Brake Fluid Flush A Must!

[CrawlSlow]

Flushed my brake system, glad I did it! The fluid that came out was super dirty!

How many miles? I did my 2018 with 50k and I saw the same. Very dirty fluid out. Was surprised. Plan to change again at 60k just to see.

I bought the truck used over 200k. It seems like it was never changed. Maybe it was the fluid that came with the truck 

 

It took atleast 1 qt of new brake fluid to flush out the dirty fluid on the rear passenger side. I activate the abs module every 30 pumps just to make sure there's no dirty fluid left in the abs module. This is probably another reason why so much dirty fluid came out. The rear driver side and front passenger side took 1 qt and front driver side took half qt.

Brake fluid is over looked all the time and it is one of the most important fluids in a vehicle.  The only other fluid that was over looked was power steering.

I flushed mine out at I believe 36-38k and plan to do so again next year. I always burp the bleeders now every year just to keep them freed up so it doesn't snap off on the caliper like I have had in the past. I honestly swear my brakes are way better for stopping power after I flushed them out 2 years ago. They never were a problem but after doing that and changing the pads to napa's high end pads I have way better braking power than I ever had.

 

I'm not sure if you just cracked the bleeders and let them gravity feed but when I flushed mine, I used my mityvac pump and bleeder rubber fittings to fit on the bleeder and started with the rear passenger caliper then went to the drivers rear, passenger front and drivers front in that order. I kept an eye on the reservoir to make sure it never went empty and used prestone brake fluid.

 

I did go on a gravel road after bleeding them to force the ABS to kick in but that was only twice that I did that, it didn't seem to help any aside from the bleeding/flushing but I wanted to do that just to be safe.

Flush again, I'm sure there's more junk after you engage the abs.
