Audi A6 quattro Braided Brake Lines: Are They Worth It?

Brake lines are one of those upgrades that are easy to oversell. They can improve how the brake pedal feels, but they do not turn a stock braking system into a big-brake kit. For the Audi A6 quattro, the more useful question is whether the upgrade matches your goal and whether the kit actually fits your exact version.

Why the exact Audi A6 quattro version matters

The catalog does not treat every Audi A6 quattro as one identical application. Production period, drivetrain, body style or engine version can separate one kit from another.

For the owner, this is useful rather than complicated: match the car’s year and configuration first, and use the part number only after the application itself matches.

Which Audi A6 quattro brake-line kit fits?

Here are the supplier applications that matter when choosing a kit for this car.

Important: use this as a fitment guide, not as a substitute for checking the current supplier listing before ordering.

What braided brake lines change on the road

A braided hose does not give the Audi A6 quattro a larger rotor or more
tire grip. Its job is much narrower: reduce expansion in the flexible
part of the hydraulic system. The result can be a firmer, more
consistent brake pedal, particularly as braking effort and temperature
increase.

For a street car, that usually means better pedal feel rather than a
dramatic reduction in stopping distance. If your main problem is weak
initial bite, pads may make a bigger difference. If the pedal gets soft
after repeated braking, fluid condition deserves attention too.

Why the Audi A6 quattro has more than one kit reference

The important point is not that there are several product listings.
It is that the supplier separates the Audi A6 quattro into different
applications instead of treating every version as interchangeable.

SAU0514-4C

In the fitment listings we reviewed, this reference appears with
Audi A6 quattro 1.8 Turbo, Audi A6 quattro 2.4.
The represented production period is
1999–2005, 1999–2003.
That makes the reference useful only after the car’s version and year
have been matched.

SAU0700-4C

In the fitment listings we reviewed, this reference appears with
Audi A6 quattro 2 Import, Audi A6 quattro 2.5 TDI.
The represented production period is
1994–1997, 1995–1997.
That makes the reference useful only after the car’s version and year
have been matched.

SAU0513-4C

In the fitment listings we reviewed, this reference appears with
Audi A6 quattro 2.4 To Ch 4F-7-03C8-000.
The represented production period is
2005–2011.
That makes the reference useful only after the car’s version and year
have been matched.

If two references appear for your model, start with the exact version
and production year. Do not choose a kit simply because the product
title contains the car’s model name.

When this upgrade makes sense

Braided lines are easiest to justify when the original hoses are aging,
the brake system is already being refreshed, or the car is driven hard
enough that consistent pedal response matters. They also make sense as
part of a complete service with fresh brake fluid.

If your Audi A6 quattro is a lightly driven street car with healthy
factory hoses, there is no need to treat this as a mandatory first
modification. Pads, fluid and tires may deliver a more noticeable
improvement depending on what you are trying to fix.

Installation: what matters more than the brand name

Brake hoses are safety-critical. The correct hose must have the right
length, fittings and routing for the exact application, and it must not
rub, twist or stretch as the suspension and steering move.

Replacing a hose also opens the hydraulic system, so the brakes need to
be bled correctly afterward. If you are not comfortable checking the
routing and finished pedal feel, use a qualified workshop.

TorqueBrief verdict

For the Audi A6 quattro, braided brake lines are a worthwhile
supporting upgrade when your priority is pedal feel and consistency.
They make even more sense when the original hoses are old or the brake
system is already being serviced.

They are not a shortcut to dramatically shorter stopping distances,
and fitment matters. Use the exact version and production period to choose between the available references.

FAQ

Why are there multiple brake-line references for the Audi A6 quattro?

Because the supplier separates different versions or production periods. Match your exact vehicle before choosing the reference.

Will braided brake lines make the Audi A6 quattro stop faster?

Not necessarily. Their main benefit is pedal consistency. Tires, pads,
temperature and road grip have a much larger influence on actual
stopping distance.

Do the brakes need to be bled after replacing the hoses?

Yes. Changing a flexible brake hose opens the hydraulic system, so the
brakes must be bled correctly before the vehicle is driven.
