Hello. I am new here and am hoping someone could help me. About a month ago I bought an 1981 F250 Ford Ranger. I absolutely love the truck it's beautiful and in great shape. The other day I was parking on a steep incline so I set my e-brake for the first time since I got the truck. What I left my friend's house of course I took a break off and later that day I noticed my brake pedal was squishy. Within two days I ended up with absolutely no brakes. When I step on the pedal it goes all the way to the floor and it makes a squishy noise I don't know how else to describe it. I checked the master cylinder and it seems to be full of brake fluid so I'm not sure what I should do next... hopefully somebody has a good idea. Thank you in advance for all your help!

 

Check the inside of the rear tires for signs of brake fluid, could be a leaking wheel cylinder(brake slave)

E-brake wouldn't have much to do with that, unless it also no longer works well, using it could have broken rusted out parts inside the drum, which would have broke eventually anyway

 

Check to see if you have any brake fluid in the master cylinder. If you live in the rust belt I would check for signs on the brake lines themselves for leaks too.
