    Mjp2 did a disc conversion.

    He hates it and it stops worse.... Its no secret, do a quick search and I'm sure u will find a dozen threads on it.

    Slam on ur brakes as is..... They work pretty damn well.... Disable the abs and they work even better for some situations.

    I wouldn't mess with your factory brake setup especially if its your daily driver.


    I did a disc brake conversion on my trail rig/Jeep - which - we had swapped Dana 44's under it. The Dana 44 rear drums were horrible and the ebrake never worked properly after countless attempts of rebuilding things. The Jeep just about rolled itself off the trailer one day. The disc brake conversion was a kit and we also changed out the Master cylinder & proportioning valve. The brakes were much better after that..... With larger diameter brakes on the Dana 44's, we needed a little extra something to help. When you're on Schoolbus Trail in Tellico on a steep incline, its really really important to have brakes that hold the jeep in place!!!

    For a daily driver....I wouldn't mess with a thing!!

    TW Member: MJP2 did a conversion on his 2nd gen race tacoma many moon ago (2-3 years). After many head aches, frustrations, lots of $$$, the consensus became that

    -Yes. A rear disc brake conversion is available
    -Yes. A rear disc brake conversion does work, but not well...
    -No. It does not perform better than stock
    -It is immensly difficult, to near impossible, to make a rear disc brake conversion work correctly and properly with the stock OEM system and even an after market system, even more so with 09+ electronic system.

    Basically, don't do it. Just upgrade your front pads and rotors, change your lines to SS you'll see a minor increase in brake performance. The pedal will still be spongy regardless of what you do.

    What about just dropping in a rear end from an FJ? Wouldn't that make for an easy swap?

    Racing a 4X4 truck on a track with lots of turns seems kind of slow some how but that maybe where you could gain some thing by switching to disks they do get rid of heat quicker don't stop any faster and are way expensive but yeah go for it they look cool.

    Good to hear, because even though I prefer working on disc brakes, the late model OR brakes are impressively strong. Be glad your truck stops as well as it does. :cool:

    Among other things, it is much more difficult to incorporate a parking/emergency brake with disc rears. Loaded trucks need lots of braking power when parked on a slope. Many vehicles with rear discs still have a drum parking brake.

    Most vehicles don't benefit much from discs in the rear. Most vehicles have something like an 80%/20% Front/Rear braking bias, and a truck has even less weight in the rear, so your rear brakes are doing like 15% of the stopping. Also, drum brakes are cheap and generally reliable.

    Spring perches aren't that tough.

    I have been wondering about this myself, you get the drum in disk E-brake which is the biggest advantage I see over a rear disk brake kit. Does anybody know if they are the same WMS?

    I have been daydreaming about running a centered FJ80 rear axle which is full float drum in disk and 9.5" third member, I don't know if the abs sensors would be compatible.

    Why reinvent the wheel? The brakes work great, they have used the same set up for ever if it ain't broke don't fix it. Disk e brakes are small drums inside of the rotor or on the caliper and that type eventually froze up and wore the pads out. The K.I.S.S. principle works fine for me.
