This hose is the same for both left and right sides. One end has a male fitting, and one end has a female fitting. It's 350mm long, and these are sold individually. These are stock replacements for Ghias and Type-3s that originally came with disc brakes. These are also for use with most Beetle disc brake upgrade kits. After years of use, rubber brake hoses can collapse from the inside, which restricts fluid from leaving the wheel cylinders and causes the brakes to drag. Sometimes they can look fine from the outside, but still need to be replaced.
