  Q: How to replace the front brake line on a with RPO LNF (2.0L) on Chevrolet Cobalt?

  A:

  A vehicle owner must lift and stabilize their vehicle during front brake hose replacement when working on vehicles with RPO LNF (2.0L). Start by taking out the tire and wheel assembly from the vehicle. Isolate the front brake pipe fitting by using a cap to stop fluid leakage and stop contaminants from entering. The next step is to remove the front brake hose bracket bolt as well as the brake hose fitting bolt and brake hose fitting gaskets from the brake hose before discarding the gaskets. Remove the brake hose. Brake hose installation requires the brake hose fitting bolt to connect with two new brake hose fitting gaskets installed on the brake hose . Mount the brake hose assembly to the caliper where its brake hose fitting bolt must be tightened to 40 Nm (30 lb ft). Next install the front brake hose bracket bolt while applying torque to 25 Nm (18 lb ft). Fit and snugly tighten the front brake pipe fitting to 19 Nm (14 lb ft). Use the correct procedure to bleed the hydraulic brake system. The last step is to put on the tire and wheel assembly.

  Q: How to Service and Repair Brake Lines Using the J 45405 Brake Line Flaring Kit on Chevrolet Cobalt?

  A:

  Using the J 45405 Brake Pipe Flaring Kit (J 45405) service and repair brake pipes by selecting double-walled steel brake pipe to avoid brake system failure. Start by examining the designated replacement area of brake pipe while setting free retainers which secure it in place. When cutting the brake pipe choose a proper spot which is far from bends and mounting points. Measure the length for pipe removal and include flare dimensions that correspond to 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. These values apply: 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. You should use the J 45405 (J 45405)'s pipe cutter to make a square cut on the brake pipe then discard the sectioned pipe. Use the correct brake pipe and tube nuts then remove the nylon coating from the flaring section using the coating stripping tool parts of the J 45405 (J 45405) before creating consistently sized inside and outside edges with the de-burring tool of J 45405 (J 45405). Before installation clean both brake pipe and J 45405 (J 45405) from all contaminants. Then loosen the die clamping screw of the J 45405 (J 45405). Put in the suitable die set followed by inserting your prepared pipe end before leveraging the J 45405 (J 45405) for the flare-making process. Check the flare dimensions after formation to confirm proper size and shape-6.92 mm (0.272 in) diameter within 0.18 mm (0.007 in) tolerance for 4.76 mm (3/16 in) pipe and 8.92 mm (0.351 in) diameter within 0.18 mm (0.007 in) tolerance for 6.35 mm (1/4 in) pipe. Then proceed with installing the new pipe to vehicle retainers along with appropriate brake pipe unions before bleeding the hydraulic brake system. Test for brake pipe leaks by running the engine and applying the brakes.
