After searching all over the place for some info on SSBC disk brake conversions and not finding anything I thought I would drop the question here.

Has any one done or know any one that has done the SSBC disk brake conversion on an AMC 20. 1 piece axle.The directions a good but it says to see exploded view which seems to be missing from my instructions. I wanted to get this done this weekend since my drum brakes exploded last week. Ordered the SSBC kit and it arrived today. But I really need to see a pic or the exploded view to ease the install a bit. SSBC tech line will not be available until next week.

Oh yea Merry Christmas and thanks for any help.

Yes. They had a few topics about disk brake conversions but no pics of the SSBC on a cj.

How about a parts list,What calipers and disc.Are these adapter plates?
You know that the master has to be changed to accomadate the calipers.Residual check valve.The rest is figuring out the bearings.I,ve done a few conversions and it shouldn't be to hard to figure out.
Is that Stainless Steel Brake Products?SSBC?

Merry Christmas,D.G.

Im sure I can figure it out. The instructions have enough info. The missing exploaded view would be a big help. According to SSBC the master cyl and prop valve should work.

If you have drums now and are going to disc I really dont think you can do it w/o a new master.The difference between a master cyl. is the residual check valve built into the master.this alows for the proper bleed back as the caliper and the wheel cyl's require different pressures.(alot more volume on a caliper vs a wheel cyl. and runout becomes an issue.its an easy fix,just get a disc brake master for your cj,I think there was factory disc?Dosent matter there's a million that will fit(common bolt pattern)all you have to consider is what side the lines are on.And power or not and thats easy to.

What does the 4 disc setup do for the money?

The disc/drum setup gives better stopping power than 4 discs, and is simpler to maintain.

The 4 disk setup is suppose to be much better than the factory Disco / Drum . Drum brakes fade when wet and take much longer to come back. My main goal is to improve reliability. This is the 3rd set of brakes in 5 years. I have warped the drums and destroyed the rear brakes and just flat out lost the rear brakes on many occasions. So this time I need a new backing plate and replacing the backing plate is a real chore on a CJ withe the 1 piece axle conversion.

As far as master cylinder goes. SSBC says the factory is OK. But I am prepared to tackle the issue if it turns out to be one. On a couple of forums they talk about removing a valve in the master cyl. If I'm not mistaken the disk brake uses less volume to work the brakes the volume of fluid is greater but the caliper does not need to move as far as a wheel cylinder. It will be interesting to find out. one issue could be running out of fluid in the master cylinder due the the increaes in voulme and the much thicker pads. I will need to keep an eye on the fluid level. At some point I plane to add a brake booster and new master cylinder. Just hadn't planned on that right now. But ready to do it if need be.

Yes it is SSBC. T dird pads in lincoln calipers I think w/built in park brake. 11.345 dia. rotors. Havn't figured out if they are custom or an over the counter item.

Stupid me,I thought the front brakes were being converted,The master might not be an issue but disc don't have return springs so they depend on runout to not drag.Volume is gonna be an issue as you stated.Like you said it might be time to get a booster.Let us know how it works out.

Merry Christmas,D.G.

Will do D.G.

Good morning and thanks for the info.aaaaaannnnnnnd........MERRY CHRISTMAS

Make sure the parking brake stays at the rear wheels, and not on the driveshaft in case you break an axle/u-joint/driveshaft. Certain set-ups will increase your un-sprung weight. It's odd to me that most of these conversions are done to improve the brakes on a vehicle that has had little attention paid to the drum brake set-up over the years. Before the disc brake conversion became available, we used to install Wagoneer drum brake set-ups. These guys have conversions, but it is possible to convert with salvage parts. http://www.quadratec.com/products/pr...sion&submit=Go

I have no experience with SSBC brakes. I ended up swapping out the rear D-35 axle in my Jeep TJ with a Ford 8.8 from an Explorer. Rear disc brakes are pretty much identical with the Grand Cherokee, so I used '96 to '98 GC part numbers to re-build the Ford brakes, including the e-brake. I made no changes to the master cylinder and they work great! There are several good Jeep forums out there beside pirate4x4. I used to be on jeepsunlimited.com, but there are others, too. Vanco I think is another company that specializes in Jeep brakes, but you might be limited with that Model 20 rear axle.

Thanks for the reply. Man I have been looking at so many forums I am going blind. I am going to call the SSBC teh line monday my plans to get it done today were spoiled by not having a new set of bearings and seals that were suppose to be in the kit. None of the local parts houses had them in stock (bearings). TK SET9.

I have so much invested in this AMC 20 I hate to swap it out just yet. Lockers ,Superior axles and such.
