Understanding Your Brake System
Before diving into the process of replacing brake pads, it’s essential to understand the basic components of your BMW X6 35i’s braking system. The brake system is a complex network of interconnected parts working together to slow down or stop your vehicle. Here are the key components involved:
Brake Pads
Brake pads are the friction material that presses against the brake rotors to create the force needed to slow down your vehicle. Over time, brake pads wear down due to friction. When the brake pads become too thin, they need to be replaced.
Brake Rotors
Brake rotors are the large, disc-shaped metal components that the brake pads clamp onto. Rotors are designed to withstand the high temperatures generated by braking and provide a smooth, flat surface for the brake pads to grip.
Calipers
Brake calipers are the mechanical devices that squeeze the brake pads against the rotors. They are hydraulically operated, meaning that brake fluid pressure from the master cylinder forces the caliper pistons to move, pushing the brake pads outward.
Brake Lines
Brake lines are the steel or rubber tubes that carry brake fluid from the master cylinder to the calipers. Brake fluid transmits the force applied to the brake pedal to the calipers, enabling the braking action.
Master Cylinder
The master cylinder is a hydraulic pump located in the engine compartment. It converts the pressure applied to the brake pedal into hydraulic pressure that is transmitted through the brake lines to the calipers.
Tools and Materials Needed
Before you begin, gather all the necessary tools and materials. Having everything on hand will make the process smoother and more efficient. Here’s a list of what you’ll need:
- Jack and Jack Stands: To safely lift and support the vehicle.
- Lug Wrench: To remove the lug nuts from the wheels.
- Socket Set: To loosen and tighten various bolts and nuts.
- C-Clamp or Brake Piston Compressor Tool: To compress the brake caliper pistons.
- Torque Wrench: To tighten lug nuts and other fasteners to the correct specifications.
- Brake Cleaner: To clean the brake components.
- Anti-Seize Compound: To prevent rust and corrosion on brake caliper bolts.
- New Brake Pads: Choose pads that are compatible with your 2013 BMW X6 35i.
- Gloves and Safety Glasses: To protect your hands and eyes.
Step-by-Step Brake Pad Replacement Procedure
Now that you have the necessary tools and materials, let’s proceed with the step-by-step brake pad replacement procedure for your 2013 BMW X6 35i: (See Also: Should I Change Brake Fluid? Know The Signs)
1. Prepare the Vehicle
Park your BMW X6 35i on a level surface, engage the parking brake, and chock the rear wheels to prevent the vehicle from rolling. Consult your owner’s manual for the recommended jacking points to safely lift the vehicle.
2. Remove the Wheel
Using the lug wrench, loosen the lug nuts on the wheel you want to work on. Once loosened, jack up the vehicle and secure it on jack stands. Remove the lug nuts completely and take off the wheel.
3. Access the Brake Caliper
Locate the brake caliper, which is the cylindrical component that houses the brake pads. You may need to remove a protective cover or dust shield to access the caliper.
4. Remove the Brake Pads
The brake pads are held in place by retaining clips or pins. Carefully remove these clips or pins to release the brake pads from the caliper.
5. Compress the Brake Caliper Pistons
Use a C-clamp or a brake piston compressor tool to gently compress the brake caliper pistons. This will create space for the new, thicker brake pads.
6. Clean the Brake Components
Use brake cleaner to thoroughly clean the brake caliper, rotor, and the area around the brake pads. This will remove any dirt, debris, or brake dust that may interfere with proper brake function.
7. Install the New Brake Pads
Slide the new brake pads into the caliper, ensuring they are properly seated. Reinstall the retaining clips or pins to secure the brake pads in place.
8. Reassemble the Wheel
Reinstall the wheel onto the hub, hand-tighten the lug nuts, and lower the vehicle using the jack. Once the vehicle is on the ground, tighten the lug nuts to the manufacturer’s specifications using a torque wrench. (See Also: Do I Need To Turn Rotors When Changing Brake Pads? The Truth)
9. Repeat for the Other Wheels
Follow the same steps to replace the brake pads on the other wheels of your BMW X6 35i. Remember to always work on one wheel at a time and to properly support the vehicle with jack stands.
Post-Replacement Inspection and Test Drive
After replacing the brake pads, it’s crucial to perform a thorough inspection and test drive. Here are some key points to check:
* **Brake Pedal Feel:** The brake pedal should feel firm and responsive. If the pedal feels soft or spongy, there may be an issue with the brake system that requires further investigation.
* **Brake Performance:** Test the brakes in a safe, controlled environment. Apply the brakes gradually and ensure that the vehicle stops smoothly and effectively.
* **Noise and Vibration:** Listen for any unusual noises or vibrations while braking. These could indicate a problem with the brake pads, rotors, or other components.
* **Brake Fluid Level:** Check the brake fluid level in the master cylinder reservoir. If the level is low, it could indicate a leak in the brake system.

Frequently Asked Questions
How often should I replace my brake pads?
Brake pad lifespan varies depending on driving habits, road conditions, and other factors. As a general guideline, it’s recommended to inspect your brake pads every 12,000 miles or once a year. If they are worn down to less than 1/4 inch, it’s time for replacement.
What are the signs of worn brake pads?
Some common signs of worn brake pads include a squealing or grinding noise when braking, a decrease in braking performance, and a vibration in the steering wheel.
Can I drive with worn brake pads?
Driving with worn brake pads is dangerous and can lead to brake failure. It’s essential to replace worn brake pads as soon as possible to ensure safe and reliable braking.
What type of brake pads are best for my BMW X6 35i?
Consult your owner’s manual or a trusted mechanic to determine the best type of brake pads for your specific vehicle. There are different types of brake pads available, such as ceramic, semi-metallic, and organic, each with its own advantages and disadvantages.
Is it necessary to replace brake rotors when changing brake pads?
Brake rotors can sometimes be resurfaced if they are within the acceptable thickness limits. However, if they are heavily scored, warped, or have excessive wear, they should be replaced. It’s best to consult a mechanic to determine the condition of your rotors.
