Component | Procedure | ||||
Brake Booster (A) | Check brake operation by applying the brakes during a test drive. If the brakes do not work properly, check the brake booster. Replace the brake booster as an assembly if it does not work properly or if there are signs of leakage. | ||||
Piston cup and pressure cup inspection (B) |
| ||||
Brake hoses (C) | Look for damage or signs of fluid leakage. Replace the brake hose with a new one if it is damaged or leaking. | ||||
Caliper piston seal and piston boots (D) | Check brake operation by applying the brakes. Look for damage or signs of fluid leakage. If the pedal does not work properly, the brakes drag, or there is damage or signs of fluid leakage, disassemble and inspect the brake caliper. Replace the boots and seals with new ones whenever the brake caliper is disassembled. |
1. Reservoir
2. Reservoir pin
3. Grommet
4. Master cylinder
5. Booster
1.Run the engine for one or two minutes, and then stop it. If the pedal depresses fully the first time but gradually becomes higher when depressed succeeding times, the booster is operating properly, if the pedal height remains unchanged, the booster is inoperative.
2.With the engine stopped, step on the brake pedal several times.Then step on the brake pedal and start the engine. If the pedal moves downward slightly, the booster is in good condition. If there is no change, the booster is inoperative.
3.With the engine running, step on the brake pedal and then stop the engine.Hold the pedal depressed for 30 seconds. If the pedal height does not change, the booster is in good condition, if the pedal rises, the booster is inoperative.If the above three tests are okay, the booster performance can be determined as good.Even if one of the above three tests is not okay, check the check valve, vacuum hose and booster for malfunction.
1.Turn ignition switch OFF and disconnect the negative (-) battery cable.
2.Remove the battery.(Refer to Engine Electrical System - "Battery")
