can't find a leak anywhere it blows fuses for the ecm its been doing this for years i just unhooked wire for rear brake light and the fuse blowing stoped what gives?

 

If you can't see the fluid leak, then I would suspect a caliper is leaking, just have to look harder. As far as the fuse blowing, if you are unhooking the rear light at the assy, then I would suspect that either the fuse is to small a value, or something is running at too high of a load in that circuit.

 

You should bend the foot brake that hit the switch for the tail light. this should take care of the fuse part.

 

on the foot brake where it comes in contact with brake light switch bend the tab so it does not push on switch so hard this should take care of blowing fuses
