Geniune or OEM-equivalant Parts and Equipment. Dealerships have access to the latest equipment and source parts directly from the manufacturer wherever possible. This means your BMW gets a higher-quality brake fluid change that leaves it purring for years to come. Bear in mind that when it comes to servicing your brake fluid, it is best to get it done by a professional.

Without servicing the brake fluid at the appropriate intervals, you run the risk of the brakes becoming less responsive and less effective — something that you don’t want to encounter unexpectedly while you’re driving. You are more than capable of purchasing almost any brake fluid from any branded manufacturer that makes it. However, we found out that just because you can use any brand does not mean you can use any break fluid because there are different types.All DOT 5 fluid is thin (low) viscosity at no more than 900mm2/s (-40°C) with boiling points of 260°C/ 180°C.

If you have any questions about what type of brake fluid to use in your BMW, be sure to consult your owner’s manual or ask a qualified technician. Using the wrong type of fluid could potentially damage your brakes and void your warranty. A Brake Fluid FlushIf you don’t change your BMW’s brake fluid it will lose effectiveness as it absorbs moisture, leading to a risk of brake failure and corrosion of the brake lines. You can expect to pay anywhere between 100 and 200 dollars to have your BMW brake fluid changed, with the price likely to fluctuate depending on the model of your car as well as your location. Modern engines place extreme pressure on the oils and lubricants that keep them running and protect them. You need to have lubricants that respond to the task. Castrol manufactures a range of BMW engine oils and BMW brake fluids for all models of BMW cars. You’ll know if your BMW needs brake fluid because your car will display a warning light on the dashboard if the fluid isn’t changed at the recommended interval. Therefore, because brake fluid is hygroscopic, it will tend to absorb water and moisture. If there is excess water in the brake fluid, it will lower the boiling point and reduce braking performance.

The brakes are one of the most important safety features of your car, so it’s important to act immediately when you see this warning light. It’s important to be careful when topping up brake fluid as the formula is hygroscopic, meaning it absorbs moisture from the air, which can make the fluid less effective. If air enters your brake fluid, your brakes may feel spongy, and your vehicle will take longer to come to a stop. If this is the case, you may need to bleed your brakes.While DOT 5 is your silicone-based liquid, DOT 5.1 is reserved for your low viscosity glycol-based brake fluids. This means that if a normal viscosity liquid has a boiling point that reaches that of a DOT 5 level, it will be classified as a DOT4/5 or, in other instances, a “super DOT 4”.

You may not notice them when they’re working, but you will when they’re gone! Brake fluid should be changed every two years, and while not a simple job, it can be done at home with the right products and tools - all of which you can get at Halfords. Remember that you should only carry out this procedure after having had your brake fluid serviced. Final Thoughts — BMW Brake Fluid Unless you drive something really, really old, your car is going to have hydraulic brakes. And that’s good, because hydraulic braking systems are commonplace and also the most effective. However, they’re only any good if they’re maintained properly. This is a general guide on how to do your own BMW brake fluid service. Always consult your service manual for specific instructions on bleeding the brakes on your particular model. BMW Brake Fluid Service Is ImportantRemove the old brake fluid from the reservoir using a clean catch container and save some old fluid to use as a reference when adding new fluid later You’ll see low and maximum markers – if the fluid is below the low marker, you need to top it up as soon as possible and arrange for your brakes to be inspected. it seems that the US DOT skipped an official DOT 6 grade. But some manufacturers are adopting the spec on their own and claiming “Dot 6”. But without a true published standard it's impossible to know what it really is. The DOT has published a “Class 6” and “Class 7” spec which is the same boiling points as previous standards but with even thinner viscosities. In general, BMWs require synthetic DOT 4 brake fluid for both the front and rear brakes. This is a high-performance fluid that can withstand the extreme temperatures and pressures that are generated by the brakes during hard use. DOT 4 fluid also has a very low compressibility rate, which means it won’t “fade” as easily as other types of brake fluid when the brakes are used repeatedly.
