The vehicle drives but brake pedals almost hit the floor and somewhat begin to break. And the back rear inner rim has black greasy residue, I do not think it has any odour or anything the rear back rotor is covered with that greasy residue, the driver side tho rotor is silver and hot to the touch and makes some sort of sound of like a grind. But on the passenger side rear that rotor is not even hot when I stop from driving a distance but is covered in the greasy black residue? Im not sure what it could be as I am not mechanically inclined I have been told by other it could be Calliper. Or break cylinder or wheel bearings, also my brake warning light stays on

Have a pro check this it can be an abs problem as well as the rear axle seal that has probably let go causing the residue. Or the brakes are worn so badly that it has blown a sseal on the caliper.

Okay I just added brake fluid as it was low, but brakes still do not work and the brake fluid I had just added is leaking from that rear passenger side rear where it has that black grease residue on the inner rim what could it be?

It's either a caliper or a wheel cylinder if you have disc or drum brakes in rear have a pro fix this I'd bet your pads are completely worn out all around the car and you are in need of a brake job.

I was told maybe a caliper also and yes they are disc brakes to so going to have a pro look into this soon.. Yeah so going to try and get a new caliper and have it installed and hope that its the problem cause there is no brakes on it completely now no pressure whatsoever. When applying brakes when I checked under and had someone push brakes, a "squishy" gurglin sound happens and can see the fluid leak on the rotor
