Moisture In Brake Fluid

This short video explains more about what happens when you get moisture within your brake fluid and why it is important to maintain your brake fluid.

Did they run out of budget for the last 20 seconds of the film?

One of the biggest myth in the car industry. Beside the 7°C rule for mounting winter tires. 🤣

Okay ,so brake fluid can be absorbed through the rubber brake lines, atmospheric pressure, the brakes when applied have 10 times atmospheric pressure on the lines why doesnt the fluid leak from the lines?

Size of the molecules. Water is a nice compact molecule, brake fluid can by hydraulic oils or glycol ethers which are chain molecules.

Sir can I know the name of software used to create this impressive video

I changed brake fluid for the 1st time in a 17 year old toyota, myself using Dot3 toyota brake fluid, today the brake caliper engaing noise is gone, the brake work 50% faster .These problem were told to the local toyota dealership owned by toyota japan every year but they never found any problem.Some say brake fluid doesnt need to be changed ,it does.

I understand this video totally. IS there any actual evidence of scientific testing "before and after" a fluid swap to show this is actually a thing? I have a 15yr old car I have owned from new and I have never ever had the fluid changed. You would say it shoudl be done every 2 years. I would say not. Where is the evidence that it even needs doing, ever?

Does anybody know what the greatest contributor to water absorption in a brake system is? I know that the rubber hoses and seals can wear out, but if you had to rank it, which part in the system tends to cause the most water absorption? Is the master cylinder going to absorb more water because it has a greater amount of brake fluid in one place and so the hygroscopic effect is stronger? I am thinking it may be like a full VS half-full gas tank (since ethanol is also hygroscopic) where a half-full tank is more likely to gets bloated if there is an increase in temperature. This is because when you heat something up, the molecules move around and collide faster and there is more space to move around in a half-empty container than a full one. I realize it takes a tiny amount of water (like 5% by volume) for brake fluid to be considered "wet" so if you have a 500 mL master cylinder, that's only like 25 mL of water. I know the "water absorption rate" is affected by humidity (and that is dependant on dew point), but is there a way to quantify how much water brake fluid absorbs over time? In other words, a measure of how hygroscopic it is? Perhaps this is basically wet boiling temp? I know the difference between racing-oriented brake fluids like Castrol SRF and Motul 600 list wet boiling temp, but it doesn't seem to be provided for OEM brake fluid unless it is a sporty model.

Hoses [which are permeable] seals, and master cylinder assembly fill point. Older cars [like 4x drum setups] may have used a rubberized gasket that would follow fluid levels like an accordion bellows. If the cover was flat and tight, life was good - as long as that gasket was not pinholed or cracked they kept out atmospheric moisture well. Modern cars use a master cylinder cap that well... isn't usually all that inspectable and is prone to breathing as it ages despite more modern materials. A tight system? Good 3-5 years, depending on where the car lives. My truck [a 1996] has no apparent leaks, but system isn't as tight as it once was. I used to changeout/bleed system every 5 years, now I find it needs doing every two. If I had a tester, I would plan maintenance if a test showed 3% moisture, but I don't so I take note of color shift over time. The funny thing about anything hygroscopic is the substance can only bind up so much water molecules as a % of system volume. That is saturation point - any new moisture, and you can have pure water in some areas of the system - lowest points are always hit the hardest as water starts displacing brake fluid. I asked anyone I knew years back what exactly is that point: 4.2%? 5%? What? Nobody knows the answer because... its not promulgated by the fluid manufacturers. I stumbled on this vid trying [again] to discover real information about dot3/4 fluids.

Below 300 MV, need to flushed ???? Thanks

[@Elvis-dw7ux]

Zabardast cheers from Toronto.....at 25,000 kms 4 years old Mitsubishi RVR losing DOT4 fluid.....but cannot find the leak! Please advise. Also, the stupid Reservoir is inclined for some reason?

[@judysoetedja]

Worn out brake pads? But it's only 25K & 4 y.o.......

What's a shedule?😂

[@GCS88]

Let me guess... You're American or someone who learned USA English, as You can see from the channel name it has 'UK', Shedule is the way schedule is pronounced in UK English which IS the original English, it might come as a surprise to You but the English language being a internationally known language has formed different kinds or variations over the years including the one You know.
