View Full Version : What tools do I need to remove the rear disk brakes?

There are several late model 2500’s in out tank salvage yard over here. Most of them are 2005 and up. I want to pull the rear disk brakes off of a few of them. What tools will I need for that? I need the specific tools and only the tools required. I will have to borrow them so I can only get the ones I absolutely need. I want to pull the bracket, caliper, and rotor. Will I have to remove the hub as well? If so, will that require a special hub socket? Also, if any of you have any photographs of what all is involved, that would be a big help. I have never messed with one of these AAM axles or a late model Chevy.


Thank you for your help.

This is one example of what I will be working with.

no u dont have to pull the hub just the pieces u described.i believe the bracket the caliper bolts to is held on by 2 bolts which u will need a 18mm socket for. the caliper bolts or slide pins are 15mm i think but not entirely sure on that one

Thanks. Knowing I do not have to pull the hub is a big help. I am going to try and head out there this morning to get them.

I did mine on an '01 K2500HD; no, to replace the rotors you don't have to pull the hub from the spindle. However, if you intend on replacing the parking brake shoes it may help. There is a special spanner socket used for adjusting the tension on the outer hub bearing however.

Does your hub seal leak (either side)? My left side req'd replacement; I understand this was a common problem.

I went out yesterday and tried to pull the whole assembly. I was unable to because my forklift broke. So I had the operator take it to the shop and I pulled the hydroboost instead. From what I saw, the hub does have to be removed. If so, I may has well hang it up. I was thinking about pulling the whole rear end and taking it some where I can work on it over time. But with out that tool, it will be a wast of time. Does any one have the part number or manufacturer of that tool?

I was going to post photographs, but the site will not allow me to.

The socket is needed for assembly torque. [I don't recommend this] It can be disassembled with a punch and hammer, if the need arises. A piece of 3/8-1/2" round stock can be substituted for the punch. It'll need to be 8" or longer. Both sides are RH threads.

So after I pull the axles, all I need to do is pull that hub nut and I am done? If that is the case, I can still pull this off. I did not realize the rear hubs came off that easily.

It isn't "that easy", so to speak. The punch can be used to loosen the lock nut (chisel it around, not cut it). If all you are doing is robbing parts, and don't need to salvage the nuts, you can do it w/o a socket. That's all. It's a matter of convenience, and will usually damage/destroy the nut (or the hub/bearing if you miss).

Once you remove the hub nut, the hub and bearings will come off. The E-brake may hang up if it's adjusted tight or rusty, but it will come off with enough "persuasion".

Just curios, but why are you pulling a "few" rear disk brakes?

Also, if you can salvage the E-brake shoes and hardware (if they're in good shape), you may want to collect those, as well. They are very pricey (3X more than the service brake pads).

I got a good look at it the other day. The only things I am not taking is the rotors becuase they are damged. It looks as though the truck was pulled with no rear tires or rims. I want to perform some rear disc conversions when I get home. So if I can pull these parts that have few miles on them all it will cost me is the shipping back to the states. And if I spread it out for a while (becuase I will not be going home any time soon) the boxes will not be that heavy.

I am pretty sure I know what you are saying about the hub nut. I have had to use a hammer and puch to take apart fron hubs before. I prefer a hub nut socket. But sometime you have to work with what you have on hand.

She shipping will sick, but it will still be a lot less then buying a bolt on kit.

All I was able to get today was one rotor and one caliper. I pulled the axle and the hub nut came out with my fingers. But, I cannot get the hub off now. Plus, one 24MM nut is in such a tight place I have nothing that will work. I have to try and locate a very long box wrench.
