How should you replace the brake line to prevent brake system failure on GMC Terrain?

Brake pipe failure risks can be avoided by using double-walled steel brake lines with correct mounting at original fastener locations. At service time examine the damaged area before freeing the brake pipe holders and pick an appropriate position for sectioning that should not use bends or clamp points. For the replacement ensure you add the needed flare length which is 0.250 in for 3/16 in pipe, 0.374 in for 1/4 in pipe and 0.499 in for 5/16 in pipe. Use the J-45405 (Pipe Flaring Tool Kit) pipe cutter to cut the brake pipe into your exact measurement. Remove the sectioned piece from the piece. Take the right size brake pipe along with correct tube nuts before removing nylon covering from the flare end. Use de-burring tool J-45405 to cut the inside and outside taper. Place the correct tube nuts on the brake pipe and clean both parts before inserting the dies into J-45405. Position the prepared pipe tip inside dies and screw while fitting the forming rod to produce the flare at 6.74-7.10 mm for 4.76 mm (3/16 in), 8.57-9.27 mm for 6.35 mm (1/4 in), and 10.42-10.79 mm for 7.94 mm (5/16 in). Shampoo the pipe and forming tool before bending. Set up enough space between pipe and moving parts at 19 mm or 3/4 inch. Install andthalmic-flared ends with appropriate connectors safely. Secure brake pipe clips if you removed them before continuing to set up hydraulic brakes. Drain air from brake lines and check the pipe flares for leaks using brake pressure with running engine power.
