and vibration problems in order to perform needed repairs. Checking the parking brake system; inspect cables and parts for wear, rust, and corrosion; clean or replace parts as necessary; lubricate assembly is also covered in this section. |
 #6 – Electronic Brake Control Systems – ABS,TCS, ESC Diagnosis and Repair
Your goal to pass: 70% Troubleshooting antilock brake problems can sometimes be done without referring to service literature, more often, it requires detailed diagnostic charts and or a scan tool to access the onboard diagnostic programs, as well as for performing service procedures such as system bleeding. wiring diagrams found in shop manuals.Technicians are expected to be able to diagnose poor stopping, wheel lock up, false activation, pedal feel and travel, pedal pulsation, and noise concerns associated with the electronic brake control system in order to determine needed repairs. |
