For months I have been getting this hot metal smell. About a week ago my brakes started going out. I checked the fluid and it was little low but not bad. Sometimes they worked and sometimes they didnt. So tonight they went out. I drove home slowly got it up on jack stands and took off the front tires. The front DS rotor was hot enough to give me a big blister on my finger. The PS was not. I let it cool down for about an hour. When I came back the hub on the DS was still very warm and PS was cool. So a couple of questions. The hot metal smell is difinitely coming from the hub on the DS. Why. The brake pads were fine on both sides. Do you think it is something to do with the brakes or do I need to be concerned about the inside of the axle? I dont know what to think. Why do my brakes work then dont work. Any help would be great.
