Maintaining the brakes of your Mazda CX-5 is crucial for your safety on the road. One of the most important components of the braking system is the brake fluid. Over time, the brake fluid can degrade and become contaminated, which can lead to reduced braking performance and potentially cause damage to other components of the braking system. Changing the brake fluid is a relatively simple process that can be done at home with the right tools and knowledge. In this article, we will guide you through the process of changing the brake fluid in your Mazda CX-5.

Why Change Brake Fluid?
Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the brake calipers, causing the brake pads to clamp onto the rotors and slow or stop the vehicle. Over time, the brake fluid can become contaminated with moisture, air, and debris, which can cause it to degrade and lose its effectiveness. If the brake fluid is not changed regularly, it can lead to a range of problems, including:
- Reduced braking performance
- Brake pedal sponginess or softness
- Brake fluid leakage
- Brake caliper corrosion
- Brake pad wear
Changing the brake fluid regularly can help to prevent these problems and ensure that your brakes continue to function properly. It is recommended to change the brake fluid every 30,000 to 50,000 miles, depending on the type of brake fluid used and the driving conditions.
What Type of Brake Fluid to Use?
Mazda recommends using a DOT 4 brake fluid in their vehicles. DOT 4 brake fluid is a type of glycol-based brake fluid that is designed to provide high-performance braking in a wide range of temperatures. It is also compatible with most brake components and is suitable for use in both conventional and ABS braking systems.
When selecting a brake fluid, make sure to choose one that meets the following specifications:
| Specification | Value |
|---|---|
| DOT Rating | 4 |
| Viscosity | 3.5 mm2/s at 100°C |
| Freezing Point | -40°C |
| Boiling Point | 230°C |
Tools and Materials Needed
To change the brake fluid in your Mazda CX-5, you will need the following tools and materials:
- Brake fluid flush kit
- Brake fluid
- Funnel
- Rag
- Safety glasses
- Wheel chocks
It is also recommended to have a pair of gloves and a pair of jack stands to support the vehicle while you are working underneath it. (See Also: How to Use Foot Brake? Mastering Safe Driving Techniques)
Step-by-Step Instructions
Changing the brake fluid in your Mazda CX-5 is a relatively simple process that can be completed in about an hour. Here are the step-by-step instructions:
Step 1: Locate the Brake Fluid Reservoir
The brake fluid reservoir is located on the driver’s side of the engine compartment. It is a clear plastic reservoir with a cap on top.
Step 2: Remove the Cap and Check the Fluid Level
Remove the cap from the brake fluid reservoir and check the fluid level. The fluid level should be at the “MIN” mark on the side of the reservoir.
Step 3: Remove the Brake Fluid Flush Kit
Remove the brake fluid flush kit from the packaging and attach it to the brake fluid reservoir. Make sure that the kit is securely attached and that the hose is not kinked.
Step 4: Bleed the Brake System
Bleed the brake system by pressing the brake pedal several times to remove any air that may be present in the system. You may hear a hissing sound as the air is released from the system.
Step 5: Add New Brake Fluid
Add new brake fluid to the reservoir through the brake fluid flush kit. Make sure to use the correct type of brake fluid for your vehicle. (See Also: How Many Miles Till Brake Pads? The Ultimate Mileage Guide)
Step 6: Replace the Cap and Check the Fluid Level
Replace the cap on the brake fluid reservoir and check the fluid level to make sure it is at the “MIN” mark.
Step 7: Test the Brakes
Test the brakes by pressing the brake pedal several times to make sure they are functioning properly.
Recap and Conclusion
Changing the brake fluid in your Mazda CX-5 is a relatively simple process that can be completed in about an hour. By following the steps outlined in this article, you can ensure that your brakes are functioning properly and that your vehicle is safe to drive.
Remember to check the brake fluid level regularly and to change it every 30,000 to 50,000 miles, depending on the type of brake fluid used and the driving conditions. It is also important to use the correct type of brake fluid for your vehicle and to follow the manufacturer’s recommendations for brake fluid maintenance.
