Why You Should Change Your Brake Fluid Regularly
Brake fluid is essential for safe braking performance. Over time, it absorbs moisture, which lowers its boiling point and can lead to brake failure. Changing brake fluid every 2-3 years is recommended to ensure your car stops safely.
Tools and Supplies You’ll Need
Before starting, gather these items: brake fluid (check your owner’s manual for the correct type), a wrench, a clear plastic tube, a bleeding kit, a brake fluid catch bottle, and gloves.
Step 1: Prepare Your Vehicle
Park on a level surface, use jack stands to lift the car, and remove the wheels if necessary. Locate the brake master cylinder and clean the area around the cap to prevent contamination.
Step 2: Drain Old Brake Fluid
Attach the clear tubing to the brake bleeder valve and place the other end in the catch bottle. Open the valve with a wrench and slowly pump the brake pedal to flush out old fluid. Repeat until clean fluid flows.
Step 3: Refill with New Fluid
Refill the master cylinder with fresh brake fluid, ensuring it never runs dry to avoid air entering the system. Keep checking the level as you bleed each wheel.
Step 4: Bleed the Brake System
Starting from the wheel farthest from the master cylinder, open the bleeder valve and have an assistant press the brake pedal. Tighten the valve before releasing the pedal to prevent air from being sucked back in.
Step 5: Test Your Brakes
Reinstall wheels, lower the car, and test the brakes in a safe area. The pedal should feel firm. If it’s spongy, repeat the bleeding process.
Safety Tips
Wear gloves to avoid skin contact with brake fluid, which is corrosive. Dispose of old fluid at a recycling center—never pour it down the drain.
When to Seek Professional Help
If braking issues persist after a fluid change, consult a mechanic. Leaks, air in the system, or worn brake components may require expert attention.
