When replacing the steel brake pipes, always use steel piping which is designed to withstand high pressure, resist corrosion and is of the same size.


CAUTION

Be sure to install the correct pipe fittings onto the tube before forming any flares.

    1. Using the Flaring tool NO. J-23530, J-29803 or equivalent, follow the instructions equipped with the tool to form double flares on the end of the pipes.
    2.
