Pentosin DOT 4 Brake Fluid, 1 Liter, SKU 579851, Part Number PENT1204116 (29)
Pentosin DOT 4 brake fluid, Prestone 12 ounce DOT 4 brake fluid, and Prestone 32 ounce DOT 4 brake fluid are recommended for the 2011 BMW 328i.
Breathing fluids
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.
On a BMW 328i, where is the brake fluid reservoir?
On the driver’s side, the brake fluid reservoir is located below the plastic cover. To access the reservoir, you must remove the plastic top.
What kind of brake fluid is required for a BMW?
It’s time for my two-year brake fluid flush, and because the car is no longer covered by a warranty or maintenance plan, this is the first time I’ll be doing it myself.
It’s an everyday driver. During rush hour, the interstate traffic is frequently stop-and-go. On the track never.
My concern is: For better protection, should I stick with the stock BMW brake fluid or should I swap to another brand? Or would it not be required?
DOT-4 brake fluid is used in every new BMW. Sometimes it is difficult to find, or you can only obtain synthetic DOT-3/DOT-4. I purchased some DOT-4 (“Super 4”) under the Pentosin (German) name at a business that sells vehicle parts for imports. A 1L can and a 1/2L can cost me $16.
Many individuals also utilize the ATE brand, specifically the ATE200 or the ATE super-blue (gold colored).
Thanks. I suppose my biggest concern was whether there was any legitimate justification for me to use something other than OEM brake fluid. especially while I’m driving like I normally do. Would using an aftermarket fluid give me any observable benefits?
In a day-to-day driving scenario, there will be no advantage to ANY DOT 4 over another. I’ve used Valvoline DOT3/DOT4 in numerous BMWs for about ten years. Cheap and simple to find (AutoZone).
If you’re not wasteful, one liter or quart should be sufficient. It wouldn’t hurt to purchase two so you have enough for top-off or the next time.
I also concur with this. Currently, I have Valvoline in both my Z3 and E90. I merely desired a change to something different. Since Pentosin is the original equipment manufacturer’s power steering oil, I assumed that their brake fluid would be adequate for the brake system. It wasn’t too expensive either.
I think Castrol LMA is BMW’s OEM. I was told that many years ago by a parts specialist at Tischer BMW, and I used it for my E30 for a very long period.
Under typical driving circumstances, we advise sticking to the authentic BMW fluid (found HERE).
Flushing is made a little bit easier by switching between blue and yellow on the ATE. Although there is nothing wrong with OEM for daily/street driving, ATE’s price is quite reasonable for a high temperature fluid.
Do I need any brake fluid, BMW?
I need to know how many bottles of brake fluid I’ll need because I’m about to clean out my braking system. Does anyone with experience flushing brake fluid know how many liters I’ll require? I’ll also need to bleed out my clutch because I have a 6MT.
Three automobiles can fit in a 3L. For the clutch and perhaps the brakes, 1L should be adequate. See how far you can get with 2L. Also, unless absolutely necessary, avoid opening the second bottle. Even in a closed container, DOT 4 or DOT 5 has a shaky shelf life since it is highly hygroscopic (absorbs moisture). But you already knew that.
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.
When should the brake fluid in a BMW be replaced?
Most manufacturers recommend changing your brake fluid every two years, but there are other indications that your brakes require maintenance.
Should I only add brake fluid?
You don’t need to add any brake fluid if your brake fluid level is at or above the “MIN” line. Once the reservoir cover has been gently removed, add brake fluid until the level is slightly below the “MAX” line if your fluid level is below the “MIN” line. Avoid overfilling.
Is it okay to blend new and old brake fluid?
“Both DOT 4 and DOT 5.1 braking fluids, which are glycol-based, are widely utilized in the automobile and cycling industries. The moniker comes from the fact that they are governed by DOT-established rules.
The boiling points of these two brake fluids are the primary distinction. The minimum dry and wet boiling points are one of the requirements that DOT fluid producers must meet. These are the lowest temperatures that the brake fluid can operate at without beginning to boil, which can result in a complete failure of the brakes.
Let’s look at the Department of Transportation’s recommended minimum boiling temperatures for DOT brake fluid.
Remember that these are merely the basic requirements. It is feasible to find DOT 4 brake fluid with a higher boiling point than other DOT 5.1 fluids on the market, and brake fluid producers frequently do so.
Since DOT 4 and 5.1 are both glycol-based brake fluids, they can be mixed without damaging your brake system because they are compatible with one another. Never confuse DOT 5.1 (a glycol-based fluid) with DOT 5, a silicone-based fluid that must never be used with any other DOT fluid.
Which braking fluids can you actually combine without damaging your brake system, then? Let’s examine the graph below.
The silicone-based DOT 5 is the odd one out in this group and is incompatible with all other DOT brake fluids, as can be shown. The worst that can happen when mixing DOT 3, 4 and 5.1 braking fluids, providing it is new fluid, is a decrease in the boiling point of the entire fluid.
Some brake producers, including Hayes and Formula, ship their brakes with DOT 4 brake fluid already added. Some manufacturers, like Hope and Avid, decide to employ DOT 5.1 in their brakes. In order to take advantage of the higher boiling point and enhanced heat resistance of DOT 5.1, many riders with DOT 4 in their brakes will choose to bleed with it.”
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.
Can DOT 3 and DOT 4 brake fluid 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 brake fluid be topped off without bleeding?
Yes, you can complete this process without bleeding since it is not necessary. Bleeding is not necessary to simply check the liquid level. When you fully empty the reservoir, use the brakes, or detect a leak, you should bleed the system to prevent air bubbles from entering the lines and pipes. To ensure their best efficiency, it is suggested to carry out the procedure once every two to three years.
Can I substitute DOT 3 for DOT 4?
Yes. DOT 3 and DOT 4 brake fluid are interchangeable. DOT 4 has a greater boiling point, though.
Due to its high boiling point, DOT 5.1 is utilized in high-performance and heavy-duty applications. The fluids DOT 3 and DOT 4 are compatible with it.
Because DOT 5 brake fluid is silicone, it does not absorb moisture. It is mostly utilized in vintage cars that are kept in storage for extended periods of time and require a brake fluid that doesn’t absorb water because it is incompatible with the other brake fluids.
