If there was a leak at the wheel cylinders, the MC fluid level would go down. The OP said the fluid level has not changed, so back to the MC being bad.

Something you need to consider... It's the brakes... If they don't work you don't stop... Well, not until something gets in your way... When inspecting brakes you need to change your way of thinking....Or leave it to professionals cause doing it half assed can get you killed...

Wheel cylinders are cheap.... Not worth the risk IMO.. The linings wear out and you get grinding noises as the steel backing eats the drum/rotor but the car still stops.... You loose a wheel cylinder/flex hose/master cylinder & the pedal goes to the floor... Sometimes slowly, sometimes suddenly... When it gets to the floor you might get some braking action from whichever end isn't leaking.... Or not...

When inspecting the hydraulic portion of the brakes rolling back the dust boot and finding fluid means the inner seals are weeping, they don't always just dump fluid, but when they are weeping it's only a matter of time... Wheel cylinders are cheap, if you can't afford them wheel cylinder seal kits are even cheaper...

On Rock Auto wheel cylinder repair kits start at $0.72 and max out at just over $5..

If you can't afford that you can't afford to be driving an old car...
