Quick facts
- Part: Dorman M630540 brake master cylinder
- Fits: 2002-2006 Nissan Sentra
- Material: Aluminum
- Condition: New
A soft or sinking pedal, or brake fluid showing around the cylinder, can mean a master cylinder is worn. A leak or low fluid elsewhere in the brake system can also leave the pedal soft, so with the engine off, look over the cylinder, reservoir and lines for wet spots and check the fluid level before replacing anything. If a worn master cylinder is the cause, this one replaces it.
