Transmission Brake Pre Assembly

Brake Expander

The four small photos show the brake expander being assembled. I’ts a pretty simple little mechanism. I can't imagine much could wear out. So just a clean up and grease up and ready for installation.

Brake Expander Clips

The three little clip things are the overly complicated way the brake expander is held onto the transmission brake backing plate. I suggest taking note of the order that they come apart (I sort of did, but not well enough). They go together in the correct sequence, each locking the next in place, while providing a ledge to stretch the rubber boot around. It’s possible to put this together wrong, but sort of seems OK, until you try to put the rubber boot on. I had to look up the part numbers in google images to figure out the correct sequence.

Brake Shoes and Springs

I reused the old shoes. They were covered in oil when I took them out, but I cleaned them with Braklean and gave them a cycle in an ultrasonic cleaner. I would have replaced them if they were part of the main brakes, but really the transmission brake is just a complicated clamp, so they'll be fine (I reckon). I always leave my vehicles in gear anyway.

The brake adjuster is at the top. It’s a simple little mechanism. I disassembled, cleaned and greased.
