I hope this how-to video helps you out and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks. In this video, we show you how to replace the rear brake caliper on this 2003 Nissan Altima. It's the same process on these Altima's from 2002-2006. We show you on the passenger side but it's the same process on the driver's side. The items you'll need for this is 8, 12, 14, 19, and 21 millimeter sockets and ratchet, and a piece of pipe for leverage, 14 millimeter wrench, brake fluid, Jack and Jack Stands, a torque wrench and a funnel.

You want to start off by removing your wheel. If you don't have air-powered tools, you want to loosen up those 21 millimeter lug nuts on the ground, raise the vehicle and remove them the rest of the way. Then you can pull your wheel off. Now is where you want to inspect your brakes. You can look in here and see how much life is left on your brake pads, then you want to feel your rotor and make sure it's not too deeply gouged. Ours is actually in really bad shape. We're going to start off by removing the caliper. You want to remove these 2 19 millimeter bolts. We'll just fast-forward as Don does this. You can see he's using that piece of pipe for some extra leverage to help break those bolts free. Once the bolts are removed, using a flat blade screwdriver, just pry that off. Then you can set that aside. The flexible brake line is held in place by a 12 millimeter bolt, just use a socket and ratchet or wrench to remove it. Reinstall the brake line. Make sure you put a new copper crush washer between the line and the caliper as well as the end of the bolt and the line. Then tighten that up and tighten that bolt to about 30-35 foot pounds.

Now you can reinstall the caliper and bracket and we'll install the brake shoes in later. Put the 19 millimeter bolts in place and you'll want to tighten those up to 85-90 foot pounds. Now you want to remove this 14 millimeter bolt right here. Once the bolt's removed, pull your caliper back and then push your brake pad slides into place. Once the slides are in place, you can put your brake pads back in. Push your caliper back into place and place that 14 millimeter bolt. We'll fast-forward here as Don tightens that up. Tighten these bolts up to 25 foot pounds. You'll want to bleed the brakes. Start out by loosening your bleeder screw and wait until it starts dripping fluid. When it drips fluid, then tighten it back up and this is just a gravity feed initially. To further bleed the brakes have a helper in the car press the brake pedal then loosen the bleeder and you'll see fluid will come out. Then tighten up the bleeder, have them let of the pedal and repeat that until there's no air in the lines. It usually takes 2 or 3 repetitions. Reinstall the wheel and tire and hubcap and then just tighten the lug nuts preliminarily.

Now torque the lug nuts to 100 foot pounds in crossing pattern. After bleeding the breaks, you're going to want to replace the brake fluid that was lost so fill your brake fluid up to the fill line. Make sure you replace your cap. After doing any repair on the brakes, before taking it out onto the road it's important to do a couple things first. First you want to just pump the brakes until the brake pedal firms up. Then you want to do a stop test from 5 mph and then 10 mph.
