Noticed brakes felt soft, went to check fluid, noticed brake fluid was leaking out of cap and moisture was accumulating on reservoir-wiped away and the moisture returned, the fluid level was fine but continuously fluid is building up. Took to local Ford dealer they said it was fine, however didn't make an attempt to replace cap.
