Nissan 46501-ZH30A Brake Pedal Assembly with Bracket

On vehicles equipped with electrically adjustable pedals, move the pedals to their lowest position (closest to the floor) before checking or adjusting the brake pedal height. To check the brake pedal released height, remove the brake light and speed control switches. Peel back the carpet and insulator pad. With the brake pedal fully released, measure the distance from the top of the pedal to the floor. If the height is not correct, it must be adjusted. Loosen the pushrod locknut just in front of the power brake booster clevis. Turn the booster pushrod until the pedal height is correct. Tighten the locknut and reinstall the brake light and speed control switches. After adjusting the pedal height, check the freeplay. Press down lightly on the brake pedal and measure the distance that it moves freely before resistance is felt. The freeplay should be within the measurements. If it isn't, check and adjust the pedal height. Check the pedal depressed height only after the brake pedal released height and freeplay are within specification. With the engine running, press the brake pedal fully and measure the pedal pad-to-floor distance. If the height is less than the specified measurement, check the brake system for fluid leaks or other damage.
