Brake fluid change ?

[The Critic]

I do not have access to details to back anything up, but my 2 cents worth of guess about that is that the dealership where the service manual would have it done at has the ability to use the OBD2 port to command the ABS to cooperate with doing a forward flush. And that is something my Blue Driver OBD2 port device will not allow me to control.

It depends on the manufacturer service procedure for brake fluid replacement. Some manufacturers require for the ABS to be activated, but that is rare. Most only ask for a normal brake bleed to be performed.

When you are retired, and have time, it can be nice to do it yourself. That way you know it was done trying to do the best posable job. And you might even save a few bucks when it is all done.

I have all of the the tools, and methods to easily bleed brakes all by myself, including a OTC air powered vacuum bleeder, and a Motive pressure bleeder. But with 9 vehicles, with 6 being seldom driven, I just take the lazy way out, and at least suck out the reservoir and add new fluid whenever possible.

I believe there is a tech with a Youtube channel that does that...I've done it myself as well.

BTW, I got a nice decent wood chair that does not have side arms, and was thrown out. Fixed the broken part on the back of it with a little glue, and a couple of screws, and cut the legs down so as to have the seat 10 inches above the ground. And with one of my 3 inch thick boat cushion, that will be at 13 inches above the ground, and make a nice free brake work chair.

The reverse flush of the Pheonix systems takes advantage of brake systems in general being designed to allow free reverse flow. I will call Pheonix up and ask them if there reverse flush system replaces all the brake fluid in all areas including all of the areas of the ABS and the front to back proportion control valve if my vehicle has that.

Not trying to get into any argument here. You brought up a valid point, and I will confirm that the Pheonix reverse flush is an appropriate tool to use on my Honda CR-V before I purchase it. Thanks for the heads up.

My worry with the Phoenix method(and it’s a sound method based on simple physics that air rises to the highest point, as a matter of fact SRAM’s Avid mountain bike and HRD road/gravel bike brakes are bled from the calipers) is pushing contaminated brake fluid from the wheel cylinders/calipers into the ABS/ESP modulator. Replacing that can be an expensive affair.

One of the recommended maintenance items on my 2018 Titan is " Brake Fluid Change " . The truck is near the 40k mile mark . It's still under warranty so should I go ahead and get it done to comply with the maintenance schedule ?

This was my original post . I don't know how this became about " Phoenix methods " and OBD devices and types of bleeders , etc. I'm just going to have it done at my next oil change . Party on ....

This is exactly correct, and my information comes from Phoenix themselves. I originally learned from Trav that ABS systems have non-serviceable built in filters and should NOT be reverse flushed. This is backed up by Phoenix systems: https://www.brakebleeder.com/preventing-damage-abs-modulators-brake-pad-replacement/
Trav's advice on this which aligns with Phoenix systems is to perform a top down flush first, then do a reverse flush if necessary to remove all air. I emailed Phoenix systems regarding this and here is their response: https://bobistheoilguy.com/forums/threads/turkey-baster-method.183304/page-3#post-5864879
Additionally, I'm using Bosch Esi6 brake fluid, which is replacement for DOT 3, DOT 4, and DOT 5.1, and has an expected service life of 3 years: https://www.boschautoparts.com/docu...I6+Flyer/a112e37e-ce73-8cc7-3f9b-fbf126a44ebe

75% of the time it can be done without removing the tires. Just need some offset brake bleeder wrenches.

With a lift its a joke, so easy. I have a dirt driveway. My neighbor was killed from a jack stand slipping out on him... Since then I always use 4 jack stands if I ever crawl under. Even that gives me bad vibes.

I will own a lift soon, they go for $1500 around here used. I just have to build a new garage first. (honestly it will probably never happen).

Pave a couple patches just large enough to be the foundation for jack stands, probably wouldn't take more than ~$75 worth of concrete and rebar at the hardware store, if even that. Even a 2x2' square beats dirt.

I think we’ve answered the OP question, and wandered too far off into other topics. Thanks.
