Bleeding Brakes

I tried to bleed my brake fluid on my 2018 Tacoma TRD Pro and I was unable to get any brake fluid out from the rear passenger brake drum nipple using a clear tube & bottle. Is there something I forgot to do

 

Turn truck on, (engine doesn't have to be running), and have someone pump the brakes like you'd traditionally do.

Lots of fluid comes out of the rear drums, way more than the fronts.

Thank you

 

It worked. I pressed the start button so that all the dash lights turned on but did not start the engine and I was able to bleed the brake fluid in the lines.

 

Your suggestion worked flawlessly. Thank you sir. Much appreciated

 

Happy to have helped. I have a big brake kit on my truck and I've bled the brakes numerous times to get the pedal feel up to my standards. If you didn't change lines or anything you're good just going around the truck once or twice to get the old fluid out.

If you change the lines I've found it's best to bleed the system completely twice, drive it for a week, then re-do the bleed process.

 

is this the same procedure for all trims? Read a few places that the process varies between sr5 and TRDOR/Pro models due to the design of the system. Going to need to change the fluid in my sr5 soon.

 

This is only for the Off-road and Pro trims with the electronic brake booster.

The other trims can have issues getting the air out of the ABS module without taking it to the dealer.

I've bled brakes at least 100x on a ton of cars, I hate it, but I make sure to go around the car at least twice everytime. Never had an issue in the last 20 years being able to get a firm pedal.

I've tried to use vacuum bleeders and power bleeders, never had any luck except for the good ol manual brake bleeds.

 

what did the FSM say

 

ATURK, I went around the truck once but I do like the idea of doing it twice. I will wait a week or two and do it again. Do I need to bleed the ABS module on my TRD Pro as well? Please advise

 

No, typically you do that only after replacing the master, booster or the ABS module itself. In all standard brake bleeds across many vehicles, I've never had to bleed ABS.

 

Nope, just go around the truck again and you'll be fine.

 

Why haven't you had luck with power bleeder? I've used mine on all of my cars/trucks including Tacoma with excellent results.

I ordered and received a power bleeder and reservoir adapter last year, for my 2018 OR. I plan to pressurized the master cylinder reservoir to 10psi and bleed my brakes.

I’ve read that the Off Road model bleeds the ABS itself while running, and using the traditional brake pedal bleeding procedure. Is power bleeding improper with this procedure?

 

Never had a pedal that was 100% firm after a powerbleed, I always would go back around manually and the pedal would firm up. Powerbleed is great for dumping old fluid and replacing with new though.
