As a responsible car owner, it’s essential to know how to change brake pads on your Nissan Altima to ensure optimal performance and safety. In this comprehensive guide, we’ll walk you through the step-by-step process of replacing brake pads on your Nissan Altima, covering everything from preparation to completion.

Understanding the Importance of Brake Pads
Before we dive into the replacement process, it’s crucial to understand the significance of brake pads in your vehicle’s overall performance. Brake pads are responsible for converting the kinetic energy of your vehicle into heat energy, which helps to slow down or stop your car. Over time, brake pads wear out due to friction, heat, and usage, leading to a decrease in their effectiveness.
Ignoring worn-out brake pads can lead to severe consequences, including:
- Reduced stopping power, making it challenging to stop your vehicle in emergency situations
- Increased stopping distance, which can lead to accidents or near-misses
- Damage to other brake system components, such as rotors and calipers, resulting in costly repairs
- Compromised safety, putting yourself and others at risk on the road
Preparation and Tools Needed
Before starting the replacement process, make sure you have the following tools and materials:
- New brake pads (compatible with your Nissan Altima model)
- Brake lubricant (silicone-based or ceramic-based)
- C-clamps or piston compressor
- Tire iron or lug wrench
- Wheel chocks (optional)
- Jack stands (optional)
- Rag or paper towels
- Work light or flashlight (optional)
It’s also essential to consult your Nissan Altima’s owner’s manual or a repair manual specific to your vehicle’s make and model for detailed instructions and precautions.
Removing the Wheels and Brake Caliper
To access the brake pads, you’ll need to remove the wheels and brake caliper. Follow these steps:
Loosening the Lug Nuts
Before jacking up the vehicle, loosen the lug nuts on the wheel using a tire iron or lug wrench. Turn them counterclockwise until they’re loose, but do not remove them yet.
Jacking Up the Vehicle
Position the jack under the Nissan Altima’s frame and raise it until the wheel is off the ground. Make sure the jack is stable and sturdy to avoid any accidents. (See Also: How Long Does Halfords Brake Check Take? – Find Out Now)
Removing the Lug Nuts and Wheel
Now, remove the lug nuts completely and take off the wheel. Place the wheel aside and cover it with a rag or paper towels to prevent any dirt or debris from getting on the brake components.
Removing the Brake Caliper
Use a wrench or socket to loosen the brake caliper bolts. Remove the bolts and slide the caliper off the rotor. Be careful not to damage the brake hose or ABS sensor wires.
Removing the Old Brake Pads
With the brake caliper removed, you’ll have access to the old brake pads. Follow these steps:
Removing the Pad Wear Sensors
Locate the pad wear sensors, which are usually attached to the brake pads. Remove the sensors by pulling them out of their clips or connectors.
Removing the Old Brake Pads
Use a screwdriver or pliers to remove the old brake pads from the brake caliper. Take note of the pad’s orientation and position to ensure correct installation of the new pads.
Installing the New Brake Pads
Now, it’s time to install the new brake pads. Follow these steps:
Installing the New Brake Pads
Take the new brake pads and insert them into the brake caliper, making sure they’re properly seated and oriented correctly. Apply a small amount of brake lubricant to the back of the pads to reduce noise and vibration.
Reinstalling the Pad Wear Sensors
Reattach the pad wear sensors to the new brake pads, making sure they’re securely clipped or connected. (See Also: How to Use a Disc Brake Pad Spreader? Mastering the Technique)
Reinstalling the Brake Caliper and Wheel
With the new brake pads installed, it’s time to reinstall the brake caliper and wheel. Follow these steps:
Reinstalling the Brake Caliper
Slide the brake caliper back over the rotor, making sure it’s properly aligned. Tighten the brake caliper bolts in a star pattern to ensure even pressure.
Reinstalling the Wheel and Lug Nuts
Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle to the ground and then tighten the lug nuts in a star pattern to the recommended torque specification.
Bleeding the Brake System
After replacing the brake pads, it’s essential to bleed the brake system to remove any air that may have entered the lines. You can use a brake bleeding kit or take your Nissan Altima to a professional mechanic for assistance.
Testing the Brakes
Once the brake pads are replaced and the system is bled, test the brakes to ensure they’re functioning properly. Drive your Nissan Altima slowly and press the brake pedal to test the stopping power and feel.
