Signs a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid leaking at the cylinder, and a fluid level that keeps dropping. Other brake components can cause the same symptoms, so diagnose the system before replacing parts. Consult the vehicle service information for the correct mounting fasteners and whether they may be reused. Bleed the brake system as directed by the service procedure.
