When I had my tires rotated recently, I got the truck back and the spongy brake feel that all 4Runners I test drove had been replcaced with a more normal brake feel that engages softly at 1/4, normally at 1/2, and then you have your panic and holy crap after that.

Before it seemed like it had a lot more travel to it.

I told the dealer about it and he said I was nuts. I'm not debating whether I'm crazy, but is this some kind of learning/adaptive feature?

Also, is 15.8 mpg bad for a TE? The service tech said he crapped himself when he saw my display.

Never heard that the brakes could change... Perhaps you were low on air and it changed the feel when you braked. I have no idea.

15.3 could be good or bad. Hard to say. Depends on how much weight you have, tires, kind of driving you do, how you drive...
 
I do drive it like I stole it and it's in 4Hi about 25% of the time on fat BFG 285 TA/KOs which are D-rated.

Still, I was told that I should be getting 17-18. Which I just don't believe is possible.
 
I'm at about 6500 on my trail, and track all my mileage for work reimbursement...

I'm avg ~ 21-22 in town.
20 combined (this included up/down I70 west of Denver)
18-26 highway/interstate (depending on wind through WY, MT, SD, ND)

*Edit* oh yeah stock tires

I'm on BFG 285 KM2s, lifted with armor and think that would require some pretty gentle acceleration and nothing over 65 to average 17/18. Possible? maybe, but I don't really care to try. :thumb3:

I get about the same. Add 3% (for difference in 265/70 vs 285/70) - so you're getting about 16.3.

Like I said I get the same. I have the exact same tires and about 300-400 additional pounds (bumper, sliders, skids, gear in the back)

I never get a chance to go on long road trips - so the longest highway runs I get are about 10-15 miles. If I took some road trips I could probably get the MPG # up to 16-18. I currently do about 60% city and 40% highway and go around 80-85mph if I'm on the highway.

I did take one road trip a year or so ago and kept the speeds down below 70mph. I reset my tripometer and was in the mid 20's for about 90 miles.

If he crapped his pants seeing your 15.8 mpg, I wonder what he would do if he saw my 13.5 mpg :lmao:

I don't think our brakes have much of an adaptive feature, maybe it's all in your head? Did you happen to drive around in another vehicle with really poor brake feel while the 4runner was being serviced?

My 80 series. That may have something to do with it.

Speaking of crapping yourself, it gets 7-8 mpg.

13.5 is still pretty good. I have been averaging 12.4 mpg for the past 3 years.

Curious how you come up with these numbers?

City 21-22? I call BS on this unless you're pushing it half of those miles. I doubt you'd see this on the highway.
 
Ever driven through WY and MT? There can be a 20-30 mph wind at any given time. I'm driving from denver to williston tomorrow, I'll let you know what I get.

Then once I get off my ass and update my logs, I can let you know exactly every tank... but im currently sitting at 20.6 with two trips up and down I70 west of denver and through the front range.

Also, I use premium as my compwny pays for my gas.

I've experienced the same with my brakes. I've been racking my brain for over a year as to why the feel changes every now and then. It's usually in conjunction with a dealer visit. And no, I'm not imagining it and its not the position of the seat.

I was just driving home from a high school graduation thinking of the thread I was going to open up about my new and improved brakes when I got home. I saw yours and couldn't believe what I was reading. I have had the exact same thing happen with my brakes. Wednesday morning as I was leaving for work and almost locked up the breaks at the end of the street. Gone was the usual mushy break pedal and hello short pedal travel with a nice firm feel.

I've been driving for the past two days struggling with the new and improved braking action. I'm still getting the squish sound when stepping on the pedal, but the travel is cut in half and the pedal is nice and firm. I had the truck in for its 15K service on Monday morning, but there was no change after the service, just suddenly Wednesday morning it was what I would call "normal" versus the 3 or 4 inches of mush before getting any braking action. It's taken me 18 months to get used to the brake feel of the 4Runner and now I'm struggling to re-adjust to a more normal brake pedal.

I have no explanation for the change, but it is dramatic and very noticeable. Anybody got an idea what's going on?
 
has anyone heard about how when you take your vehicle to the dealer, things magically just feel better, the responsiveness, power, brakes, just drives more sturdy and planted. well i've also heard that it can be a mental thing. that you THINK everything feels better.. do anyone of you suspect that that's the case here? i'm not saying any of you are lying or anything.. i'm just clarifying that if you know about this, maybe you have ruled that out.. or know that has happened to you before.. or just, to think about it? that's all. lol

my thoughts exactly about the brake feel.. my girlfriends pontiac feels amazing when i drive hers.. then i get back in the 4runner and i'm like WOOOOOOAH DADDY! Slowwww Down! hahaha


BTW I GET ROUGHLY 16.4-16.9MPG combined driving with 285's and mild lift
 
Definitely not in my head. The change is dramatic and very noticeable, to the point of having to adjust use of the brakes. I haven't had the opportunity to test the panic breaking feature yet, but it feels like it wouldn't have a chance to kick in since I'm getting strong break force with just a couple of inches of pedal travel regardless of how fast or hard I hit the brakes. It almost feels like I've got a stuck caliper that's cutting down the necessary travel of the pads to rotor distance. Again, I have no explanation for what's going on, but it definitely is not in my head.
