How do you replace brake lines?

You probably can get by without a bender. You must use steel lines (available in different lengths at any auto supply store) and you must double flare the ends (the lines that you buy will be double flared on each end - but it is common to have to cut a line or two for the proper fit and routing).

ALWAYS use a union to join the lines when necessary - NEVER use a compression fitting or copper tubing.

You will need a tubing flaring tool with double flaring adapters and a tubing wrench or two (usually 3/8" and 7/16"). Route the lines as close to the original routing as possible to prevent any chaffing, road hazard damage or interference with the normal travel of the suspension components.

Replacing rusted and corroded brake lines on older vehicles, especially in areas where salt is commonly used on the roads in winter, is a very common repair.

you will need line wrenches and a line bender. take the old line off and watch you don,t get it out of shape, lay the old line down against a new line and put the bends in it like the old lines has then install the new lines. as for the cutter, most lines come with fittings and you don,t need to cut them, just join 2 lines together.
