Tundra brakes on a fj40

[mooker82]

The Icon doesn't use anything Toyota except for the frame and that is it. The axles are either Dana 60 or 44 based.

Doh...I did see some upgraded rotors and calipers on TLC's site. I just assumed they used them on the Icon. Did not know they were Danas.

*Don't know first hand* but I think the mounting bolt spacing on the newer ifs brake caliper (96 and newer) is different (wider) than the earlier ifs. So it wouldn't be a bolt on fit for a solid axle knuckle.
Post up if you find out otherwise.

a 7000LB FJ40? Sure you don't mean kg? I gotta see a picture of this.

Judging from the lack of meaningful responses, it sounds to me as if you are in unchartered waters. Goto a well-stocked auto parts store and have them set both calipers on the counter 4 U 2 compare.

Wouldn't 7000kg be like, 15400 lbs?.....now that would be a heavy rig!

yea, we're talking dump truck-sized brakes. good catch.

still not sure how you come up with 7000LB. Have you had it weighed?

Per Curb weight - Wikipedia, the free encyclopedia 'curb weight' is defined as "the total weight of a vehicle with standard equipment, all necessary operating consumables (e.g. motor oil and coolant), a full tank of fuel, while not loaded with either passengers or cargo."

curb weight: 3263LB per FJ40 Specs
gas: 37-18.5 gal (stock capacity)=18.5 gal X 6LB/gal=110LB
water: 18gal X 8.3 LB/gal= 150 LB
2 batteries: ~100LB
engine: -200LB from stock 2F
battery, drivetrain: negligible difference, if any
winch: ~200LB

So, you have 3623 LB plus the fridge, tent and radios. No way they add up to 3377 LB. If the mid 90's 4Runner caliper with (4) 40mm pistons won't stop your ~4000LB truck you got other problems like a bad booster, mastercylinder, seized caliper pistons/wheel cylinders, pad contamination, etc

Like I said. Fat Bastard!

Just for reference, with my hardtop on, a winch on front, 33"
tires and a Metal Tech OEM style roll bar, my rig weighed in at 4240 lbs. I can easily add another 500-800 lbs of camping gear in the back and on top. That puts mine over 5000 lbs. on a "normal" camping trip. I think 7000 lbs is a lot, but not beyond belief depending on what gear you are adding.
