G2 Axle & Gear Disc Brake Conversion Kits

This is a very nice kit to install disc brakes onto the rear of your Jeep. The Jeep I put these on is a 2001 Wrangler with the factory optional D44. The install was straight forward and went very quick. It came with braided flexible hoses which was nice. The calipers also have a very nice looking finish and the rotors were slotted. There are some things to keep in mind though. First is that you will need to press the bearings off the axle shafts to install a required spacer. It is not recommended to reuse the bearing lock collar so you will need to buy new bearing sets because I don't believe there is a way to get it separately. With the C clip style axles I don't believe this is an issue. Second is that the brake hose brackets are to be welded to the axle. No sweat if you have a welder of course but if you don't I don't know what you will do to attach the bracket. It would have been nice if the brackets could be attached with some hose clamps at least temporarily. That way you could safely drive it to a shop to have the brackets welded. Any muffler shop could do it quickly and inexpensively I'm sure. Finally 15 inch wheels are a very tight fit. The stock steel wheels wouldn't fit at all and my 15" Ecco wheels rubbed very slightly. I ground the calipers slightly for clearance and they now fit nicely but there would have been no way to get these to work with the factory steel wheels. If you can run 16 inch or larger wheels that would be best. Also don't forget to add in the cost of new parking brake cables. The Teraflex cables are $45 each but some OEM cables from a Grand or a Rubicon may do the trick for less. Over all a very nice complete kit.

In order to install the spacer ring (because the backing plate is thicker than stock) you will need to pull the bearings off the axles. When you do this you will ruin the bearing, retainer and seal. If you buy Spicer parts you are in for just over $100. You will also probably need someone to remove the bearing and press on the new one, IT IS NOT EASY. If you want to have a decent pedal feel you will need to replace the Proportion Valve for a disc/disc setup. The least costly route is to re-plumb the master. Put a T in the front brake lines and buy an adjustable PV for the back line. You will find the fittings to be a challenge because they are a mix of SAE and Metric. You will need fittings, brake line and a flaring tool. My setup is with 35 in tires which has its own draw backs on the braking system. My opinion is the disc kit was a waste of money and time. If you have 35 inch tires and want better stopping power you will have to change out the front disc's for something more substantial. Don't fall into the replacing master cylinder game. The master in a TJ disc/drum is the same as Rubicon disc/disc.
