The brakes are squishy. Do they need to be bled?
It is possible that the brakes may just need to be bled. Over time, brake fluid will absorb moisture out of the air. When the fluid absorbs too much moisture, the fluid is no longer able to effectively work, giving the pedal a squishy feeling. Bleeding the brakes will accomplish the task of flushing out the old fluid. It is also possible that your drum brakes may need to be adjusted. When the rear brake shoes wear, the hydraulic cylinder that activates them has to move farther than it normally does. When this happens the pedal moves farther than normal giving a squishy feeling. I would ask for help from one of the mechanics at YourMechanic so they can diagnose and repair the problem with your brakes.
