DIY Brake Fluid Change: How to Change Brake Fluid at Home

Brake fluid is vital to your vehicle’s braking system, transferring force from the brake pedal to the brake pads. Over time, brake fluid can absorb moisture and become contaminated, reducing braking efficiency. This DIY brake fluid change guide explains how to safely replace your brake fluid at home to keep your brakes responsive and safe.

Why Change Brake Fluid?

• Maintains optimal braking performance
• Prevents corrosion inside brake components
• Improves safety and control
• Extends life of brake system parts

Tools and Materials Needed

• New brake fluid (check your vehicle’s specifications)
• Brake bleeder kit or clear tubing and container
• Wrench to open bleeder valves
• Jack and jack stands
• Gloves and safety glasses
• Rags for cleanup

Step-by-Step Brake Fluid Change Process

Step 1: Prepare Your Vehicle

Park on a level surface, engage the parking brake, and raise the vehicle with a jack and jack stands if needed.

Step 2: Locate the Brake Fluid Reservoir

Find the brake fluid reservoir under the hood and remove the cap.

Step 3: Remove Old Brake Fluid

Using a turkey baster or similar tool, extract old fluid from the reservoir to make room for new fluid.

Step 4: Fill with New Brake Fluid

Add fresh brake fluid to the reservoir, keeping it near the “Full” mark.

Step 5: Bleed the Brakes

Starting with the wheel farthest from the master cylinder (usually the rear passenger side), attach clear tubing to the bleeder valve and place the other end in a container.

• Have a helper press the brake pedal several times and hold it down.
• Open the bleeder valve to let fluid and air escape, then close it before the helper releases the pedal.
• Repeat until clear, bubble-free fluid comes out.

Repeat this process on each wheel moving closer to the master cylinder.

Step 6: Check and Top Off Fluid

Keep the reservoir topped off throughout bleeding to prevent air from entering the system.

Step 7: Clean Up and Test

Replace the reservoir cap, clean any spills, lower the car if lifted, and test the brake pedal for firmness before driving.

Tips for a Successful Brake Fluid Change

• Use the brake fluid type recommended by your vehicle manufacturer
• Never reuse old brake fluid
• Perform brake fluid changes every 2 years or as specified in your owner's manual
• Wear protective gloves and eye protection

Conclusion

Changing your brake fluid at home is a valuable maintenance task that helps ensure safe, reliable braking. By following this guide carefully and observing safety precautions, you can extend the life of your brake system and maintain peace of mind on the road.
