TRD Gen 2 Brake fluid change

I have an 05 that is just about to hit 100k I don't know if the brake fluid has ever been changed... it's dirty... pedal is squishy... I just did the front rotors and pads (powerstop drilled and slotted)

Now I want to do a fluid change and have been seeing alot of conflicting information so just want to get it all straight....

My first question, is I've done dome research and stumbled on the necessity for a gauge/scanner to properly do the change on trd models (gen3)...
Is this also the case for Gen 2 TRDs? Do I need to plan on some extra steps?

Second question is what fluid should I run? I'm eyeing oem toyota dot 3, but is there really a benefit in that over some Prestone dot 3... performance and lifespan wise, would I be better off running 4 or 5.1 especially with it being an older system?

Is 32oz enough to flush?

1/4" ID hose?

It's been a while since I even looked at the bleeders but I assume there is rust on them, in the case I round one out what is the specific part or size for them? Might pick a couple up just to have on hand.


Thanks guys.

 

No special gauge/scanner required to change brake fluid on a 2nd gen. Have a look at the fill cap on the master cylinder reseviour - it will tell you the fluid type - brand isn't going to make any real difference, as long it isn't some brand from the dollar store. 32oz may be enough, but if the fluid is really dirty, won't hurt to have an extra bottle there just in case. No good getting partially the way through the job and running out of clean fluid. Brake fluid is hydsoscopic (absorbs water) so once you open a bottle, it wouldn't keep it for the next time, I'd get rid of it responsiblly. No sure on the hoze ID or nipples. I replace my fluid every 4 years. More time dependent than distance driven.

 

Adjust rear shoes first, gets more pressure to the rear and will firm pedal up.

standard bleed is all you need, scan tool bleed is only if air is induced.

Dot3 is what the truck calls for and does not benefit from anything more.

 

This.

I grab the prestone DOT 3 at the auto parts store and keep things fresh with that, zero issues. 3/16ths tube for the bleeders to go to a bottle for disposal. 1 Quart should be enough, just suck out at much of the old as you can with a syringe from the master cylinder before adding new.

IF you have the quite rare VSC option on your 05 with the electric boosted master cylinder (which is easily identified by the lack of the big ole vacuum chamber of a vacuum boosted master cylinder), you will get slightly easier bleeding to the rear of the truck. With the key to ON - engine doesnt need to be running - Have someone at the rear bleeder (passenger first, then driver rear), press the brake pedal and hold and once resistance is felt, have your partner in crime crack the bleeder while you hold the pedal steady till new fluid comes out and then they will close the bleeder and you will let off the brake pedal. The electric pump of this style of master cylinder will push brake fluid down to that wheel continuous as you hold the break pedal as is. WATCH OUT IT WILL GO QUICK.
