Brake Disc Caliper problems of the 2006 Nissan Frontier

Braked hard to avoid collision with deer crossing highway and vehicle did not stop quickly as expected. Due for disc brake pad replacement in the future and this incident prompted a check of brake components. Discovered left and right rear axle seals, pinion seal and rear differential cover leaking differential fluid. Rear brake calipers, brake pads, parking brake assemblies and rotors were covered with differential fluid. Entire rear differential assembly overpressurized due to faulty, poorly designed oem check relief valve, resulting in failure of all seals. Same concern as in service bulletin ntb-10-008. Same problem with Nissan Frontier, exterra, titan and armada models. Nissan admits that fluid from the rear axle leaking onto the brake pads is a concern, but will not address why the axle seals are failing at an alarming and premature rate. A recall is needed for Nissan to take responsibility for their design flaw. All fluids personally changed out at 66,680 miles on 8/25/2011 and there was no evidence of leakage anywhere at that time.

The consumer stated the left front caliper would seize. The vehicle was taken to the dealer and they replaced the front pads and turned the front rotors. When the consumer took the vehicle for a tire rotation, it was discovered all four rotors needed to be replaced. The consumer believed the problem was due to contaminated brake fluid.

The left rear brake assembly bolts fell out and the caliper flopped off the disc.
