The flexible hoses that connect the steel brake lines to the front and rear brakes should be examined every six months to check for evidence of cracking, chafing of the outer cover, leakage, blistering, and damage. Replacement steel and flexible brake lines can often be found at dealer parts departments and auto parts stores. Always use only genuine steel lines or approved flexible brake hoses as replacements. While installing the brake line, ensure that there is at least 0.75 inch (19 mm) clearance with all moving and vibrating parts. To separate the hose and line, first, remove the spring clip, after that use a normal wrench to hold the hose and a flare-nut wrench to hold the tube for disconnection. Use the identical wrenches for connecting and installing a new clip, making sure that the tube passes through the center of its grommet. When disconnecting two hoses, use ordinary wrenches on the hose fittings. When connecting, make sure they are not bent, twisted or strained. Steel brake lines usually have clips that retain them along their length. Prior to removing a fixed brake line, all of these clips must be completely removed. After installing the brake line, you should reinstall these clips or new ones if they are damaged. The clips keep the brake line in place and prevent any vibrations that may cause a breakage. Ensure hydraulic system bleeding takes place when removing hose or tubing (if applicable).
