The metal rotor that the brake pads squeeze together can sometimes vibrate, causing a squeaking noise. Luckily, there are several ways to fix this: 1  Use a milk spray, lotion or cream on the back of the pads [source: Allen].  Use sandpaper to sand off surface hardening of the brake pad/shoe surface.
Your brake fluid level does fall normally with the years as your disc pads and rotors wear down, leaving the caliper pistons further and further extended in the cylinder. If you have rear brake shoes and drums, their wearing will make the pedal softer and softer, but the return springs may keep the reservoir level up. But the usual reason for the fluid level to drop through the bottom, especially in cases of outright brake failure, is a leak in the hydraulic system.
