  Q: How to replace the front brake line on Buick Terraza?

  A:

  In order to change the front brake hose, lift and secure the vehicle and take off the tire and wheel assembly. Clean any dirt off the brake hose and brake pipe fitting and fit a rubber cap or plug to the exposed brake pipe fitting to prevent loss of fluid and contamination. Unscrew the brake pipe fitting of the brake hose with the help of a flat-bladed tool in order to remove the brake hose retainer from the brake hose. Next, pull the brake hose off of the brake hose bracket and the brake hose bolt off of the brake caliper and then unhook the brake hose from the brake caliper . Throw away the two copper brake hose gaskets which attach to the brake caliper or brake hose end and insert a rubber plug in the brake hose bolt opening in brake caliper to keep from losing fluid. Remove the rubber remove and install new copper brake hose, gaskets then reassemble brake hose bolt with the new gaskets onto the brake hose. Tighten the bolt to 54 nm (40 ft. Lbs.) and make sure the brake hose is not twisted or kinked, placing it in the position of the notch of the brake hose bracket. Connect the brake hose to the bracket and slide it with brake hose retainer. Take off the rubber cap/extensions from the brake pipe fitting end and attach the brake pipe to brake hose, tightening it to 21 nm (15 ft. Lbs.). No acceleration should be made after the pedal is pulled even with little resistance by pulling rather, it should provide a solid brake as too much air left in the brake system can cause braking failure. Bleed brake caliper at the bleeder screw and reinstall the tire and wheel assembly before lowering the vehicle.

  Q: How to Service and Repair the Brake Line Using the J 45405 Pipe Flaring Tool Kit on Buick Terraza?

  A:

  Use J 45405 to work with brake pipes when following all safety instructions related to brake fluid chemicals and double-wall steel pipes for safe repairs. First inspect the defective brake pipe section then free it from the retainers when needed. Take a measurement of the replacement pipe length along with its bends and add flare components. Cut the final end at 90 degrees for smooth flaring. Cut the brake pipe using your J 45405 tool pipe cutter and remove the measured segment from the vehicle. Take brake pipe components that fit the application and use the J 45405 coating stripping and de-burring tools to prepare ends for flaring. Clean all parts of the brake pipe and J 45405 before proceeding with the flaring process. Place the ready pipe into the dies and secure them with the clamping screw while forming a flare through the mandrel action. Inspect the flare results and adjust new pipe shape if needed. Connect the pipe to the vehicle with correct unions after completing the flare process. After securing brake pipe onto retainers bleed the hydraulic brake system and test for leaks as you press brakes with running engine.
