   Recent findings conducted by the National Car Care Council revealed that 86 percent of the cars they randomly checked during state vehicle inspections, had at least one item that would cause the car to fail. Fifteen percent of these cars had low, contaminated or worn-out brake fluid. To put this another way, more than one in every 10 cars you are traveling with along city streets and highways has the potential of a brake failure due to brake fluid issues.Brake fluid is the key ingredient in any hydraulic braking system. The fluid is not only subjected to hundreds of pounds of pressure on many occasions during your drive, it is also a lubricant for the rubber components in your master cylinder, wheel cylinders, calipers and hoses. Additionally, brake fluid has corrosion inhibitors that keep the bores of hydraulic cylinders from rusting and pitting.Many of today’s brake fluids are made of polyalkylene glycol which is hygroscopic, meaning it absorbs moisture. This can be a good thing and a bad thing. The absorption of water promotes dispersal throughout the braking system and prevents “pooling” of the absorbed water in low-lying areas of the brake system where corrosive acids can form and make the components deteriorate at a faster rate. Water in a brake system will also freeze or boil faster than the fluid. Hygroscopic properties can be a bad thing, though, because the fluid will actually draw moisture through porous metal surfaces if the fluid has lost its corrosion-preventative abilities.Used fluid, when tested with chemical test strips, can sometimes contain up to 8-10% water contaminants after several years of use. Changing of the fluid whenever a brake component is being replaced is always recommended but seldom done, especially if you are fixing the car in your driveway or garage. Most service shops will recommend a flush and refill be done; however, cost-conscious consumers may opt against this for sake of saving some money on the total bill. A quick search through your owner’s manual will find a recommended service interval of roughly every three years that a flush and refill should be done.When replacing brake fluid, there are several different types to choose from. The easiest way to determine which fluid your car requires is by consulting your owner’s manual, or by locating the specification stamped on the master cylinder reservoir. Most American-made cars used DOT 3 brake fluid until the mid-1990s. DOT 3 brake fluid has a dry boiling point of 284 degrees, which is fine for brake systems with large brake drums and thick disc brake rotors, where brake heat can be easily dispersed. It has a viscosity of roughly 1500 at -40 F.DOT 4 was used by many British or European cars and is also a poly-glycol base. DOT 4 absorbs less moisture than the DOT 3 fluid, and many enthusiasts have converted their hydraulic brake systems from DOT 3 or DOT 4 for this reason. Changing the fluid is not all that is involved in this conversion, though. To prevent cross contamination you should also change all the rubber components in the brake system. All steel lines and brake hoses need to be flushed, too. DOT 4 has a boiling point of 311 degrees F., and it is rated at a viscosity of 1800 at -40 F.DOT 5 is silicone-based brake fluid and is used in most new cars today. DOT 5 is expensive, but it has a dry boiling point of 356 degrees. Newer brake rotors tend to be smaller and thinner, which means they disperse heat a lot less efficiently. Also, DOT 5 does not absorb any moisture. DOT 5 will not harm painted surfaces and acts as a weather barrier for your brake system, preventing rust. DOT 5 can be used as an upgrade or replacement for both DOT 3 and 4, but should not be mixed with any of the other fluids. The procedures to convert your DOT 3 or 4 systems to the silicone-based DOT 5 are similar to the Dot 4 conversion procedure mentioned above. Silicone-based brake systems tend to be more difficult to bleed, but once this is accomplished, a DOT 5-filled system will resist rust better and last longer than the other formulations. Silicone brake fluid is also much lighter in cold temperatures, only about 900 weight at -40 F.A new formulation has recently been developed called DOT 5.1. This fluid is identical to DOT 5 silicone in both boiling point and viscosity; however, it is compatible in the poly-glycol based systems and anti-lock brakes as well. DOT 5.1 can be used in place of either of the poly-glycol-based fluids even though it has half the viscosity of DOT 3 or DOT 4 fluid. In fact, DOT 5.1 can be intermixed with the other non-silicone based fluids.Many imports also require special brake fluids be used, so as not to void original equipment vehicle warranties. Pre-2005 Audis and VWs use a Super Dot 4 that is light yellow in color and has a boiling point of 509 degrees F. This fluid was also OE-specified fluid for BMW until mid-2002, and all new Land Rover, Jaguar, Volvo, Porsche and Mercedes. Audi and VWs after 2005 use a low viscosity type DOT 4 LV that is yellow in color and has the same boiling point as Super DOT 4. The LV formulation is also used exclusively on Mini, Saab and BMWs built after mid-2002. Both of these import-specific fluids are available from the manufacturer Pentosin (as well as others) and sold at many dealerships and retailers, but they are not necessarily out front on the shelf with the other more common DOT fluids.Amazon why do you ship food with brake fluid?

