1984-1989 Nissan 300ZX / 280ZX Brake Hose Modification Page
Click any picture to see an enlarged view.
Go to auto parts store, junk yard, parking lot (watch out for owner) and get a front brake hose from a 280ZX. Side and year do not matter, they are all the same. To be less confusing, ask for the driver's side front brake hose for a 1982 280ZX. This is the rubber hose that goes from the brake caliper to the hard line. Probably be a good time to buy some more brake fluid as you will have to bleed the system when you are done.
