Operation and Leakage Check

Component

Procedure

Brake Booster (A)

Apply the brake and check its operation during the test run. If it does not work properly, replace the brake booster. If the brake fluid is found inside the booster when disassembling, replace the booster and master cylinder.

Piston cup and pressure cup inspection (B)

•	Apply the brake and check its operation. See if there is any damage or an oil leakage. If it does not work properly or damaged or an oil leak is found, replace the master cylinder. If the brake fluid is found inside the booster, replace the booster too.

•	Check if there is any difference in brake stroke when it is applied quickly and slowly. If a difference is detected, replace the master cylinder.

Brake hoses (C)

See if there is any damage or an oil leakage. If there is any damage or an oil leak is found, replace the brake hose and washer with new components.

Caliper piston seal and piston boots

•	Apply the brake and check its operation.

•	If the brake pedal does not work properly, it means there is a brake-slip or damage or an oil leak. Replace the brake caliper with a new one.
