The master cylinder converts force from the brake pedal into hydraulic pressure, which travels through the brake lines to the wheels. Signs it may need replacing include a soft or slowly sinking pedal, fluid seeping from the cylinder body, and a brake fluid level that keeps dropping. These symptoms can also come from other parts of the brake system, so diagnose the cause before replacing it.
