Default Rear disk brake conversion

My rear brakes went out on my truck. Pulled the drum apart to find every thing all messed up. Drum is worn alot, pads shot, wheel cylinder over extened, etc.

Rather then spending the money to fix the drums i figured that i would convert it over to rear disk brakes. Never have liked my drums and they have never worked very well and if my axle starts leaking the pads are no good after getting gear oil on them. Just tried of them.:chiefwoohaw:

My question is if any body has ever ordered from sky-manufacturing. If they are relieable or not and how quick they will ship it out.

I can get the right rotors, the caliper brackets, and the conversion lines for $260 before shipping. Thats real good price compared to downey and other places.
Just stroll down. Its about half way down.

Or have you ordered the kit though any body else. Or even made your own. Just looking for people exspence with rear disk brakes on a toyota truck.

SKy is very reputable, yes. I have some of their parts on my truck, and in general, they have a good rep.

I think its cheaper to just get the brackets, and source the calipers and rotors yourself, but its certainly more convenient to get the stuff as one kit.

I'm about to put the same rear discs on mine.

i have the parts at my house waiting to go in my truck right now the brackets are nice. i have just sourced the other parts locally to do the swap mid 83 early 90s fs chevy rotors that need centers reboared to fi rear axle break lines from the same truck. and the calipers are out of a late 80s caddy eldirado with parking breaks. ill have under 200 in the whole set up once done. sky has been the best dealer i have dealt with wile ordering parts for my build. i had my parts with in a week except for parts that were on back order. They were having trouble with one of there vendor for spring bushings.

Haggar, I think you are being ignored, and apparently, these people are not smart enough to look at dates

Hehehe.

For what its worth, on a toyota, I like the stock front brakes mounted on the back.

I got brakcets from a guy on pirate4x4 (search the toy forum for a brake thread started by muchado).

brackets bolt on, you need to put the rotors behind the axle flange, which is a little bit of a pain, but they work well, and were free(when you replace the fronts for better stuff)

Then run FJ40 and late 80s 4 runner calipers up front. Better brake biasing than a lot of the discs out there. And fixed calipers in the rear let you run hard lines to them, again less money.

Haggar, I am planning on doing exactly that on my 88 4Runner..was wondering though, why the FJ40 rotors? if using the 4Runner calipers, why cant I use the 4Runner rotors? I havent gotten that far that I have tried lining brake parts up yet, but was curious and havent seen any answers to this anytime I have searched the various websites

I have been out of toyotas for 2 years now, so forgive me if I forget the exact details. But I believe the IFS rotors are smaller diameter. The calipar mount is further out from the center of the rotor on the solid axle. So if you use the IFS rotors, then part of the brake pads will be just in the air, not touching the rotor.

The FJ40 rotor is venter, but matches the diameter as the solid axle ones, so the caliper mount is in the right place.

For this reason, using the large 'V6 style' calipers (they have ribs/fins for cooling cast into them) on a solid axle truck often requires you to clearance them lightly with a grinder to clear 15" wheels that would have fit fine on an IFS truck.

I had to cleanance mine a touch on basic steel 15x8 wagon wheels with 3.375" backspacing.

thats kinda what I was thinking but wasnt sure...so the IFS calipers just bolt right up on the solid axle? the caliper mounting points are just pushed further away from the pistons, compared to the solid axle/solid rotor calipers?

I guess I could get off my lazy ass, walk out the barn, and look at the parts myself...but I'm lazy

Yep, they bolt right in.

What the advantage of this setup, is the 'Big' calipers have I think about 40% more piston area than the 'small' calipers. so using bigs in the front and smalls in the back help build in more front brake bias. So less work you have to do with a proportioning valve.

Lots of people use chevy single piston calipers and K-truck rotors in the back, those end up being more piston area than the toy fronts, and really need to be knocked down with the prop valve to be safe in emergency braking.

Granted, the chevy parts are a little cheaper.

done the chevy parts for rear disc before...was never very happy with it..as you said, the rear was braking too heavy, almost made it seem as if the front wasnt working

I'm looking at this kit for my 4Runner.
Add in a proportioning valve and a line lock - Good to go !
It seems to be the most economical.

Great Tip Never considered using the stock fronts on the rear. That means you need to buy separate rotors and pads though. That kit rocks I could see myself going with new rotors/calipers and that kit on all 4 for under 2k.
Anyone done this or have a write up?

Have a set of 87 fj60 axles that need a (cut&turn/ breaks and a refreshing) running the stock setup and 4.11's that will be going under this 69cj5 after the tube frame/body are bent. Currently saving up the 3k for a shop to make me the tube frame while I design it.

Plan on retaining the current e break on the transfer case(uses the diff ratio for more holding power and keeps cable high).

Kind of wondering what power booster works best with what caliper in this setup? Believe it or not if I could go stock I would actually prefer it(so I could find replacement parts in say 8 years).
This thing will be a daily driver when it is all said and done. Still see myself using a proportional valve of some type and really shy away from any ABS. Something compact comes to mind as the hood/fenders/wheel wells are going to tilt forward leaving the engine bay open. Having a booster as far back as possible means more room to work and reach things. But I also want one that can perform great when I need to stop from 70.

Most people run the dual diaphram boosters from various toyotas. Lots cars and trucks had them, I got mine from a 1988 Supra. Some of the T100s had them as wellThe MCs bolt right on. They are pretty reasonable diameter, smaller than the single diaphram ones.

No idea if that will going into an LC without fab work.

I got the Trail Tough Econo Kit.
So I'm gonna buy new Low Range Offroad Bearings and Cups, and do the mod the easy way.

But, I'm going to change the way the rotors mount - so they can be easy on / off - and not have to pull the Axles to change the rotors. Small spacers - and it should be good to go.
