Brake Warning Light (Red)

How to Fix It

1. Check the parking brake.

   Ensure the parking brake lever, pedal, or button is fully released. On Ford models with an electronic parking brake, press the EPB button to release. Driving with the parking brake partially engaged is a common cause of this warning — even slight engagement triggers the light.

2. Check brake fluid level.

   Open the brake fluid reservoir (translucent plastic container near the firewall under the hood). If the level is between MIN and MAX, fluid level is not the cause. If the level is below MIN, add DOT 3 or DOT 4 brake fluid (check the reservoir cap for the correct specification) and investigate the cause of the fluid loss.

3. Inspect brake pads for wear.

   Low brake fluid when pads are worn is normal — as pads wear down, caliper pistons extend further, pulling fluid from the reservoir. If the fluid is low and no leak is visible, the pads are likely worn past the minimum thickness. Have the brake pads inspected — they likely need replacement.

4. Check for a brake fluid leak.

   Inspect under the vehicle for dripping brake fluid — it is a clear to slightly yellow oily liquid. Check around each wheel (brake caliper area), along brake lines under the car, and near the master cylinder. A brake fluid leak is a serious safety issue — do not drive with a confirmed leak.

5. Check the brake master cylinder.

   If brake fluid is correct and there are no leaks but pedal feel is spongy or the pedal slowly sinks to the floor, the brake master cylinder has failed internally. A sinking brake pedal under steady pressure means the master cylinder is not holding pressure. This requires immediate professional repair — do not drive the vehicle.
