To get to the parking brake you have to remove the fan air intake screen under the tranny. On the right hand side of the tranny you will see the brake drum and speed pickup sender. There is one bolt in the center of the drum, remove it. There will be a washer, gasket and a shim that will come off with the bolt or when you pull off the brake drum. The wheel brakes are a pain to remove. If you look at the brake assembly you will see a series of bolts holding on a plate on the innerside (machine side). This plate has to come off to get to the lining. By looking at the left housing and the tranny drive pulley you will realize this is not an easy tear down.
