4R Rear Disc Brake Conversion

[tx_shooter]

Besides the obvious ease of maintence and increased stopping power; are there any other benefits to going to disc brakes on the rear axle? I have already come across known issues with the e brake; anyone know of any other issue with going this route?

Sky makes a kit to solve the e brake problem. Adds it to the rear of the tranny with a disk, we have the same type on our buses so I know it works well.

Are you talking about the transfer case kit?

I guess, its been awhile since I looked at it. I know it bolts in the driveline and works with a spring etc that mounts on the frame.

This is what I'm going to run since I have no e-brake currently.

The reasons you mentioned are the basis for the upgrade. Pirate has a ton of info on this.

Upgrade the front to tacoma or ifs rotors and calipers and move the front rotors to the rear (machine out hub to clear) get necessary bracketry and so forth.

My stock brakes suck when wheeling. I have to use a ton of E-brake as well on steep obstacles

That's it.

Pirate does have a ton of info - some of it old as dirt that may or may not apply anymore with current kits. They also have a lot of bullshiting too.

As for the Tacoma rotors up front; why not run them in back also?

Thanks for the e brake solution Keith (and Blake for the link).

Interesting kit. Defintently add to the cost some - but you would have to have a solution for an e brake I guess.

increased stopping power;

Technically, drum brakes have more stopping power. Though I would still say discs are better.

I had the upgraded to IFS front calipers with FJ60 rotors, a 1" bore MC and SS brake lines on my 4Runner as well as the e-brake kit from Sky. TrailTuff sells a kit to utilize the original non-IFS calipers on the rear. http://www.trailtough.com/index.php...n=com_virtuemart&Itemid=53&vmcchk=1&Itemid=53

But even with all that it still didn't stop great. The Raisin has IFS calipers/LC rotors up front and GM calipers/vented rotors out back and it stops 2x as well as Clyde did.

My solution on the Raisin is a mechanical line lock. But for now I just put it in low-low-low and it doesn't go anywhere.

MJP2 had issues with discs on the rear of his Tacoma. Could have been the kit he used, but I will try to dig up some info from him.
