Where pedal effort becomes pressure

The master cylinder turns what your foot does into hydraulic pressure at all four wheels. When its internal seals wear, pressure leaks back past them instead of reaching the brakes.

The classic sign is a pedal that sinks slowly to the floor under steady pressure while the fluid level stays put and nothing is wet on the ground — the fluid is going nowhere, it is simply slipping past the seals inside.

Bleed thoroughly and use fresh fluid

Bench-bleed the cylinder before fitting it. Doing that first saves a long session at the wheels chasing air that will not come out.

Use fresh fluid from a sealed container. Brake fluid absorbs moisture from the air, and moisture is what corrodes cylinder bores and lowers the boiling point exactly when hard braking needs it highest.
