2017~2025: 2020 Mazda CX-5 Brake Fluid Change Questions

[brownbearuva]

Greetings all. I was all set to (DIY) change my brake fluid out when I did my last oil change. I was planning on following ChrisFix’s method of using a Gatorade bottle and a tube. However, I ran into two issues that I was hoping to gain some insight on:

1. Pretty simple, but I didn’t have the proper wrench size for the brake line nipples on my wheels. Does anyone happen to know what size wrench I’ll need/is it worth getting a flare nut style wrench?

2. I couldn’t fit a turkey baster in the main reservoir to suck out the old fluid, due to the long-necked shape of the reservoir. Can anyone recommend a way to suck out as much of the old fluid as possible?

Thanks in advance— I couldn’t find any information about these items from a cursory search. Also open to any general advice or tips y’all may have for doing the brake flush.

OK I both my Mazda last year.. My best advice, go old school. Don't buy those $20 kits, pump. The fitting won't work. I went through 2 of it.

Get a small Gatorade bottle, 1/4 in. I.D. x 3/8 in. O.D. x 20 ft. Clear Vinyl Tubing. Cost me $7 buck at home depot. And one of those cords to hang bottle high

1) I think I just use small adjustable wrench. It's very small in size, so it's hard. Don't over tighten it.

2) Even a blaster won't go all the way in. You can some lint free towel and drain it. Or better yet, just flush it all the way out. Break fluid is cheap...$5 for latest size... You want each line to bleed clean. Check my photo out. What you want is to cycle new through each line...I got so much leftover from a large bottle still. I'm keeping it in case need for something, but you can't keep open brake fluid too long. It WILL absorb moisturizer. I have special bin.

3) check out at least 3 YouTube video. Remember to bleed in order...

4) bonus tip I went through 7 major brands so brake pads. So far oem Mazda last the longest for me. Rotor wise, oem has the anti rust with salt thing. So if you swapping to 3rd party.. It can be cheaper. But if you upgrade to "high end with salt protection"... Oem Mazda is better.