   UPDATE BELOW, at the end:Ever since COVID I’ve been writing more reviews than I used to so hopefully you’ll find this fair and informative while making your decision. I gave this 4 stars so this is fair but you should really read this before buying, depending on the type of car you have.I own a 2010 Mercedes-Benz C300 Sport and it calls for “Dot 4 Plus” which all of us MB owners know that’s just marketing. So I generally use Pentosin SUPER Dot 4 (which is equivalent to Dot 4 Plus).I recently did new rotors and pads and a brake flush so I figured I’d try this. Please note that I know how to do a flush and I didn’t have new air enter the system, but this brake fluid is really just OK and not all that inspiring. I was hoping to get an even firmer pedal but I didn’t. The pedal’s firm, but based on this fluid, I was hoping for better.To be honest, last time I did a brake flush (a few years ago) with Pentosin SUPER Dot 4, there was clearly a difference with bite and pedal firmness. And I didn’t change brakes at that time. And now I have new pads and rotors and this just seems ok and “normal.” Buzz kill…Maybe the point of this fluid is the longevity versus other fluids. And something tells me this might be a hybrid fluid, yes? Of course Dot 4 can be used for Dot 3 systems and Dot 5.1 for Dot 4 systems – but this fluid only says compatible with Dot 3, 4, and 5.1. It doesn’t seem to tell you what it is, though. WHAT IT IS ACTUALLY? Is it Dot 5.1 or some type of bastardized hybrid? I love German products but German products also have quality distinctions. I think this might be “good” quality German brake fluid, mid-tier. Not high quality. Maybe if you have an American or Japanese car that takes Dot 3 or even standard Dot 4, you’ll feel a nice difference.But for those of us who need a higher quality fluid from the start, I had high hopes for this German fluid, but it just doesn’t seem to be the same as Pentosin or Mercedes factory fluid (which I don’t buy since it’s over-priced compared to Pentosin).I’m thinking about changing back to Pentosin SUPER Dot 4 for a better braking experience. Kind of a bummer to put brand new cross-drilled rotors (which is factory for the Sports models) new quality pads, and just have “OK” braking. I want that nice bite back that I got with Pentosin. And Pentosin is just $2 more on Amazon or that other large auto parts retailer we all know about.Lastly, and I don’t know if this makes a difference, but the color of this fluid is more yellow than Pentosin. Pentosin (and even PRESTONE Dot 4 which I use for my father’s car) are almost clear with a slight yellow. This has a darker, more full yellow color. Again, don’t know if that means anything but wanted to point it out.UPDATE: I’m not changing how many stars and keeping it at 4. Even though I didn’t want to buy more new brake fluid and waste money, I did wind up flushing out the Bosch and put in Pentosin SUPER Dot 4. As I suspected, the Pentosin immediately gave me a better pedal and stronger bite, and with the new pads and rotors, now I feel this is a complete brake job. For American and Japanese car owners – this may be great. For those who drive German cars (including VW), I’d say PASS on this since you’ll probably be disappointed, in terms of performance. Maybe it lasts a little longer (one year longer) but you lose out on performance and again, we don’t even know what type of fluid this is – it’s just “compatible” with 3, 4, and 5.1. I’ve never seen brake fluid that doesn’t even tell you what kind of fluid it is. So much for trying to buy a cheaper, German alternative. Lesson learned.

   The original product I received in 05/2022 is in a metal can and with the same painted on label. No paper label here.What happened to the claim that ” Due to the product being made in GERMANY, DOT (department of transportation) regulations and American labeling laws require exported fluids such as this to have a paper label affixed stating all specs and the like. This was CONFIRMED by a discussion with a BOSCH engineer on 4/29/21″? Did the “American label laws” changed in May from April?The product I received is great.

   This appears to be a very high quality fluid. Will update after it has been in use for a while.

   Bosch ESI6 isn’t technically DOT 5.1. It exceeds DOT 5.1 specs while remaining compatible with DOT 3/4/5.1.Note DOT 5 is different from DOT 5.1, you can tell by the numbers.Used this to flush seven year old brake fluid in a Fiat 500e, and the difference was immediate. The brakes were really grabby at low speed, and now they’re extremely smooth. The difference is huge, and it’s much nicer to drive around town now. As the car is an EV, we’ll never need the high performance aspect of this fluid, but the lubricity and high-specs are nice to have, especially for the reasonable price.

   Brake fluid and water don’t mix, so finding a 5.1 fluid in a metal can is a perfect combination. Yes, plastic containers don’t let the brake fluid seep out, but they do let moisture in. Keep your brake fluid dry with the longer shelf life from these containers.As a brake/clutch fluid, it works really well. Seems to have a higher boiling point and works better in summer as a clutch fluid (for all you 350Z, G35 and WRX owners).
