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.

Audi A4 Brake Hose

The Audi A4 Brake Hose transmits the master cylinder's pressurized brake fluid to each caliper, providing the driver with firm and predictable braking power when they step on the pedal. Each Brake Hose, installed inside the hydraulic circuit, has the ability to flex with the movement of the wheel but seals the system to prevent leaks of fluid. The development of cracks or leakage in the hose will make the pedal feel spongy, and the total braking distance will increase. The wet spot, bulge, or abrasion can be caught on visual inspection before causing any trouble, so that a worn Brake Hose can be replaced before safety becomes jeopardized. The first generations of the A4 model applied rubber hoses, which are very light weight and inexpensive, but rubber hoses can swell as a result of high hydraulic pressures, taking some of the force that you are applying to the discs. Subsequent fans and even factory performance packages of Audi models shifted to stainless steel braided Teflon designs that do not expand, providing a more solid pedal action with less travel. Both types can be applied in the same mounting holes, but the braid will provide a durable outer shell that shakes off heat and debris, so it will be the style of choice for the driver who wants the maximum braking ability out of the Audi. No matter the year of construction, the car has four hoses, two in the front and two in the back, and they are replaced with care, bleeding them without letting air get into the closed Audi system. Vigilance over pedal performance and regular checks will make sure that any faulty Brake Hose is changed at the initial stage, maintaining the creditable braking qualities that have been pivotal in the Audi.

Audi A4 Brake Hose Parts and Q&A

Brake Line
4F0-611-721-C
Q: 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?
A:
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.
