How to replace the brake line using the J 45405 Brake Line Flaring Kit on 2009 Chevrolet Cobalt?

Question

Accepted Answer

The J 45405 (Brake Pipe Flaring Kit) should be used to replace the brake pipe while also adhering to safety protocols involving brake fluid irritants and paint and electrical component protection. When replacing pipes choose two-wall steel because this will prevent system failures and follow proper methods for fastening and routing the new pipes. Start by checking the brake pipe replacement area then remove any retainers that clash with your work. Select a sectioning spot for the J 45405 pipe that provides enough clearance while ensuring you avoid both bends and mounting points. Begin by measuring the length of replacement pipe while including appropriate flare length based on the following dimensions: 6.35 mm (0.250 in) for 4.76 mm (3/16 in) diameter pipe or 9.50 mm (0.374 in) for 6.35 mm (1/4 in) diameter pipe. A flare length of 6.35 mm (0.250 in) works with 4.76 mm (3/16 in) diameter pipe and 9.50 mm (0.374 in) works with 6.35 mm (1/4 in) diameter pipe. Cut the pipe into the measured length by using the pipe cutter from J 45405 before removing the sectioned pipe. Choose the suitable brake pipe and tube nuts while removing the nylon coating at the flaring end with a blade from J 45405 correctly selected for the operation. Clean debris off the pipe before chafing its ends using the kit's de-burring tool and adding the tube nuts. Insert the prepared pipe end into the die cage while loosening the die clamping screw and placing the die halves correctly into position. Use the J 45405 lever along with the forming mandrel while continuing to tighten the clamping screw to produce the flare. Complete the procedure by using the finishing cone before removing the dies for a diameter and shape evaluation of the flare. 6.92 mm (0.272 in) along with a tolerance of 0.18 mm (0.007 in) needs to be achieved for 4.76 mm (3/16 in) diameter pipe while 8.92 mm (0.351 in) with a tolerance of 0.18 mm (0.007 in) must be achieved for 6.35 mm (1/4 in) diameter pipe. Use the old pipe section as a template to create the new pipe shape before installing the appropriate unions and retaining the pipe then bleeding the hydraulic system. After engine start review the system for fluid leaks while using support for brake application.
