  • If the brake fluid level is OK, the fault in the brake system may have been caused by a failure of the ABS control function.
  • If air enters your brake lines, the vehicle will be difficult to stop. 
  • If the brake warning light flashes, it indicates there is a major problem with the brake system. 
  • Driving with the BRAKE light on can increase the risk of fatal accident. 
  • A fault code may be stored in the brake module or ABS module if the brake fluid level is low. 
  • Brake fluid level is monitored electronically. 
  • It is normal for the brake fluid level to drop slightly to compensate for brake pad wear. The level will rise again when brake pads are replaced. This is normal.
  • The brake fluid level should never drop below the MIN mark or drop in a short time. 
  • Do not spill brake fluid on the paint or body of your vehicle. Brake fluid will damage the paint. 
  • Only use new brake fluid. Water (moisutre) in the brake fluid can cause corrosion in the brake system over time.
