How to check the brake hose for leaks and damage in the entire hydraulic circuit on Audi A3?

Check the entire brake hydraulic circuit for leaks and damage, starting with the master cylinder in the engine compartment while also inspecting the vacuum servo unit and ABS units for signs of fluid leakage. Raise the front and rear of the vehicle and support it on axle stands, then examine the rigid hydraulic brake lines for corrosion and damage. At the front, ensure that the flexible hydraulic hoses to the calipers are not twisted or chafing against surrounding suspension components by turning the steering on full lock. Additionally, verify that the hoses are not brittle or cracked before lowering the vehicle to the ground after completing the checks.

How often should you inspect the brake hose connecting the steel brake lines to the brake assemblies, and what steps should you follow during this inspection and replacement process on Audi A4?

Check the rubber hoses that join the steel brake lines to the front and rear brake assemblies once a year with the vehicle in the air and its safe support on jackstands to check the brake lines, cracks, chafing, leaks, blisters, and other damage as this is a very vital part of the brake system. Checking to ensure that there is no weak spot in a hose should also be done using light and mirror and any hose that looks worn should be replaced. In the case of the front brake hose, weaken the wheel bolts, lift the car and take off the wheel. Mark the location of small tabs on the hose fitting into the frame bracket so that they do not rotate. Install the hose fitting with an open-end wrench and install the brake line fitting with a flare-nut wrench to ensure that the nut is not rounded, ensuring that the spring on the hose fitting does not get lost. On the caliper end, a flare nut wrench is required to separate the hose fitting. Take the grommet out of the bracket at the lower end of the strut and push the hose. Installation of the new hose involves attaching the grommet on the hose and feeding it through the strut bracket and attaching the fitting to the caliper and tightening it. When inserting the fitting in the frame bracket, make sure that the hose is not twisted and then connect the line fitting and secure. In the case of the rear brake hose, unscrew the fitting of the hose, take care of the spring clip, and unscrew the hose of the caliper, and replace the sealing washers with new ones during reconnecting. Regarding the replacement of brake lines, genuine steel parts should be used and it is important to make sure that the new line is adequately supported and free of moving parts. Once installed, verify the level of fluid in the master cylinder, apply fluid when necessary and then be sure to bleed the brake system and then test the brakes thoroughly.
