brakes on 1995 Ford Ranger

brake peddle goes all way tt floor master cilender was low on fluid but can not find out where fluid is going

Asked by for the 1995 Ford Ranger
Sometimes a master cylinders piston will wear out internally and will need replacement also when your pads and shoes wear down to the minimum amount of friction materials the master cylinder will appear low because the brake fluid was forced down the system, better have your brakes checked for leaks and before metal to metal contact if the pads or shoes are worn out

if it's standard check the clutch
