[@NickWhite-rc5wy]

There is literally no evidence of crashes caused by old brake fluid. Leaking lines and cylinders losing fluid or letting air in can cause break failure, but even those are so incredibly rare they are statistically insignificant. Brake failures cause so few accidents that it is perfectly legal and extremely common for the person working on your breaks at your local Midas or jiffy lube to be a 17 year old drop out with about 4 hours of in the job training doing your breaks while the real mechanic does more complicated things, like swapping out MAF sensors and doing tune ups😂

[@davidneill9877]

That was very well-articulated. Another point to mention is with anti-lock brake valving being anodized aluminum that it can corrode with exposure to moisture and create anti-lock issues and also very expensive components to replace.

[@Rabbinicphilosophyforthewin]

@@1Cobranutthe only reason I didn’t kill myself and my family when I first drove down a long steep having never had an adequate downshifting lesson (grew up in the Midwest with no hills in sight) was because as a kid I’d heard my dad singing “Wolf Creek Pass” where the brake felt “like stepping on a plum.” Down the hill, I shifted my 5-speed Corolla up to 3 or 4 because it was revving hard and I felt like I had to shift up-which meant I was braking hard and often. Eventually I thought “This brake pedal is squishy and we’ve got miles to go down this incline. I’m doing something wrong and I’ve gotta stop right the heck now.” It was hard to stop but we pulled over and let the brakes cool. I didn’t say anything to anyone, just contemplated my life choices for a few minutes. When I got back on I resisted the urge to shift up when the revs went up and kept it in 2 the rest of the way. That’s how I learned, but it was a life threatening situation that scared me straight.

Good advice for the non-DIYer. I do my own brakes so if the color is getting like maple syrup or more than 3-5 years old I like to flush out. It's also a good idea to crack open the bleed screw every couple years just to make sure it doesn't get seized up.

I wouldn't wait even three years, never mind five, between flushes.

[@gariningleton3785]

​@@pulaski1right it's like $7 for a quart size of brake fluid and like $4 a pint and if know how to bleed them it doesn't take a gallon like the engine does and prolong the life of the braking system.

[@pulaski1]

@gariningleton3785 I'm not sure that flushes extend the life of the brake system, but they ensure that when I put my foot on the brakes, my car is _actually_ going to stop, so flushes probably extend _my_ life! 😀

[@killer2600]

If you're cracking open the bleeder then you might as well change the fluid. The recommended interval is every 2 years. Water in brake fluid enables rust and corrosion from the inside out. Changing the fluid will save you from costly repairs that you won't see coming.

[@thee_number_six6227]

​@@gariningleton3785where are you paying that, a quart here is $12-15. But yeah I'm in agreement I do my brake fluid every 2-4 oil changes. And I do those every 3-6 months depending on mileage. So that's a brake flush every 12-24 months. It probably helps that the hydraulic clutch in my truck is always a pain in my ass, so I always have brake fluid on hand.

[@snolbie1016]

If you want to change your own brake fluid here's how to do it: 1. First if possible put the car on 4 jack stands so it is free in the air. Remove all 4 wheels for easy acess and less of a headache and start from the side that is most far away from the fluid reservoir. (In most cases rear right)(from the perspective of the rear of the car) 2. Have a nice buddy sit in the car that will help you later. 3. Grab an old bottle and drill a hole in the cap with a see through hose thrue the hole you can now start. 4. Get the small rubber protection cap from the brake fluid nipple with (optionally a flathead screwdriver) and then first put the ring key on the nipple and second put the other end of the see through line on the nipple. 5. Now tell your friend to press the brake pedal nice and firm and keep holding pressure on the pedal. Now you can slowly turn the nipple open till the pressure is released in the bottle. Your friend has to make sure that he/she holds the pedal down to the floor untill you closed the nipple. Now he/she can pump the pedal a few times to build pressure again en repeat the process untill cleaner/yellow brake fluid comes through the line instead of old black/dark yellow brake fluid. The sequince would be left right - left left - front right - front left (on most cars) Tips: * Dont turn the nipple too tight!! These things Break easily and barely come loose after they are tightened too firm. * If you think a nipple is going to break or is taking way more effort to get loose compared to the others, get a mechanic to do it or use a torch and cool the nipple after heating with a watery cloth. Repeat till it comes loose(patience is key) you dont wanna break it. * Make sure the fluid reservoir doesnt dry out completely to prevent air in the system! Every few pumps check the fluid reservoir level and top it off with the fresh fluid. * I worked mostly at dealers and also universal garages and by my experience flushing your brake fluid is usually needed around 4/5 years. Most dealers will tell you 2 years but that's mostly for extreme situations. * Between 0.5-1.0 liter of brake fluid is usually needed for a complete flush.

My vehicle was over 10 years old /95k miles and had the brake fluid flushed and replaced. What a major improvement in the sensitivity in braking.

[@NathanAdamsCars]

I got a brake flush once. The tech left his wrench on the bleeder valve nut. As I drove home all was good, but while in a parking lot and making a sharp turn, I suddenly lost all break pressure. Then after straightening the wheels, brake pressure returned. Imagine the confusion I had and the trouble convincing the dealer that something was wrong. I went to another dealer and they found the wrench. It would impact a strut when wheels turned far enough and that would impart force against the caliper’s bleeder valve temporarily. Such a strange situation. Anyway, it was resolved, but not after much stress.

