HI ! I brought my 2017 nx200t 33,000 km in for a oil change and was advised that I am over due for a brake fluid flush, and that it should be done every 2 years ? is this correct ?
I am not very good with cars and wasn't able to find it in the car manual
I live in Vancouver, Canada if that makes any difference.

 

3yrs / 30k miles should be 100 bux or so to flush brake fluid....I need to do mine, Im at 40k woops.

 

German cars recommend brake fluid flush every 2 year, I guess the Japanese are starting to do the same. Personally, I think its an over kill but you are simply buying insurance. Brake fluids attracts water and water can cause corrosion in the braking components.

 

If you environment friendly then ideally you want to inspect the brake fluid/system to check if moisture and contaminants has gotten inside and if the color of the fluid has darkened. if yes, then change. However since labor is so freaking expensive the inspection cost maybe same as replacing it. I got it changed at a toyota dealer for $110.

 

I just did mine on my 3 year old nx. It’s cheap. Cost me $6 for the 32oz Prestone dot 3 at advance auto. $6 for fluid that need to be changed every 3 year is a steal. Lol

 

You did it on your own? You bled brake actuator and ABS block? Care to elaborate, how you managed to accomplish this, as old school press pedal and release bleeder valve technique easily damages those components and bleeding is done ONLY with Techstream?

Besides, brake fluid is done every 30 000 MILES, what is 48 000 KILOMETERS, and OP clearly speaks of KM, not ML.

 

I bled it the old traditional way way with a second person in the car pumping the pedals. Always been doing this and even in the dealer until they bought a machine.

 

You can buy brake fluid testers yourself on Amazon for $30 and it takes less than a minute to dip it in the reservoir and have a little peak with a flashlight. The labour for inspection rather than blind replacement is silly easy. Brake fluid should easily last more than a couple years.

 

If you say so.
I have seen enough busted brake actuators at TN after bleedings done that way.
Attached snip is only first step of about 40 something steps procedure with Techstream.And I am, actually, very serious about this. Actuator is rtaher expensive piece to replace to fool with.

 

So as right as you are about bleeding, you're also slightly wrong. From an empty system, you 100% definitely need to do as instructed above. From a full system though, you can bleed the lines using traditional methods...with two caveats, 1) you will miss certain parts of the system, so there will still be old fluid, and 2) if you run the reservoir down too far you will introduce air that you can't fix. So for just a quick clean out and if you are careful about the fluid level, you can bleed the system without issue. This process (line bleeding, not full system bleeding) is documented in the NX shop manual, see below:

 

This brake flushing procedure seem complicated enough that it is not worth saving the $80 and try to DIY.
