John Nicholls had a problem with the left center drum over heating. he found the following problem. i tried to upload the photos to the photo site but was unable to connect. i will try again. John said he ordered shoes by the part number in the GMCMI parts list. are there other shoe numbers available?
""The emergency brake lever is capable of being installed incorrectly on the rear brake shoes. I recently encountered this issue. Ken Frey and Stephen Galovic co-authored an article for the December 1992 issue of “Motorhome Marketplace” which documented and described this issue. If installed incorrectly (as I did), the shoes remain spread affecting wear and emergency braking capability. Photo “brake shoes wrong” shows my new work installed incorrectly (to high) and the photo “brake shoes correct” shows the correct installation. There is one other mismatch where the lever is installed to low.
The issue is with the brake shoes. It looks like there are 3 different configurations of shoes. The difference is the dimension from the triangle slot where the emergency lever hooks into the shoe and the slots where the emergency brake strut fits the shoe. on some shoes the slots in the shoe are too high and in some the slots are too low. the pic's show the correct and too high installation. the only way to correct this is to get the correct shoes. it doesn't look like the problem is with the lever it is with the shoes themselves.
