How often should you inspect the Brake Hose connecting the steel brake lines to the brake assemblies on Mazda 6?

Open the vehicle, raise it up, and place on jackstands, approximately every six months, the flexible hoses between the steel brake lines and the front and rear brake assemblies; check them with regards to cracks, chafing, leaking, blistering, etc. as these are vital components of the braking system. A light and a reflecting mirror will also help in a complete check and a defective hose must be taken out and replaced with a new one. The first step is to make the ends of the hose clean, after which a flare-nut wrench is used to unscrew the tube nut to prevent rounding off of the corners, and then loosen the bolt(s) or clip(s) holding the hose. In the case of front brake hoses, unscrew brake line fitting and hold the fitting block in place with another wrench, remove mounting bolts and remove the hose on the caliper by unscrewing the banjo bolt. In the case of rear brake hoses, use the pliers to hold the bracket, then deattach the clip and the hose of the caliper. Disconnect hose to caliper, unscrew the sealing washers and screw the new brake hose in place with new sealing washers tightening the banjo fitting bolt to a prescribed torque. Turn the removal process back to fit the hose, make sure it is not twisted and make sure this hose does not come into contact with the suspension or steering parts and have an assistant push down on the vehicle and turn the steering wheel lock-to-lock as part of the inspection. When changing brake lines, it is important to use the right parts and never use copper tubing and buy steel brake lines at the dealer or auto parts store. Ready-made brake lines that have flared ends and fittings are offered and can be bent with a tubing bender to the required shapes. Make sure that the new line is securely held in place in the brackets with plenty of clearance of moving or hot objects. Once installed, verify the level of the master cylinder fluid, fill it, and Bleed the brake system, test the brakes thoroughly, and put the vehicle back into normal operation.
