N2 - Fluid Level Check, Brakes Applied









- Apply brakes very slowly several times while observing the fluid level in the master cylinder reservoir.

NOTE: Master cylinder bypass typically occurs when the brakes are applied very slowly and line pressures are low. A "hard" apply can flare the internal lip seals out and result in a passing test where the concern may in fact be valid.

- Does the level remain the same?

YES -- GO to N3. N3 - Wheel Turning Torque Check, Front Wheels

NO -- Master cylinder checks OK.
