4runner calliper conversion worthiness?

[LT1-62]

Oh gawd... I can't spell half of the names of the cities. North Island mostly.

Some in Rotorua, some in ophonga (I know I butchered that one)...

haha Rotorua yip, and Owhanga? Google tells me that place exists but damned if I ever heard of it, must be tiny. You guys would love it over here, everyone always complains that the downside of Toyotas is part availability, whereas over here Toyota parts are probably easier to come by than any other car company bits. Its the Chevy parts that I cant get my hands on...

 

[Doc]

Yeah- Owhanga.... I tend to spell phonetically, so it comes out differently. There's another little town we visited, ends up being pronounced phongerai... so it must be spelled whangeri or something similar...

Native names give me the fits.

The biggest problem I have finding parts is finding the money to pay for them all!

NZ sure is a pretty place though. I wouldn't mind moving back there. I went for a couple of hikes in some of the forest there.. it's very primitave. Very cool. Unfortuneatly for me I'm allergic to wool, and that doesn't go over well in that country!

 

[LT1-62]

I believe the place you are talking about is Whangarei, in northland. Yes there are some really cool old forests to explore, big podocarp forests with some of the biggest trees in the world. There's also lots of cool 4wding to be had, although I prefer the high country stuff down here in the Sth Island. Dont think being allergic to wool is a good reason not to come visit, most of it is exported and it is a shadow of the industry it once was here, hell, even if you live in the country you may never see sheep cause alot of the old sheep farming has changed to dairy.

 

[Doc]

I really should go back sometime. I was only half-heatedly kidding about the wool. I am allergic to it though! My uncle runs a fairly nice sized ranch up there and had more sheep than I know how to count. He also had a few cattle, but didn't ever butcher them because they were too expensive! As far as I know he still has quite the sheep ranch. I remember being very impressed with his dogs. Really used them to drive the sheep from miles away- impressive!

Last time I visited I came back with about 8 sheep skins- when done up right they are VERY soft!

Also developed a taste for mutton while there.. you can't even BUY mutton here in the states. I wouldn't even know where to go to buy some if I wanted it, probobly a middle eastern market or something.

 

[LT1-62]

No mutton? What about lamb?

 

[Doc]

Both are very difficult to find where I live.

I can actually find shark meat easier than I can find either one of the above.

Sorry to hijack this thread, but does anyone know if there are drawbacks to going with the truck/skinner calipers and 1" master cylinder?

Is is a direct bolt on for my FJ62? I have stock rims a 2.5" Dobinsons suspension and BFG AT 31X10.5's on now, I I go to 33X12.5 MTR's on wheels from FJ60.com will I have to grind or clearance anything.

Just want to know what I am getting into. If there are no drawbacks I plan on going for it. Does anyone know if they use the same extended brake lines as my stock calipers.

Thanks,
Dunbar

Yes, it is a direct bolt on, but also, with stock rims, i believe you will have clearance issues with the rims. Some people say they have no problems, and some people say they have to grind the calipers. I guess it depends on what rims ya got and if you dont mind getting new ones! I am not sure which rims fit the calipers and what dont though! Sorry

I can't remember putting them on a rig with stock rims but I don't see any reason why this would cause a problem. You will have to snip/cut/bend the dust plate to allow for the slightly longer size of the new caliper. You need to open up the gap in the plate by about 1/2 - 3/4 inch on each end. Trim it if you want it to look nice, bend it if you don't care.
Other than that is is a straight bolt on.

I have seen where the slightly larger pistons and the resulting larger fluid requirement for the front curciut draws attention to the fact that the rear brakes need to be adjusted... But this is not a drawback of the conversion, just a reminder for maintenance.

Thanks Guys,

I will assume that the brake lines are the same for both calipers and that I will need to order pads for the donor truck as I assume they will be larger than the FJ62 stock pads.

I will gladly trim the plates and if I must slightly clearance the calipers for my stock FJ62 6" rims, of which I have 6.

Salud!

You assume correctly... see above... "Other than that is is a straight bolt on."

As far as the brake caliper hitting the wheel, two factors I can think of. The added width of the caliper body, and the caliper's position with respect to the rotor. (This fact was brought to light by an observant DTLC lister.) The rotor ends up sitting off center within the caliper. These pictures show how the rotor centerline is farther inboard than the caliper's center.

The discrepancy is about 3-3.5mm. I suppose one can make a small spacer that places the caliper farther inboard as long as there is still enough thread engagement on the bolts that hold the calipers to the knuckle housing.

I'm pretty sure that you want '92-'95 calipers to get the biggest pistons (2x40mm). I put a washer on the mounting bolts between the caliper and the knuckles' caliper mounting tabs, which spaced the caliper inboard enough to get rid of the interference with my 15x8 3.5" BS TECII Rockcrawlers from 4WheelParts...no grinding necessary. FJ40/FJ60/Minitruck calipers have 3.5" bolt hole spacing...at some point (FJ80/post '95/Taco/Tundra???) the spacing went to 5.25" (I think) between the bolt holes. '93 4WD V6 4Runner is the application that will certainly get you the 40mm piston calipers you want.

I have these on my 9/85 FJ60 with stock master in good shape, and they work very well, I can feel the extra braking power, and I notice the extra travel in the pedal, but it's fine. Extra travel means extra mechanical advantage, so you have more power available, even though the firmer pedal of a larger bore master will feel better.
