It's Tuesday, and I'm about to head south for a day. I pull the bus out of the garage, go back to close the door, and notice a trail of goop tracked through the garage. Further inspect of the trail leads to the rear tire, which looks like this.
One the drum has move forward enough to remove, take it off and you will have this glorious scene, hopefully without the brake fluid all over.
Remove the spring clips in the middle of the brake - the ones that connect it to the backing plate. It's a quick turn of a small piece of metal, and the springs are free.
Use a screwdriver and pry the lower part of the brakes off the adjusting stars.
The brakes should be free enough to remove the rest of the springs, and take them out of the brake cylinder.
Remove the long springy cable that allows the parking brake to work.
Finally, disconnect the brake line from the rear cylinder and remove your dead brake cylinder. I use the little black bleeder valve cover to keep the brake fluid from leaking over the floor.
Your naked backing plate should look like this.
Put the hand brake lever back on. It will look like this when you are done installing it.
Bolt on the new brake cylinder, put the star adusters in, and put brake shoe that is connected to the hand brake in. Connect the hand brake Make sure the slots for the brake shoes are vertical, you don't want to have to monkey aroung with alignment after the springs are attached. Put the return springs one. the long connected one first, then the small lower springs second. Place the second shoe in the star adjuster first, and use the screwdriver to pull the top of the shoe over far enough to place it in the brake cylinder. Attach the center springs.
Note: the lower return springs will have one spring facing in, and another facing out.
Bask in the glory.
I'll write up the rest tomorrow, when I actually finish the job. For now, I'm going to sleep.
