What Brake Fluid Do I Need For BMW 1 Series?

500ml of Motul DOT 5.1 brake fluid.

Hello everyone, I need to know what kind of brake fluid is used by the OEM since I will shortly be performing the CDV deletion. any specific type and brand.

I hesitate to purchase store brands (such as Advance or Auto Zone), but I also don’t want to purchase uber-racing gear like motul or the like. I want something of decent OEM quality.

Any DOT-4 brake fluid is OK. However, I would choose one in a different color. Any DOT-4 brake fluid, including ATE-SL, will work. Even your dealer may sell you some fluid. ! L is going to be plenty.

What I used in Germany is seen here. However, I don’t believe you will locate it in the United States.

Check out my work in this “CDV delete DIY” thread, specifically posts 97 and after.

For track work or really high performance, use ATE Type 200 or Pentosin Racing Brake Fluid.

Keep in mind that ATE Super Blue is the exact same item as ATE Type 200, just with different packaging.

I personally dislike the blue color because it turns everything blue, including the

Blue brake fluid aids race teams by protecting their hands, my Vacula brake bleeder, and the reservoir.

It only serves one purpose, in my opinion, which is to locate the source of leaks in race vehicles.

For BMWs, such as the xDrive models, that require low viscosity brake fluid, ATE SL.6, or Pentosin LV is advised.

Super Blue not only helps racing teams, but it also informs the dealer (BMW) that you are using aftermarket brake fluid, which is bad if your vehicle is still covered by a warranty.


a high-quality brake and clutch fluid that satisfies and surpasses the most recent international standards U.S. The normal dry boiling point is 271 degrees Celsius, and the typical wet boiling point is 169 degrees Celsius, according to FMVSS No.116, DOT 3 and DOT 4, SAE J1703, and ISO 4925.

What type of brake fluid does BMW advise?

BMW brake fluid should be either Normal or Low Viscosity and DOT4, DOT5, or DOT5.1 rated. Low Viscosity fluid is used on any BMW model equipped with Dynamic Stability Control (DSC), which includes nearly all BMWs since 2003, unless the vehicle is being driven on a racetrack. The thicker Normal Viscosity fluid is used for track use and in vehicles without DSC. Although some DOT4 fluids could also be low viscosity, all DOT5.1 fluid is.

The fluid’s dry and wet boiling temperatures are described by the DOT ratings. Wet fluid has absorbed moisture after a year, whereas dry fluid is still fresh out of the bottle. A higher DOT rating is earned by having higher boiling points. However, DOT5.1 is only used for low viscosity glycol-based fluid, while DOT5 is related with silicone-based fluid. Labeled as “DOT4/5” or “Super DOT4”, a Normal Viscosity fluid that satisfies DOT5 boiling points is classified. Although DOT3 fluid can be utilized in a pinch, DOT4/5 is preferable because to its higher boiling points.

Under non-racing conditions, glycol-based fluid (DOT3, DOT4, and DOT5.1) should be flushed/changed every one to two years; however, for track or racing use, this frequency should be substantially higher.

What shade is the braking fluid in BMW?

Brake fluid has a yellow hue and is translucent (clear). Therefore, if you gaze into the reservoir, you ought to be able to see the bottom and it ought to appear somewhat yellow.

What is the lifespan of BMW brake fluid?

The standard recommendation is to replace your brake fluid every two years. Moisture can enter the brake fluid even while your BMW is parked in a garage and not being used, which can result in brake failure.

When should the brake fluid in a BMW be replaced?

When ought my brake fluid to be changed? – The majority of manufacturers recommend flushing the brake fluid every two years, however there are other indications that your brakes require maintenance.

With black brake fluid, is it safe to drive?

You should avoid using brake fluid that is black since the color suggests that it has likely absorbed a significant amount of impurities and moisture. This is done on purpose because you don’t want moisture at the caliper end to turn into brake fluid that boils at 100 degrees Celsius.

If you let it deteriorate, though, the moisture may wind up corroding metal parts in your braking system, causing damage. This only portends several issues in the future.

Can I change my own brake fluid?

The first step in learning how to change brake fluid is to remove the old fluid from the reservoir and replace it with new fluid.

Some automakers advise changing brake fluid every 24,000 miles or every two years. Others fail to mention changing brake fluid at all. However, checking your brake fluid is simple. To check the color, simply dip a test strip into the fluid and match it to the chart on the container.

Although you can’t perform a thorough brake fluid cleanse yourself, you can perform a fluid switch. You won’t completely replace the old fluid with new fluid during this treatment, but you will add enough new fluid to notice a difference.

What occurs if brake fluid is not changed?

The brake reservoir, where the brake fluid is housed, will become contaminated with moisture if you don’t change your brake fluid as advised by the vehicle’s manufacturer.

Your braking fluid will inevitably become polluted with “debris buildup” as it ages. Your brake system’s many seals and hoses might gradually lose little amounts of rubber as they wear down. Additionally, rust particles may get up in your brake fluid as a result of metal components corroding and rusting due to moisture-rich brake fluid.

Your car’s ability to stop suffers substantially from not changing the brake fluid, which results in subpar braking performance. Most of the time, you can tell by pressing the brake pedal: if it feels excessively spongy, your brake fluid is probably about to fail. You may find that stopping your car requires more work and time, and in some situations, you may even need to pump the brakes in order to build up enough pressure for a secure stop.

