Common symptoms that you may be low on brake fluid include the Brake Light warning staying on when you drive the car or the CHECK BRAKE SYSTEM warning message on the dashboard.

First, you check and make sure the parking brake is fully released. Next, follow the instructions below to check the Acura brake fluid level.



Symptoms of low brake fluid levels on an Acura usually start with a message on your instrument cluster.

Typical messages include "Check Brake System."

You won't get a message in older Acura's, but the brake light will stay on when driving. Other lights that may come on due to low brake fluid levels include the ABS and VSA lights.

  • Low Brake Fluid Warning
  • Brake Light On
  • The brake pedal is soft.
  • The brake pedal can be pressed all the way.

What you will need

Acura recommends that you use Honda DOT 3 or DOT 4 brake fluid. What brake fluid your Acura requires is printed on top of the brake fluid reservoir cap.

According to the Acura owner's manual, using a non-Honda brake fluid can cause corrosion and decrease the brake system's life (Source: 2004 Acura TL page 211).

These instructions apply to various 1998-2019 ACURA models such as CDX, CL, VSX, EL, ILX, Integra, Legend, MDX, NSX, RDX, RL RLX, RSX, SLX, TL TLX, TSX, Vigor, ZDX.

Troubleshooting Tips

If the brake fluid isn't low and the "Check Brake System" remains on, the problem can be due to the brake system's malfunction. Check the brake pads and ABS wheel speed sensors.

Also, check the fusible link for the ABS module. The fusible link is located in the engine bay of your Acura.

When the fusible link is blown, you will get multiple warning lights on your instrument cluster, and the push START/STOP may not work.
