Parts for your 2012 Nissan Pathfinder-Brake shoes

2012 Nissan Pathfinder brake-shoes: what they do and when to replace them

Brake-shoes are used on the 2012 Nissan Pathfinder (R51). Technical sources including the Nissan Pathfinder R51 Electronic Service Manual (2012, sections BR and PB) and Nissan genuine parts catalogues specify rear disc brakes with a drum-in-hat parking brake that uses internal brake-shoes. Workshop databases commonly used in AU/NZ trade settings also list a shoe-and-hardware kit for the rear parking brake on this model. That means the vehicle uses pads for normal braking at all four wheels, and separate brake-shoes inside the rear rotors for the handbrake/parking brake.

On this Pathfinder, the brake-shoes’ purpose is to hold the vehicle securely when parked, especially on hills, and to provide a mechanical backup if needed. When the driver pulls the handbrake, cables actuate a lever that expands the shoes against the small internal drum surface inside each rear rotor. Because they’re not used for service braking, these shoes usually wear slowly, but they can glaze, crack, delaminate, or become contaminated with oil or brake fluid. Common clues they’re due for attention include poor holding on inclines, excessive lever travel, scraping/grinding from inside the rotor hat, or a handbrake that won’t release cleanly.

Replacement typically involves removing the rear caliper and rotor, inspecting the shoe linings and the return springs/adjuster, and replacing the shoes as a set along with fresh hardware. Contact points on the backing plate should be lightly lubricated with high-temperature brake grease (never the friction surfaces), and the star-wheel adjuster set so the drum just brushes the shoes, then backed off slightly. After refitting, the cable/lever travel is adjusted to spec per the service manual, followed by a gentle bed-in (several low-speed applications) so the shoes seat evenly.

• Inspect shoe linings and hardware whenever the rear rotors are off, or at major services (around every 20,000–30,000 km).
• Adjust the star-wheel and handbrake cable if lever travel grows or hill-holding worsens.
• Check for axle seal leaks that can soak the linings
