Signs a wheel cylinder may need replacing include brake fluid seeping inside the drum or onto the backing plate, a soft or low brake pedal, or pulling to one side when braking. These symptoms can have other causes, so diagnose the brake system before replacing parts. After installation, bleed the brakes and follow the vehicle service information.
