there is too much in the container If you filled the resevior with brake fluid PRIOR to replacing any of the brake linings, it will cause the fluid to "backflow" into the resevior, thus it will overflow and leak from the cap.
Have you checked to make sure your brakes do not need replacing? Also, check your brake fluid. Low fluid can cause that light to appear as well.
Things you need to check is brake fluid oil, and brake pads. If they are fine then it is the brake switch which needs replacing. Also check the handbrakes as sometimes it is left engaged.
You get brake fluid that will cause tooth decay
If you feel like replacing a transmission soon, sure. Otherwise, no.
you forgot to plug in the brake fluid sensor.
A brake fluid leak in the brake system, LOW BRAKE FLUID.
It could be. If you fill it and it drains quickly, then yes it needs repair. But sometimes brake fluid just lowers over time and the fluid is all that needs replacing.
No
if your brake fluid is low, you probably need to replace your brake pads. If your pads are good and you fluid is low, you have a leak somewhere. By replacing your pads, the brake fluid level will rise to the proper level. If you add fluid now, then replace your pads, brake fluid will leak out the top of your fluid reservoir and most likely eat the paint off what ever it spills on. Brake fluid and car paint DO NOT MIX.
Sounds like air in the brake lines or power steering fluid in the brake system instead of brake fluid.
Worn brake shoes or pads. A leaking brake pipe. Low brake fluid. Air in the brake fluid pipe.
