[AT] de-greasing disc brakes

[Thomas O Mehrkam]

About five years ago I replaced the rear pads on my F250.

Shortly after that the rear seal leaked.  The pads on one side was very 
greasy.  I replaced the seal and decided to try to salvage the pads.   I 
just used a couple of cans of brake clean alternating with clean rags.  
The grease appeared to be gone.  So I tried them out.  Still going 
strong 70,000 miles later.  I even towed an 8000 lb trailer over most of 
the high passes on Colorado.  No brake problems. Good even breaks.

Of course the grease was only on the pads for about a week the pads were 
Wagner Super duty and likely different material than yours.

However, 4 disc brakes to fit my combine will run me $450 from Deere—they are not available aftermarket—it appears the 3300 was the ONLY thing to use this particular transmission. I’ve got plenty of pad left on them. I had a light leak/sweat on one side, the other is dry. Anyone ever had any luck degreasing a set? As stated they weren’t really greasy, but they just have a look and feel that to me suggests at some point they have gotten grease on them. I’m thinking about soaking them in Purple power for a couple days. I washed them off with Gunk yesterday.

Installed new balls and springs. This time I am going to try re-machining the 2 steel pcs that actuate the brakes as I can tell they are not wearing flat. I’ll hand sand the discs on a ground plate or surface plate—yes I know they are probably asbestos so I’ll take reasonable precautions. I’m also going to replace the seals in the transmission.
