  Q: How to replace the front brake line on Chevrolet Avalanche 2500?

  A:

  You need to lift and support the vehicle before removing its tire and wheel assembly. Before installing the rubber cap or plug on the brake pipe fitting end users should cleanse both the brake hose end and brake pipe fitting from dirt particles. Amu up a back up wrench onto the brake hose fitting end and detach the brake pipe fitting end from the brake hose before placing caps or plugs on the brake pipe fitting end. Begin work by removing the brake hose retaining clip from the mounting bracket and then move onto breaking the brake hose bracket bolts from the upper Control Arm and Steering Knuckle and finally remove the brake hose to caliper bolt from the brake caliper. The two copper gaskets of the brake hose must be discarded because they might be attached to the caliper housing or brake hose end. The installation procedure requires positioning 2 new copper brake hose gaskets and the brake hose bolt onto the brake hose before attaching the brake hose to caliper bolt-front and adding 2 new washers to the brake caliper. Tighten the bolt to 40 nm (30 ft. Lbs.) while maintaining the brake hose free from twisting and contacts with suspension components. Place the brake hose bracket bolt onto the Steering Knuckle and upper Control Arm before tightening both bolts to 9 nm (80 inch lbs.). Fasten the brake hose inside the bracket by using the retaining clip. Use a back up wrench on the brake hose fitting end to connect the brake pipe fitting end to the brake hose. Regularly check for any bending of the mounting bracket or brake pipe during installation. Tighten both pieces together to 25 nm (18 ft. Lbs.). Before reattaching the tire and wheel assembly check both extreme right and left turn conditions and bleed the hydraulic brake system. Secure the brake hose away from suspension and tire/wheel assembly with no contact. Check for contact but immediately remove the brake hose to fix the issue before putting the vehicle down.

  Q: How to replace the rear brake line on Chevrolet Avalanche 2500?

  A:

  To replace rear (Caliper) brake hose, raise and support vehicle and tire and wheel assembly. Clean all dirt and foreign matter from brake hose end and brake pipe fitting, and attach a rubber cover or plug on brake fitting end to the exposed brake pipe to prevent brake fluid from losing and contaminating there. Use a back up wrench on the brake hose end to remove the brake pipe end from brake hose and cap/plug the brake pipe end. Take out the brake hose from the bracket, remove brake hose retaining clip from the mounting bracket. Next will be the unpicking of the brake hose caliper bolt from the brake caliper and discarding the 2 copper brake hose gaskets which could be stuck to the brake caliper housing or the brake hose end. For installation, also install 2 new copper brake hose gaskets and the brake hose bolt to the brake hose, then install the brake hose to caliper bolt and 2 new washers to the brake caliper, tightening the bolt to 40 nm (30 ft. Lbs.) and make sure brake hose is not twisted or in contact with any suspension component. Mount the brake hose into the mounting bracket and secure with brake hose retaining clip. Take off the rubber cap or plug from the exposed brake pipe fitting end and join the brake pipe fitting end with the brake hose end using a back up wrench in the brake hose part end without bending the mounting bracket or the brake pipe while tightening the brake hose fitting end end at 25 nm (18 ft. Lbs.). Bleed the hydraulic brake system and reinstall the tire and wheel assembly getting the brake house free from touching parts of the suspension and the tire/wheel assembly. If it does so, then it is necessary to remove the brake hose and fix the condition before lowering the vehicle.
