I just want to clarify this point, as "DOT4 or better fluid" implies that you would be fine, maybe even better off putting DOT5 fluid in your brake system.

YOU DO NOT WANT TO DO THIS.

DOT5 fluid is not compatible with DOT3/4 systems. If you try to do this, you will have major headaches. Even draining all of your DOT3/4 fluid and replacing it with DOT5 is not a good idea.

I am happy with the brakes on my truck(93), over 100,000 miles on the original rotors. They have been turned once to remove the grooving but they have never warped. I think the 2nd gen brakes must be better than the 3rd gen.

I'm assuming that this would work with a 3rd generation 4Runner as well?

DrBeau

...so yeah.

Umm.....

Basically, you're going to remove your stock calipers and rotors, grind down the inside half moon of metal near the caliper on the dust shield (about 1/16 - 1/8th of material).

inside half-moon? are you talking about the caliper mounting bracket?

MTL_4runner

No, it is the dust shield.

justinh

thats what i thought he was referring to first but i couldn't think or anything that looked like a half moon on the dust shield.

another question that i have is, how does the pedal feel? did it get more firm with the additional pistons? i know that most people that do SAS's end up with a really mushy pedal because the calipers they swap (waggy or chevy) to have two large pistons.

How much did this cost?

Damn, you have to tell me this 3 days after I get all new front brakes.... Do you ahve any clearance issues? B/C my seteelies are damn close as it is. I'd probably have to go back to the stockers (which I was planning on doing anyway)

Ok, here's the pics.

In advance, sorry I can't compare them because I don't have the old discs. Grab a ruler and see if they are near the measurements I have for the width of the disc.


Measurement


Shot of disc/caliper


Shot of caliper from backside. This is where you will need to trim the dust shield. (between the 2 19mm bolts that hold the caliper in place)


Shot of the OEM pads



Price - What I paid and what you might pay are going to be compeletly different. I got a deal because my buddy wanted to see if it worked, so he hooked me up. I paid for new pads and some shop time, but otherwise that's about it.

Search your local junkyard and see if you can find some 2000+ Tundra calipers. You will also want the OEM tundra brakeline that is attached to the caliper.

Now go WRENCH!!!!

Sorry bro, if I knew you were going to replace all your front brakes, I would have told you about this.

I have 16" SR5 wheels on my 4WD, so there are no problems at all. I have no idea about steelies or otherwise. 15's WILL NOT FIT, you MUST upgrade to 16" alloys at the minimum. This I am sure of.

Pedal feel is about the same, braking is not. If I stand on my pedal, it feels like the rear end is going to come up off the ground. The truck want's to do a stoppie....

Praufet

So any idea if this will work with a second gen? Also i think brembo makes after market kits for the tundra if anyone wants ultimate stopping power.

Gangus2006

No sir! Tundras had 4-Piston front calipers

And for the person(s) who want to do a rear disk conversion with the front disk/caliper, lemme burst your bubble: Front caliper dont accomodate the e-Brake, so it wont work..

DrBeau

Well you would have to do a driveline brake for the e-brake.

justinh

if this is true then where is the gain coming from?

socal98runner

They are still 4 piston, but the stopping force is greater due to a larger piston.

Also, the brake rotors are thicker and so they have more material to disapate heat with.

All this equates to better stopping power.

justinh

you wouldn't happen to have a picture of the two calipers side by side would you?

saletel

there are 2 different kinds of dot 5 fluids, one is compatible, another is not sorry im too lazy to look this up i am pretty intoxicated

This is a shot from on top of the standard 4Runner setup:
