Brake fluid is pressurized by the brake master cylinder and then transmits that pressure to the brake calipers and the wheels. The amount of pressure in the brake fluid is determined by how hard you press down on the brake pedal. As the brake fluid travels throughout the braking system, it lubricates many of the internal braking components and protects them from corrosion.
Signs of bad brake fluid
- Check engine light or ABS warning light illuminates
- Brake fluid leak
- Difficulty braking
- Dirty brake fluid
- Low brake fluid level
Brake fluid maintenance
If you notice any of the above signs, get your vehicle serviced by a car care professional right away. It is unsafe to operate your vehicle with bad brake fluid as your brake become less effective. Once at the shop, your technician will determine whether to bleed the brakes or flush the brakes. Bleeding the brakes involves pumping new brake fluid through the brake lines to eliminate any air pockets that may have developed. Flushing the brakes replaces all of the brake fluid in your braking system, including the fluid in your brake lines and in the brake fluid reservoir, with new and clean brake fluid. Whichever process is chosen will be dependent on the manufacturer’s recommendations for your make and model of vehicle as well as the technician’s professional opinion.
