What Did You Learn This Month?
"Night School" would not be complete without a quiz! Don't worry about your test-taking skills or grades. This is an open-magazine, true or false test. Clues can be found within the "Night School" text, photos, and captions. Have a good month!
True or False Questions:
1. Ausco-Lambert brakes were internal disc types with self-energizing ability. Modern disc brakes do not offer this self-energizing feature.
2. Modern disc brakes can be easier to service than drum brakes. A disc front brake pad change can be done without removing the wheel hub.
3. Brake bias toward the front makes rear drum brakes adequate for most light truck applications. Drum rear brakes provide for an emergency brake system.
4. Old brake fluid can be reused. Contaminants like moisture are of little concern, plus think of the money saved.
5. Breathing asbestos dust is very harmful. Brake pads with suspected asbestos content must be handled safely. Asbestos-free replacement lining is better for your health.
6. When checking rotor runout, temporarily adjust the wheel bearings to zero endplay. This keeps the rotor on center and provides a more accurate dial indicator reading.
7. Residual hydraulic pressure is useful on disc brakes. Brake drag keeps the pads warm and ready for action.
8. When testing a manual proportioning valve, start with any setting. You should be able to control the vehicle. Instructions from the manufacturers are all the same.
9. Shop manuals call for isopropyl or denatured alcohol to clean hydraulic brake cylinders. Always keep mineral- and petroleum-based products away from rubber products.
10. When forming brake tubing, the ends must be flared. If you don't have a quality double flaring tool, a single flare like copper tubing will do. DOT safety regulations are just to scare people.