If you’re moving at any speed, the uncomfortable idea that your brakes could completely fail is also a deadly one. This may occur if the boiling point of the braking fluid is reached while the vehicle is in motion, particularly if the boiling point was intentionally decreased due to moisture contamination.

How much does it cost to change the brake fluid?

In general, the price of changing brake fluid can range from $80-$120. For most car makes and models, the price is comparable. Brake fluid is a low-cost product. Labor makes up the bulk of this expense. Therefore, if you are a DIYer and have the necessary skills. On Amazon, you can get a reliable brake fluid flush kit. There are also lots of educational YouTube videos that can show you how to flush your brake fluid.

When you bring your car to G&G for servicing, we check the brake fluid for contaminants and, if necessary, recommend replacing it. Your automobile or truck may be safer to drive and will require fewer repairs in the future if you use fresh brake fluid.

How can I tell if my brake fluid needs replacing?

Typically, brake fluid is a clear, pale tint. If it isn’t clear or clean, your brake fluid has to be changed since it is soiled. If the brake fluid drops below the “full line” marking on the reservoir, it’s a sign you need to replace your brake fluid or top it off.

Which brake fluid should I use, DOT 3 or DOT 4?

brake fluid DOT 4. The main distinction between the two is that DOT 3 brake fluid will require less frequent fluid changes since it will collect less water from the air than DOT 4 over time. Due to its higher dry and wet boiling points, DOT 4 brake fluid is more heat-resistant.

Can you add brake fluid on your own?

  • Put your car in a level spot.
  • If the brake fluid reservoir cap is dirty, clean it to prevent debris from getting into the reservoir.
  • Take off the cap. You may need to have brake fluid changed at a shop if the fluid is particularly black or contains debris because it may be past its expiration date.
  • Brake fluid should be cautiously and gradually poured into the reservoir until the maximum fill indication is reached.
  • Screw the reservoir cap back on firmly.
  • Once parked on a flat surface, drive your car for a short while, sometimes braking, and then check the fluid once again to make sure the fill was successful.

Avoid spilling brake fluid on your car or the engine bay since it might damage paint. If you do, wipe it off thoroughly with water. Because it is oily, you can tell when the surface is completely clean.

Dot4 brake fluid: what is it?

A cutting-edge, high-performance, premium brake fluid of exceptional quality, BRAKE FLUID DOT 4 has a high wet boiling point and, as a result, an extremely high safety reserve against vapour lock. For hydraulic disc brakes and drum brakes on motorcycles, cars, trucks, and other vehicles, BRAKE FLUID DOT 4 is the best choice.

Which one, DOT 3 or DOT 4, is thicker?

Both are formed of glycol ethers, but DOT 4 braking fluids have increased dry and wet boiling points because to the addition of borate esters. The maximum viscosity requirements for DOT 4 are likewise marginally greater than those for DOT 3.

What happens if DOT 3 and DOT 4 are combined?

Yes, you can combine Dot 3 and Dot 4 brake fluid. Because both of these brake fluids are glycol-based, they are compatible with one another. It is not advised to fill your automobile with Dot 3 if it came with Dot 4 from the manufacturer, however the other way around is acceptable.

If your vehicle came equipped with Dot 3 and you frequently tow a trailer or drive up steep slopes, we strongly advise replacing it with Dot 4.

Can DOT 3 and DOT 4 be combined?

Can DOT 3 and DOT 4 be combined? This is what? Since DOT 3 and DOT 4 brake fluids are both glycol-based, mixing them is not a problem, but you should be aware that the boiling points will alter. DOT 3 and/or DOT 4 brake fluid should not be mixed with DOT 5 brake fluid because the latter is silicone-based.

Can DOT 5 be substituted for DOT 4?

Today’s most well-liked vehicles on the road use silicon-containing DOT 5 braking fluid. The increased price is due to high boiling points. It reaches its boiling point at 260°C dry and 180°C wet.

Modern brake rotors are often thin and compact, which improves heat dissipation. For this kind of technology, silicon-based braking fluid is suitable since it can withstand high temperatures.

High-performance automobiles benefit greatly from using DOT 5 brake fluid because it does not absorb moisture and has no negative effects on painted surfaces. The braking system is shielded from the impacts of severe weather while using this brake fluid.

Although DOT 5 can be used in place of DOT 3 and DOT 4, it must never be combined with any other brake fluid.

Brakes made of silicon are more difficult to bleed. DOT 5 brake fluid-filled brake systems, however, are more rust-resistant and last longer than those utilizing other formulations after bleeding.

The fluid’s performance is unaffected by cold temperatures because of its light nature. The viscosity of DOT 5 is much more stable in extreme temperatures.

Additionally, there are significant drawbacks to utilizing DOT 5 brake fluid. It expands significantly when heated, and the chemicals may evaporate, giving the food a more spongy feel.

This fluid is incompatible with systems that have previously used glycol-based fluids unless you flash it and replace the seal. Since silicone fluids are thicker, anti-lock brakes are also incompatible with them. Unlike glycol fluids, which start to compress when they reach their boiling points, silicone brake fluids start to compress at temperatures between 150 and 180 degrees Celsius.
