i replaced the brakes on a 2000 Ford Explorer but now i cant get them to bleed on 2000 Ford Explorer

The brakes were starting to go almost all the way to the floor, so I changed the front brakes and now I can't get them to pump back up.

The problem is the master cylinder. Assuming the front is disc then your peddle pressure will remain constant with a little more travel as the rear shoes wear down. Have the master cylinder replaced.

I checked the master cylinder and it looks like its working.... but I see the brake lines going into a black box located beside the master. It has a total of 5 lines going into it. Do ya know what its called and could it be out?

That is the abs.There is a procedure to bleeding abs. You also need a non return valve if you are doing it alone. Vehicle must be running

You need to get some hands-on help with this. Probably from a mechanic before doing any more work on your brakes!!
