I was doing a reserch and apparently 4runner brakes with 4 pistons (non sport) version fits on a gt front rotors, And the sport version fits gt4 rotors. I think the brakes have to come off from a 95-02 3rd gen 4runners and will bolt on perfectly with no modifications.
Now my question is if they fit proportional valve needs to be modified? Becsuse it will be pusshing 4 pistons instead of 1.
If anyone has more info about this please post it here.

Are you serious?


Yes, I am - the brakes are the most important system on your car - the effects of modify the brakes will greatly alter the characteristics of the car above and beyond any other change.

why do you think its considered a brake upgrade when cars like STI's, EVO's, Porsche's, Ferrari's, etc... have multi-pot caliper brakes?


It's not - It's called stock, i.e. a caliper specifically selected for that car

as far as braking faster, its still to your advantage. its always been considered an advantage to stop sooner, as far as ending up under someones backend... Who cares? better than smashing into it evenly, and if you're in a lowered car its likely you're gonna end up under it anyway!


No one is questioning the straight line stopping advantage of larger brakes (which is the end result of those 4Runner 4 pots, 4 pots in general will not guarantee greater stopping force for the same size caliper) A 1" lower is not a 3" dive under the bumper of a F150 instead of crashing into it... I would care when I have a greater chance of kissing the rear end of that truck with my teeth.

furthermore, front brakes do the majority of your braking anyway, so as far as going ass first into a guard-rail; you've got much bigger problems if the backend of your FWD, Front Engine car, with a ~60/40 front/rear weight ratio... is sliding ass first into a guard rail.


Yes, they do... but the weight shift to the front could be far worse and unpredictable with that caliper change and a poor balance tune.. My comment about be ass forward was a potential result... as opposed to recovering from that situation


QUOTE (cjh4l22 @ Sep 27, 2011 - 2:11 AM) *
your information about seizing brake calipers and master cylinders has no logical reasoning. why wouldn't your current rear brakes have that problem? they don't do the majority of the stopping in a fwd car, or any car, for that matter. most master cylinders have more than enough ability to crush any set of current day rotors and are the same ones used in gt4's and in some (much heavier) toyota camrys, so why wouldn't it work?


I don't know why it would not work. It is simply a concern and cannot be ignored when upgrading the brakes... It's a system, and you must think systematically.

oh, and late model ST165's and ST185's single pot brakes... did you not notice what they got replaced by? multi-piston brakes. yea, I'd say the manufacturers had a pretty good reason for that IF they've been doing it with everyone of their sports car since 1993. (ie. - supra, gt4, 3000gt, stealth tt, evo, eclipse, corvette, mustang... need i continue?) So yes sir, it IS most definitely a flipping upgrade!!


Sure, its an upgrade... it was also a designed change, made in the context of the rest of the vehicle's brake system

You mentioned a host of cars, which are grossly out of context price and performance point wise, but my point can still be proven, I googled with zero follow up or scientific rigor:

Car / Weight / Wheel Size
4Runner ~ 3,700 lbs, ????
Celica ~2,580 lbs, ????
GT4 ~ ~ 3,174 lbs, 16x7"?
STI's ~3,296 lbs, 17x8.5"?
EVO's ~ 3,285 lbs, 17x8?
Supra ~ 3,417 lbs, 16x9
3000GT (We'll assume VR4) ~ 3,800 lbs, 18x?
Corvette ~ 3,180 lbs (17x8.5F, 18x9.5)
Mustang ~ 3,603 lbs (18x8.0) -> 19x9.0

I'll skip the ferrari's and porsche's as they are a bit out of the scope of the discussion.

These cars all demonstrate a convincing need for the brakes selected for the car... to a car, they are all well over 500 lbs heaiver and significantly more powerful, even with the 3SGTE swap. They also have larger and wider tires to give you a larger contact patch to use those brakes....In addition, these cars are all halo cars to their respective brands, many of them the bench mark for stock car 'Ring runs, et all...

You guys are all right... you drop those 4Runner calipers on, and your 100-0 stopping times will be greatly improved, probably markedly... but at what cost? a bias valve is not a Jesus buttom, its not going solve all the system issues. In the end, people talk all the time about upgrading the calipers, and no one here talks about what it means to add 5-10 lbs of unsprung rotor weight out on the corner of the car like that, what will that do for acceleration, are the brakes the limiting factor? or is it the tires? the pads? worn out shocks and struts? what happens to handling, etc?

I want to have a tecnhical discussion about it, and it just turns into a flame war, how dare you question my plans, you hate america, blah blah blah - so whatever. you have the means and the way.


QUOTE (cjh4l22 @ Sep 27, 2011 - 2:11 AM) *
So, in short... If you prefer taking more time and distance to stop when its necessary... and feel like smashing into someone, then by allllll means sir. enjoy. we will send you a card while you and you're passenger are in the hospital. good day.


Any question wrt your class is nicely summed up here... Is this how you end all technical discussion?
