Boosted master cyclinder?

I have a 2021 TRD Pro Taco how do I find out if it has electrically assisted boost master cynlinder? I cannot find it in owners manual.

 

I think the ATRAC/MTS/CC models have boosters?

 

I thought the ones w crawl were electronically boosted.

 

OR’s and Pro’s have electro/mechanical boosters, the rest have vacuum assist. Or am I wrong?

 

Pretty sure that's correct!

 

That would make sense that any truck with Crawl control has it. Thanks guys!

 

You would be surprised at how soft the vacuum models are compared to the electric. They are far better for brake feel.

 

My foot agrees. I still struggle with smooth stops, 3 years later

 

Another way to check is by popping the hood. The vacuum assist system has that drum behind the master.

 

You are correct in the A-TRAC and Crawl Control Off Road and Pro models have the electro-booster, however the 2 wheel drive Off Road should just have the regular style vacuum booster.

 

I’m constantly reminding people Toyota made a 2wd OR, how could I forget. Thanks
