Brake fluid flush process? '21 TRDOR, 4x4, AT.

DCSB 2021 TRD OR 4x4 AT

I've been searching high and low for the definitive guide to doing this. I've come up with quite the mixed bag of information, so I figured I'd ask the enthusiast.

Does anyone know how a brake flush is accomplished on the 3rd gen TRD OR.

I'm doing front rotors and pads soon and I've found during my research that it is not a bad time to also go ahead and flush the fluid, as compressing the pistons during pad removal will potentially push contamination (if any is present) back up towards the ABS system.

I do not have a scan tool, of which may be capable of initiating a bleed or flush process so I'm trying to figure out the answer beforehand, before I just immediately resorting to paying the dealership to do something that I may be capable of doing myself.

Thanks!

Picture of my truck because why not.

 

It’s not something I worry about. However if it concerns you, crack the bleed zerks before you compress the pistons.

 

I agree with the above, but I am just kinda surprised you already need new brake pads on a 2021. I would’ve thought they would have lasted longer than 2 years, but I don’t drive that much anymore with a home office.

IIRC there is a way to use the OR electric brake booster to pump out the fluid (read about in the 2nd Gen forum, but I had a Sport model at the time).

 

When ABS came out I added cracking the bleeder screws when compressing the pistons to my brake service routine. This nifty tool makes compressing the pistons easy.

 

Also interested in this. I’ve read from some posts that it may be possible on TRD models that you can rely on the electric brake booster as a built-in brake bleeder. I.e. crack the bleeder screw while the engine is on, then depress the brake pedal and the system will automatically pump fluid through the lines. Can anyone confirm if this is true, and if it’s possible to crack all 4 wheels at once and knock it out in one go??

 

I recently change front and rear pads. I did bleed it with engine on and NO you cannot bleed the 4 in one time just one at time and do the rear passenger first and so on... with a help of my son for pumping the brake pedal.

 

Do the flush BEFORE you change the pads if you are concerned about debris back flushing.

 

Flush is a flush; isn't going to matter if done before or after. I've always bleed/flushed the system last after pads/rotors were installed.

 

I doubt you have any debris in the system anyway. It's a 2021, fairly new truck.
