Brake Problem need help today please

On My way into work this morning in stop and go traffic my brakes lost all thier pressure, after pumping the brake real quick a couple times my truck mustered up enough to get me into work. I just checked on it and saw that like i thought there was brake fluid leaking. The inside of my right rear tire is covered in fluid and i myself have never worked on drum brakes, on top of that im not willing to drive it home today after work with a brake fluid leak, does anyone have any ideas as to what may be leaking in my brake so i can get it done this afternoon. any help is appreciated

welcome to the autoforum. normally giving details of what vehicle we are having issues with helps. however in your case this is just the typical GM brake line defect. these brake lines rust out . I have had 2 failures myself even with periodic inspections.

the other item could be the brake cylinder of that wheel . the brake drum maybe too worn /too lagre now and with the shoes worn cause the brake cylinder to blow out.

when a brake line blows you will have no brakes. if you know what your doing you could crimp the defective line and then have some braking as well as reduce the fluid leaking until repairs can be made.

so have your vehicle checked for these brake issues whenever you do your oil changes and lube .
