Main points
- Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the calipers, which in turn squeeze the brake pads against the rotors, slowing or stopping your car.
- This kit typically includes a bleeder screw wrench, a clear hose, a catch bottle, and a one-man bleeder.
- If the fluid is low, add new brake fluid to the reservoir until it reaches the “MAX” line.
Maintaining your Honda Civic‘s braking system is crucial for safe driving. Brake fluid, the lifeblood of your brakes, absorbs moisture over time, which can lead to reduced braking performance and even brake failure. This blog post will guide you through the process of changing brake fluid in your Honda Civic, empowering you to perform this essential maintenance task yourself.
Why Change Brake Fluid?
Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the calipers, which in turn squeeze the brake pads against the rotors, slowing or stopping your car. However, brake fluid is hygroscopic, meaning it absorbs moisture from the air. This moisture reduces the fluid’s boiling point, making it less effective at transmitting pressure.
Over time, moisture in the brake fluid can lead to:
- Reduced braking performance: The brake pedal may feel spongy or soft, requiring more pressure to stop the vehicle.
- Brake fade: The brakes may become less effective at high temperatures, leading to longer stopping distances.
- Corrosion: Moisture can corrode brake components, leading to leaks and other problems.
- Boiling point issues: In extreme conditions, the brake fluid may boil, resulting in brake failure.
To prevent these issues, it’s essential to change your brake fluid regularly. Honda recommends changing brake fluid every two years or 24,000 miles, whichever comes first.
Gather Your Supplies
Before you begin, make sure you have the following supplies:
- New DOT 3 or DOT 4 brake fluid: Check your Honda Civic’s owner’s manual to determine the recommended type of brake fluid.
- Brake fluid bleeder kit: This kit typically includes a bleeder screw wrench, a clear hose, a catch bottle, and a one-man bleeder.
- Clean rags: For wiping up spills and cleaning tools.
- Safety glasses: To protect your eyes from brake fluid splashes.
- Gloves: To prevent skin irritation from brake fluid.
- Jack and jack stands: To raise the vehicle safely.
- Wrench: To loosen the bleeder screws.
- Container for old brake fluid: It’s important to dispose of old brake fluid properly.
Prepare Your Honda Civic
1. Park your Honda Civic on a level surface.
2. Engage the parking brake.
3. Open the hood and locate the brake fluid reservoir. It’s usually a clear plastic container with a cap and a “MAX” and “MIN” markings.
4. Check the fluid level. If the fluid is low, add new brake fluid to the reservoir until it reaches the “MAX” line.
5. Clean the area around the reservoir and bleeder screws. This will help prevent dirt and debris from contaminating the new brake fluid.
Bleeding the Brakes
1. Start with the wheel furthest from the master cylinder. This is usually the rear passenger side wheel.
2. Open the bleeder screw slightly. Use a wrench to loosen the bleeder screw, but don’t open it completely.
3. Have someone pump the brake pedal several times. This will push the old brake fluid through the system and into the catch bottle.
4. Hold the brake pedal down.
5. Tighten the bleeder screw.
6. Release the brake pedal.
7. Repeat steps 2-6 until clear fluid comes out of the bleeder screw. This indicates that all the old fluid has been purged from the system.
8. Repeat the process for each wheel, working your way towards the master cylinder.
Refilling the Reservoir
1. Once all four wheels have been bled, add new brake fluid to the reservoir. Make sure to check the level frequently as you add fluid, as the reservoir will empty as you bleed the brakes.
2. Top off the reservoir with new brake fluid until it reaches the “MAX” line.
3. Close the reservoir cap.
Final Check and Drive Test
1. Start the engine and pump the brake pedal several times. This will ensure that the system is properly bled and that the brake pedal feels firm.
2. Take your Honda Civic for a test drive. Apply the brakes gently at first, then gradually increase pressure to ensure that the brakes are working properly.
3. Check for leaks. Look closely for any signs of brake fluid leaks after the test drive.
Time to Put Your Civic’s Brakes Back in Tip-Top Shape
Changing brake fluid is a relatively simple DIY task that can significantly improve your Honda Civic’s braking performance and safety. By following the steps outlined in this guide, you can confidently perform this essential maintenance yourself, saving money and gaining valuable knowledge about your vehicle.
What You Need to Know
Q: What type of brake fluid should I use for my Honda Civic?
A: Consult your Honda Civic‘s owner’s manual for the recommended type of brake fluid. It will usually specify DOT 3 or DOT 4.
Q: How often should I change my brake fluid?
A: Honda recommends changing brake fluid every two years or 24,000 miles, whichever comes first.
Q: What happens if I don’t change my brake fluid?
A: Not changing your brake fluid can lead to reduced braking performance, brake fade, corrosion, and even brake failure.
Q: Can I use a vacuum bleeder instead of a one-man bleeder?
A: Yes, a vacuum bleeder can be used to bleed the brakes. However, a one-man bleeder is a more convenient and affordable option for most DIYers.
Q: What if I have difficulty bleeding the brakes myself?
A: If you encounter problems bleeding the brakes, it’s best to take your Honda Civic to a qualified mechanic.
