How to replace the rear brake line on GMC Acadia?

When replacing a rear brake hose you need to start by raising and supporting the vehicle before removing the tire and wheel ensemble. Using a back up wrench on the brake hose fitting you should disconnect it after first cleaning the brake pipe fitting and using a cap to prevent fluid loss. After removing the brake hose bracket bolt and brake hose fitting bolt you should discard the two brake hose fitting gaskets before taking off the brake hose. Position the new brake hose before installing two new brake hose fitting gaskets. Use a 40 N.m (30 lb ft) torque while installing the brake hose fitting bolt and then use 12 N.m (106 lb in) torque when tightening the brake hose bracket bolt. Use a back up wrench to tighten the brake pipe fitting at 17 N.m (13 lb ft). Complete a hydraulic brake system bleed then replace tire and wheel components before lowering down the vehicle.

How to Service and Repair Brake Lines Using the J 45405 Pipe Flaring Tool Kit on GMC Acadia?

Use a J 45405 Tool Kit (J 45405) to repair brake pipes by ensuring you use double-walled steel brake line so the system does not fail. Before starting you need to examine the damaged brake pipe section and free it from retaining hardware when needed. Pick a recommended spot to cut the brake pipe and stay clear of bends or mounting points. Then measure the broken pipe span including the added flare dimension of 6.35 mm for 4.76 mm pipes and 9.50 mm for 6.35 mm pipes. You should use the J 45405 pipe cutter to make square cuts across the brake pipe then take away the divided piece. Choose the suitable brake pipe sizes and tube nuts before using the coating stripping tool and de-burring tool from J 45405 (J 45405) set to prepare the flaring end. Place tube nuts on both ends while clearing dirt from the brake pipe and J 45405 tool before unlatching the die clamping screw. Place the correct die set into the die cage before inserting the prepared pipe and operating the lever of J 45405 to create the flare. Ensure the flare matches 0.265-0.279 inch for a 3/16 inch pipe and 0.344-0.358 inch for a 1/4 inch pipe. Then adjust the new pipe with a bending tool when required and attach it correctly with unions and retainers followed by hydraulic brake system bleeding. Use a leak test to find any problems with brake pipe flares when the engine runs and brakes engage.
