On the more recent non-M models, BMW has extended brake fluid changes out to every three years. The interval was calculated from the time the car was built, not from the time it was sold. They were responsible for two free brake fluid replacements due to the two-year interval and the four years of free maintenance. They are now just responsible for one.
Warping the rotors is a wonderful outcome of pulling over and stopping suddenly. Warping results from the rotor’s underside not cooling as quickly as the rest of the rotor. Utilize engine brakes and avoid getting them too hot in the first place as part of Plan A. Plan B is to move slowly enough to allow them to cool before using them, but quickly enough to ensure that they do not warp excessively.
The fluid boils and the vapor compresses rather of applying force to the brake pads when the brakes are really hot, which is another issue.
The best way to add brake fluid
Changing brake fluid begins with sucking out the dark-brown brake fluid with a baster (brake and power steering fluids are incompatible, so use a different baster for each). Pour it into a bottle for recycling. Fill the reservoir as directed with brand-new brake fluid. Once the fresh fluid has been added, let the car run for a week. Over the following few weeks, carry out the procedure several times more until the liquid in the reservoir keeps its light honey hue.
Don’t completely suck the brake fluid into the rubber bulb of the baster because doing so could harm it.
Which braking fluid is applied by 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.
What occurs if a BMW doesn’t update its brake fluid?
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.
Can I replace the brake fluid on my own?
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.
How frequently should BMW brake fluid be replaced?
Your car’s braking fluid absorbs water over time, which could result in brake failure. To ensure that your brakes perform at their best, vehicle manufacturers advise changing your brake fluid every two years.
Does replacing the brake fluid really need to be done?
It’s a good idea to have your mechanic check your brakes and brake fluid every time you get your oil changed. They’ll be in the greatest position to advise you on the condition of your brakes and whether additional fluid is required. Most motorists discover that their brake fluid needs to be changed every four to five years.
Is it possible to replace brake fluid without bleeding?
To get rid of moisture, every hydraulic brake system needs to be bled and replenished with new fluid. Sucking the majority of the fluid out of the master cylinder with a pump or meat basting tool is an easy way to do this without bleeding. When removing the fluid, take care to avoid exposing the circuit to air.
How much does it cost to change the brake fluid?
To ensure safety, changing the brake fluid or performing a brake fluid flush should cost between $80 and $130 and be carried out by a qualified mechanic.
Depending on the sort of fluid you have and whether you want to change it yourself, these expenses may fluctuate. Brake fluid generally costs between $6 and $39 per quart, mechanics bill between $150 and 210 per hour, and changing the brake fluid in the majority of cars would set you back on average $100.
Can old and fresh brake fluid be combined?
“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.”
Do I need to replace my brake fluid after 100,000 miles?
- Stoppers, brake hoses, lines, and connectors
- Check the air pressure and rotate your tires.
- exhaust mechanism
- every liquid level
- Drive shaft, drive belts, seals, and boots
- Fuel hoses, couplings, and lines
- tie rod ends, suspension, and steering.
In addition to contributing to steering issues, suspension and steering issues hasten tire wear. By making sure your shocks are examined by a professional and that your steering fluid is updated, you may prevent these issues.
Your transmission fluid, oil, coolant, power steering fluid, and brake fluid will probably all need to be replenished during your maintenance appointment after 100,000 miles.
Always remember to start by reading the service manual that was created by the people who planned and constructed your car. There will be suggested timing for your 100k mile servicing.
Bring your automobile to your neighborhood auto repair shop so a dependable and highly educated mechanic may perform a comprehensive examination.
And after 100,000 miles, make sure to keep up with routine auto maintenance; who knows, your automobile may last another 100,000 miles.

Why is my brake fluid dark in color?
The most frequent cause of brake fluid that appears brown or black is because normal aging has progressed too far (you haven’t changed the fluid in a while). As contaminants build up in the fluid, the color becomes darker and the effectiveness decreases.
What shade ought brake fluid to be?
Healthy brake fluid should resemble the color it had in the container before you first poured it into your car’s reservoir: virtually clear with a yellow tint.
How much does it cost to flush the brake fluid?
It typically relies on the replacement brake fluid you choose and the local labor rates for auto repairs. Additionally, it might be affected by your car’s year, model, engine, and manufacturer.
