This hose is the same for both left and right sides. It fits buses through Feb. '55. One end has a swivel male fitting, and one end has a swivel female fitting. It's 480mm long, and these are sold individually. Stainless steel is braided around the rubber hose to prevent hose expansion and give a firmer pedal feel. 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.
