My brake pedal is going to floor we changed front brakes

Hello,

There are few reasons for the brake pedal to go to the floor.

It can be due to a leak in the system, air in the brake line, bad master cylinder or calipers.
Inspect the other side that you have not replaced the caliper. Also look for any leaks.

Keep in mind that if the proper sequence does not get followed the brake lines can still have air in it even after bleeding.
Here is a proper method of brake bleeding:

I have attached the brake bleeding as well as master cylinder priming procedure below.

Please let me know if you have any questions.
Thank you.
