A sticky Nissan brake caliper isn't a lot of fun. After all, it never fails that one Nissan brake caliper will stick while its companion on the opposite wheel will work just fine. The end result is that you hit the brakes and the car lunges to the side with the working Nissan brake caliper. The last thing you need when you're coming to a stop is a lack of directional control, but that's exactly what you get when you have a malfunctioning Nissan brake caliper. So what causes this kind of problem? Corrosion is the number one killer of Nissan brake caliper units. The Nissan brake caliper is filled with brake fluid, and brake fluid absorbs moisture from the air over time. If you change your brake fluid by flushing the system every year or two, you'll likely never have any moisture problems inside the Nissan brake caliper. But let's be honest: When's the last time you flushed your brake fluid? That's what we thought. Anyway, the moisture causes corrosion to form on the precisely machined piston linings in the Nissan brake caliper. One day, when it finally gets bad enough, you hit the brakes and the piston seizes in the Nissan brake caliper bore. Voila: brakes on one side but not on the other. Fortunately, changing a Nissan brake caliper is about as simple as automotive repair work comes, and it'll give you a chance to replace those grungy down-to-the-metal brake pads you've been torturing your Altima's rotors with too. You can get a plain, unloaded Nissan brake caliper and choose your favorite brake pads, or pick a loaded Nissan brake caliper set with pads already installed. It's your choice, but either way make sure you get your Nissan brake caliper from us to get the best possible price.
