3rd gen braking randomly

driving down the highway and the trucks rear drum brakes lock up and the front brakes decrease me to like 30mph on the highway, no brake indication came in on the driver info panel, nothing. ive also had the brake screen come on while driving with no car or anything else in front of me, anybody have experience with this or is it just me?

 

Toyota Safety Sense maybe?

 

That's not normal or ok. Sounds like a dealership visit. Looks like you already have the factory Pro grille so they won't try and screw you out of your PCS and radar cruise.

 

I think you already know what to do;, maybe you're just looking to vent, or one of the old coots on the anti tech crusade.

 

Wont the tech have to duplicate the issue in order to fix it? Maybe the OP is looking for more ammo to take to the fight.

 

sounds like that and a trip to the dealer. there's that tsb/recall on the grill sensor issue

 

Has your truck been lifted?

If so, there was a recent thread that had some similarities. It was the rear E-brake/brake-lines.

it has the stock 2.5" lift that comes with the pro

 

The drums LOCK, but your speed only decreases to 30mph?
I'll go out on a limb and say this isn't happening to anyone else..

 

The Pros come stock with a 2.5" lift?

 

Only the one's that have locking rear drums, and front brakes that slow you to 30 mph.

 

Pics of truck with so called factory 2.5" lift?

 

What if I told you it was actually a 2 inch lift, and it’s a 2.5 inch reservoirs on the rear shocks?

 

Fox "2.5" refers to the bore diameter...has absolutely nothing to do with lift or reservoir size.

And Pros are 1" higher than an OR from the factory...

 

Yep it’s the diameter of the shock body.

It is a 2 inch lift overall on the pros. The TRD ORs have a a factory 1 inch, factory, the pros have a 2.”

 

ORs have no lift over any other Tacoma, pro has 1” (on paper) up front only. Look at the Toyota specs, it’s very clear. Rear springs are identical on all models, and since there are no blocks, their can’t be a lift in the rear.

 

This is news to me, have never heard of this. Dudes on TW have literally taken measuring tapes to Tacomas at the dealership and haven't found anything of which you speak

 

To people saying "they locked but only slowed to 30mph" they locked up temporarily, rear wheels sliding and then let go around 30mph.to the people saying "what 2.5" lift" I'm new to the tacomas and the dealer claims a stock 2.5 inch lift, regardless to if it's a 2 5 or 2, its lifted more than stock
