• Q: How to replace the brake line using the J 29803-A ISO Flaring Kit on 2003 Cadillac DeVille?

  A: When replacing its brake pipe, have a use of J 29803-A ISO Flaring Kit (J 29803-A) and make sure that you always use double-walled steel brake pipe for avoiding the brake system failure. Start by getting the right size pipe and steel-fitting nuts depending on the outside diameter of the pipe. Cut the pipe square and of the right length by using a tube cutter, moving it slowly in turns without applying much pressure. Cut the line to the length obtained before, considering 3.2 mm or 0.125 inch per ISO flare. Mount the fittings prior to flaring, chamfer the inside and out diameters of the pipe using a de-burring tool and dispose of all the lubricating materials from the brake pipe and the J 29803-A. Install the J 29803-A to a vise, pick the correct size collet and form mandrel that corresponds with the size of the object pipe and load the mandrel into the J 29803-A while following a probable path. Put the forcing screw into the thread until it touches the mandrel and then turn it back once full turn. Slide the clamping nut over the brake pipe, insert the prepared pipe into the collet finding about 19 mm (0.750 inch) pipe ends protruding, and make sure the pipe ends are touching the face of the mandrel . He could hear the sounds of activities - the tearing leaflets as typewriters struck at a key, the day's newspaper pages being rolled into a pile, and the crunching and snapping of newspaper wrappings in the wastebasket. Wrench tighten the forcing screw until it bottoms, then back out the clamping nut and disassemble the clamping nut and collet assembly. Take measurements of the flare diameter, which should be between 6.92 mm to 7.28 mm (0.272 inch to 0.286 inch), and make the new pipe bend with the aid of a tube bender, ensuring that it matches the old pipe with a minimum 19 mm (0.75 inch) off the moving components, a minimum 13 mm (0.50 inch) off the vibrating components, and 7 mm (0.25 inch) off any shielded lines unless clipped to a component.
