When pressing the brake pedal, it goes all the way down to the floor without any traction, the car is still moving. When I looked under the hood, the brake fluid reservoir is full of brake fluid. I had never replaced the brake master cylinder before and I am not sure what would be the appropriate steps to go forward in resolving this issue. I did some research on this issue and maybe I need to do some more. From what I gathered so far, it seems the brake master cylinder needs to be replace, flush and drain the old brake fluid. Put in new brake fluid, and bleeding the brakes. What about brake power booster, does that need to be replace as well? No sign of any leaking brake fluid anywhere. Any ideas and/or comments is greatly appreciated. I will follow through on this thread and doing more research on this issue and will post my findings and/or successful solution to this issue. Thanks to all for reading this post.

Look very closely at the fluid reservoir particularly the rear section. It can be empty but hard to see because of a dam inside. If it is empty you need to find out why. It is probably from a leak.

Good luck!!!

Hi Sugar Bear, great to hear from you. Thank you for your post. The brake fluid reservoir is full and clear brake fluid. I suspected the brake master cyclinder is worn out and need to be replace. I will follow up on this. Stay tune.
