Question: Audi Brake Fluid Type?

What brake fluid does Audi use?

Brake fluids that CAN be used in your Audi or VW:

FMVSS 116 DOT 4 or DOT 5.1 racing brake fluids.

Does it matter what type of brake fluid I use?

YES! It’s very important– the fluid specified by the original vehicle manufacturers must be used. DOT 3 & 4 brake fluid is a mineral based fluid. DO NOT use DOT 5 in a vehicle equipped with ABS (Anti-Lock Brake System).

What type of brake fluid do most vehicles recommend?

By far, DOT 3 is the most popular. It’s been in use for a very long time. Fresh DOT 3 has a boiling point of 401 degrees Fahrenheit, fully degraded it drops to 284 degrees Fahrenheit. This makes your brake fluid much more likely to boil.

Can I use any type of brake fluid in my car?

Check your vehicle’s owner’s manual to see if there are any specific instructions for the type of brake fluid you should use. Also, the cap usually states what kind of brake fluid is required. For the vast majority of vehicles, a standard glycol-based DOT 3 or DOT 4 brake fluid should be used.

Can I drive with low brake fluid?

Low brake fluid or worn brake pads are other reasons your Brake Warning Light may come on. If the brakes are leaking, you will not be able to stop the car. This is dangerous and your vehicle should not be driven in this condition.

What happens if you use DOT 3 instead of DOT 4 brake fluid?

Yes, DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point. DOT 5.1 is used in high-performance and heavy-duty applications due to its high boiling point.

Which is better DOT3 or DOT4?

Most applications call for a DOT3 (401F dry/284F wet) or DOT4 (446F dry/311F wet) fluid, which is considered a higher performance fluid since it can handle more heat. While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat.

Should I use DOT3 or 4?

The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you’ll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.

Is all DOT 3 brake fluid the same?

They do differ between DOT spec of course one is silicone, each has a different tenacity for water, and different boiling points. But a few years back there was a to-do with either Honda or Toyota due to incompatibility of seals with fluids that didn’t have their additives.

Is all brake fluid the same?

The three main types of brake fluid now available are DOT3, DOT4 and DOT5. DOT3 and DOT4 are glycol-based fluids, and DOT5 is silicon-based. The main difference is that DOT3 and DOT4 absorb water, while DOT5 doesn’t. One of the important characteristics of brake fluid is its boiling point.

Can you mix DOT 3 and DOT 3 Synthetic brake fluid?

THEY’RE ALL FULL SYNTHETIC! It’s Silicone brake fluid, not synthitic fluid that can‘t be mixed with other types of brake fluid. The different types of brake fluid is the difference between synthetic and silicone not synthitic and non synthetic. There is not such thing as DOT 3 regular fluid and DOT 3 Synthetic.

How much does brake fluid cost?

Generally, a brake fluid flush costs around $100, with most of that cost going towards labor. Brakes are arguably the most important system on your car, next to the engine itself. Over time, the components of your brake system wear down.

Can you mix old and new brake fluid?

Brake fluid is prone to absorbing water, which is one of the reasons you replace it. You CANNOT reuse fluid, and you CANNOT mix old with new.

Do you pump brakes after adding brake fluid?

Step 6: Pump the brakes.

Top up the brake fluid in the reservoir after every interval of pumping the brakes. The brake fluid change is complete when the fluid looks new in the brake bleeder hose.

What happens if you use the wrong brake fluid?

Nothing bad will happen to the brake system itself. DOT 3 and DOT 4 are compatible. However, DOT 4 has a higher boiling point than DOT 3. That your car requires it suggests its braking system will be worked hard enough to boil DOT 3 brake fluid.
