Grinding and rubbin when breaking, seems to be getting worse. Only happens when breaking.

Breakpads could need adjusting, I had a similar thing happen, and come to find out, they were put in backwards!

Is it 4X4 ? Drive shaft

check for failed wheel bearings or loose wheel on studs. Check suspension ball joints and steering joints the problem is serious so have the front inspected by a competent mechanic

could be breaks,bearing.

Sounds to me like you have a bad front hub. The good news is that the wheel speed sensors are part of the wheel hubs. The tricky part can be to figure out which side is bad. If the noise is worse when turning right, it is most likely the left side that is bad. You could try jacking up each corner and shaking the wheels to see if there is any play.

are u ling the caliper notches up w/the notches in the brake pad .this may be the problem they not lined up w/notches an rubbin the rotors .

The only way that the fluid would get out is if the cups are bad in the brake cylinder or the adjuster on the break shoes has locked up and fallen off. You would hear a grinding noise if that happens. Also look at your break fluid resivor to see if it's low in the small side that will tell you if it has been leaking.

YOU NEED TO REPLACE THE BRAKES...ASAP
The sqeal was the brakes warning you that they were getting low, when they were sqeeling all the time, they were telling you they were about gone. Now that they are grinding, you will most likely need rotors as well. Get them replaced asap !