[@wmluna381]

[@mitsurage11]

Also brake fluid works as a lubricant for the seals in your master cylinder, abs unit, calipers, and wheel cylinders. Regularly flushing the system can help those components to last longer.

[@HaveUSeenMyBaseball86]

Are you sure about that? I would think if it's used for lubricant, then you would run out of brake fluid eventually. Only reason your brake fluid may look low is because you probably need new brake pads. Calipers are on slides and you grease those. Never see brake fluid lub them up.

​@trailmixbilly5985 if you're loosing fluid to a pad you need a new caliper piston seal. Which is in fact lubricated by the brake fluid as it's what pushes the piston. 99% of the time if you're loosing fluid it's because you have a leak.

The owners manual is gold! I had a service advisor once try to convince me I needed a new water pump just by looking at my car. I asked him what the basis was for his suggestion - he said that’s what the manufacturer recommends. I said that is unfortunate because the owners manual provided by the manufacturer recommends replacement at 90k miles, not the 50k that was currently in my car. He looked shocked that I even knew that. I reminded him that just because I have blonde hair and boobs I am very capable of reading an owners manual.

This is why every time i do break work on my car, i suck out all the fluid in the bottle and replace with new stuff. It’s the best time to do it, since you need to push in the clippers and push a bunch of the fluid from the lines into the bottle. The stuff in the lines are generally safe from water exposure, so doing this fluid swap is much faster and cheaper than a full system flush.

Something to mention is when replacing your brake fluid, you should purge/flush out the small amount stored in the ABS unit and its’ accumulator. This requires a computer to actuate or if unable, flush it the best you can normally, then find a gravel road and use the ABS a bunch of times. Then redo the flush.

This is how we change the fluid to avoid getting air in the brake system.

Good idea. I got one of those off Amazon about 6 months ago and found out my 26 year old brake fluid needed changed. So, I pulled all the wheels, removed the calipers, cleaned them all up and painted them, bought and installed some Russel speed bleeder screws, and flushed the system. Fortunately there wasn't any rust problem because it was a SoCal car that was only recently transplanted to FL. I'll be keeping a much better eye on moisture content from now on.

Don’t need any fancy tools; use your eyes. Since brake fluid is hydroscopic, when it absorbs water it will oxidize, turning a dark color. The darker it is, the sooner you need to flush it out. Or flush it out at regular intervals, such as 30,000 miles.

[@petrosspetrosgali]

That’s basically what I was going to say. I once took my brand new Nissan frontier in for its FIRST oil change at the stealership. The kid told me I needed to get my brake system flushed. I had him and the service manager use the tester in my brake fluid. It felt nice to see them both look so ashamed of themselves. I got a free set of weather tech mats from that oil change.

That tool is cool. I have always flushed new fluid in every 4 years, but also every time I replace pads and brake discs. To me, it doesn't make sense to push the old fluid back up into the system when you're compressing the caliper piston, instead just release the old stuff from the bleeder and then fill with new fluid and bleed as normal. It's a very quick DIY way to do a complete flush without any special tools.

[@williamalexander1743]

If you are pressed for time and you want to keep an upper hand on the condition of your fluid you can use a turkey baster to remove the brake fluid that has moisture in it and then top it off with new fluid. That will definitely help, but not actually cure anything.

I’ve gone 8 years on the same brake fluid with several cars in humid climates with no issues and the brakes worked like factory new when I sold them. I don’t know what people do to their brakes but ambient moisture seepage is not it. I’d wager more of the issues are extreme heat fatigue (track days, riding bumpers, burnouts) or environmental (deep water, snow/salt, etc). Old cars used inferior materials that would corrode regardless, but newer ones don’t. No reason to change it if it still works well. But sell more nonsense for a quick buck.

​@@nunyabusiness896 Very few cars use stainless steel brake lines, I highly doubt you've ever had the kind of money it takes to buy one.

Your head can't get wrapped around the concept that people who repair cars are the one's who see what goes bad and what causes it to go bad? No, they wouldn't know, you would, just because you had a car and sold it. How do you know how long afterwards it was until it blew a brake line? Ok, if she doesn't know what she's talking about then tell everyone, what causes rust inside of a brake system? Ever taken a brake caliper or wheel cylinder off that was bad because the bore in them got rusty and tore the seal up? If she's wrong then explain how it got rusty in there. "I had a car for 8 years and when I sold it the brakes worked as good as factory new". We know, us mechanics fix them all the time not long after the next owner buys them.

Brake fluid is Hygroscopic. It absorbs moisture from the air. Water is heavier than brake fluid so as you use the brakes, it works its way down to the lowest points in the system..... Calipers and wheel cylinders. And that is how you get a seized caliper and dragging brakes or locked up wheel.

[@mattdean7109]

I was hoping someone would bring this up. The old fluid in the caliper is the problem, not the reservoir. Water logged brake fluid at the caliper can also lead to soft/spongey brakes and brake fade as they heat up and the water in the line boils/steams off.
