4 wheel disc
 
Hi Guys
I want to put brake disks on the back of my 04 wrangler. Are there any interchangable parts off a grand cherokee or others that will work ?
I have priced the kits, they want a small fortune for them.
Any ideas --- Thanks

What would be the advantage to a rear brake disk vs a drum?

rear disk provide better stopping and are more reliable.

They are the same reliable if both are maintained and the same is true for stopping ability.

I don't know what you consider a small fortune, but we have rear disc conversions for the Dana 44, 35, and 8.8 for that matter that are sub 400 for all new parts except for the high quality reman calipers.

I don't know if you have the 35 or 44


D35 Disc Brake Conversion - 1 -35

Disc Brake Conversion - 1 -44

i would argue to say that they are more reliable. I think people have more problems with drums because they are afraid of maintaining them. lack of maintenance means more problems. and drums really are not that bad once you do them.

i think disks are marginally better at providing better stopping. but compared to the large price for the conversion kits i would use my money else where.

heres a thread about disk breaks vs. drum breaks:

Big misconception there. Rear disk brakes stop no better than rear drum brakes do. Really. Neither are they more reliable. Disk brakes are easier to work on but that's about it.

The only benefit you'd notice after converting from rear drums to disk would be ease of maintenance. You certainly won't notice any improvement in braking.

Not to mention that the rear drum brake performance has to be limited by the brake proportioning valve to prevent the rear brakes from locking up too easily. When you brake hard, the vehicle's weight is thrown onto the front brakes & off the rear brakes. So the rear brakes can lock up much more easily in that situation. If the rear brakes are allowed to brake too hard, they will lock up & cause a skid. So even the drum brake's full potential cannot be used when on the rear. Making the rear brakes more powerful will just encourage them to lock up & throw the Jeep into a skid... which is why the brake proportioning valve is there to reduce how much braking force the rear brakes can provide.

Just to add to what the others have said. If you maintain and PROPERLY adjust the rear brakes they work surprisingly well. In my experience they also last much longer.
