If you suck too much fluid from the master cylinder you run the risk of it running too dry and as a result you might have to bleed the master. Just bleed the calipers and add fluid as you bleed.
But the master is the reservoir. So this is where most of the contaminated fluid would be sitting right? So why not remove the most contaminated fluid first, before cycling it back thru the system? Im still learning myself so dont take offense
@@d3s1r3dpk You can definitely suck some fluid from the master but just take a little bit. I've seen situations where some take more than they should and they had no choice but to bleed the master cause the brakes weren't working properly. The hydraulic system is a closed system so if it's dirty at the reservoir than most likely it's dirty all throughout. You could take a sample at your first bleed and compare it to the fluid in the reservoir and make a comparison.
can you bleed out the system from one caliper if using a pressure canister attachment on the filling reservoir, apparently new fluid won't mix with old fluid. is this true or nonsense ?
damn all that air and putty fluid is nasty, just about anyone who's bought a newer car w/ poor maintenance has dealt with this. Hard to get the bubbles out without a device like this btw (either that or run a bleed procedure on your scan tool if applicable)
Just a warning though, do not let the brake fluid fill the reservoir up on the pump, if any fluid touches the rubber seals in the pump it'll dry out and crack the rubber, ruining the entire pump. So dump the fluid often. Also it can't flush abs pumps, because you have to electronically activate the abs pump to get the fluid out of it with a scantool. But flushing the lines is still a lot better than having all old fluid.
Man you cant se the real boiling degree in the fluid resavoir! You need to test some of the fluid in the pipes at the wheel... The fluid in the top of the resevoir is not pure brake fluid its filled with condense water from when the fluid gets hot and cools down.
Brake fluid is hygroscopic, you’re dumb to just introduce air into the system like that, never let it go completely down even when bleeding brakes. Now you will have to bleed the whole system for air particles and bad fluid. Good luck with that now!! 😂
Do you even know how this works??, it's just works on conductive , tells you the range of water containt, more water, more conductivity will be, you can use multimeter if you are that pro

What?
If you need any clarification let me know@@gtr485

Best content around and he gets straight to the point
Thanks 🙏
Does it matter if brake is disassembled? Replacing a wheel cylinder and dont want ANY old nasty fluid into the new cylinder. Thx.
How are you avoiding getting air into the system using this method???
It won't get in, bc you will only suction

Does your disintegrate after use? The brake fluid makes it real brittle
Thanks for sharing I appreciate that.
No problem!
Is there any chance if the breakfluid is very dengerous already and take it all from the system? And put new 😢😢😢 i got a big problem
Is that a Phoenix injector?
Excelente hermano buen procedimiento para cambiar el líquido de los frenos. Está herramienta tipo bolígrafo nunca la había visto.
Gracias 🙏🙏
Don’t rely on this tool, it will provide bad info. Get a better one, this one has to many bad reports and people changing brake fluid when not needed.
What's the name of the section device you're bleeding brakes with can you tell me the name so I can get one ?

Making it look so easy 😂 Fellow mechanic here 🧑🔧
thats the name of tool you used to pump out old fluid?

Use a Turkey Baster..... works fine!
This dude just pushed air into his system
😍😍😍😍
Could you send a link with this led indicator please? Or what is it calls?

@@AliMECH Thanks for the link.
I had severe doubts about this.
I checked it out: Not totally convinced but will give it a shot at that price. Thanks.
Harbor freight wins again
For what car is this

agree. I don't let brake fluid go below min level. I check/refill after bleeding each caliper.
You seriouslt used an led inducator to tell if thst fluid wad old 😂😂😂😂😂 just look at the color. You online mechanics are somthing special
