Symptoms

•Brake warning light illuminated on the dashboard
•Soft or spongy brake pedal feel
•Decreased braking performance
•Visible fluid on the ground or under the vehicle
•Fluid level in the brake fluid reservoir consistently low

Diagnostic Steps

1
Inspect the Brake Fluid Reservoir: Check the fluid level in the reservoir and inspect for any signs of fluid seeping from the cap or around the reservoir itself.
