Signs a master cylinder may need replacing include a soft or slowly sinking brake pedal, brake fluid seeping from the cylinder, a dropping fluid level or an illuminated brake warning light. These symptoms can have other causes, so diagnose the brake system first. If the master cylinder is at fault, this unit replaces it.
