• Q: How to properly replace brake lines to ensure system integrity on 2010 Buick Enclave?

  A: Use double-walled steel brake pipe when replacing pipes to avoid brake system failure and stabilize the routing by using original position fasteners. When sectioning brake pipes arcuate a replacement pipe with matching dimensions and adopt correct fittings that parallel the original blueprint. The first step involves examining the portion of brake pipe that requires treatment then freeing it from any retainers when possible before identifying an area for pipe sectioning at least one inch wider than the size of the J 45405 Pipe Flaring Tool Kit. Determine the replacement pipe length for the area to be fixed and include flare extension measurements according to the following specifications: 6.35mm(0.250in)for4.76mm(3/16in)dia-meterpipe, 9.50mm(0.374in)for6.35mm(1/4in)dia-meterpipe, 12.67mm(0.499in)for7.94mm(5/16in)dia-meterpipe. The required length for flaring measures 6.35 mm (0.250 in) for 4.76 mm (3/16 in) diameter pipe and 9.50 mm (0.374 in) for 6.35 mm (1/4 in) diameter pipe and 12.67 mm (0.499 in) for 7.94 mm (5/16 in) diameter pipe. Lay the brake pipe straight on the J 45405 pipe cutter to achieve the precise length before extracting the piece and picking the suitable brake pipe alongside tube nuts. Use the proper blade on the J 45405 coating stripping tool to remove nylon coating from brake pipe ends while protecting the metal surface. Use the de-burring tool from the J 45405 to chamfer both external and internal pipe diameters before adding the tube nuts to clean off all materials from this area and from the tool. Introduce the prepared pipe end through the dies until it reaches the fully seated position while using the appropriate die set on the J 45405. Use the J 45405 lever to form the pipe following selection of the proper forming mandrel after screwing down the clamping mechanism. Perform this process one more time by choosing the finishing cone. Examine the flare's shape and diameter after you take out the dies: For pipe diameters of 4.76 mm (3/16 in) the flared end should be between 6.74-7.10 mm (0.265-0.279 in) and 8.57-9.27 mm (0.344-0.358 in) for 6.35 mm (1/4 in) ends and 10.42-10.79 mm (0.410-0.425 in) for 7.94 mm (5/16 in) ends. New brake pipe installation requires using a brake pipe bending tool to shape it before inserting the pipe with appropriate unions into retainers and running hydraulic system bleed procedures then inspecting finisher flares for leaks under engine operation with activated brakes.
