Follow this step-by-step DIY guide to properly check your brake fluid and top it off, if needed.
What Are The Signs Of Low Brake Fluid?
During normal operation, a car should never lose brake fluid. The level only slightly drops due to wear and tear of the brakes. If the level is low, it’s likely there’s a leak somewhere.
Your car takes a specific type of brake fluid and should never be mixed. In most newer cars, it will often outline the type of fluid needed on the brake fluid reservoir cap. Check your owner’s manual for confirmation.
How To Check Your Brake Fluid
Use these steps below to properly inspect your brake fluid level.
Step 1. Find Brake Master Cylinder Reservoir
- The brake master cylinder reservoir is typically mounted on or near firewall at the back of the engine compartment.
- This will be almost directly in front of where the brake pedal is usually mounted on the other side of bulkhead.
- If you are having issues trying to find it, reference your owner’s manual.
Step 2. Inspect Fluid Level
- The majority of newer vehicles feature a translucent reservoir with a “full” line clearly marked.
- In this case, you can check the fluid level without needing to remove its cap.
- For older vehicles, there will be a metal reservoir with a top secured by a spring-loaded clamp.
- Wipe clean the exterior cap to prevent any debris from contacting the brake fluid.
- You’ll need to pry the clamp to one side, lifting the top off to check its level.
- The “full” line should once again be clearly marked.
Step 3. Add Fluid To The “Full” Line
- It’s important to note a decrease in brake fluid indicates that the brake pads are worn down.
- Brake pads should always be inspected by the auto care professionals.
- Always use the specific type of brake fluid recommended for your car.
- If your car features a dual-chamber reservoir, fill both chambers right up to the “full” line.
- If the reservoir appears extremely low or empty, refrain from driving your car.
- Also make sure to never overfill the brake fluid.
Step 4. Replace The Cap
- Replace the cap once the process has been completed.
- Make sure to always thoroughly wash your hands after working with brake fluid.
- Brake fluid can be extremely toxic.
What Happens If You Don’t Change Your Brake Fluid?
- Reduced Braking Efficiency: Contaminated or degraded brake fluid can lower the system’s boiling point, leading to brake fade or complete brake failure in extreme cases.
- Corrosion: Moisture in the brake fluid can lead to corrosion of internal brake components, such as the master cylinder, brake lines, and calipers, potentially causing extensive damage.
- Spongy Brake Pedal: As brake fluid degrades, it can cause the brake pedal to feel soft or spongy, reducing your ability to stop the vehicle effectively.
Replacing brake fluid every 2 to 3 years or 20,000 to 45,000 miles is a good general guideline. However, always consult your vehicle’s owner’s manual for the manufacturer’s specific recommendation.
Regular brake fluid maintenance is crucial for ensuring optimal braking performance and safety. If you notice any changes in your braking system, such as a soft pedal or reduced stopping power, have your brake fluid checked and replaced if necessary.
