Can't advise price for E-brake shoes. Perhaps they require adjustment? The backup light switch is the problem on the lights. Easy job. Switch screws in to the top of the trans case, just under the edge of the air filter box. Has a two wire conector, use a 22mm deep socket. The trunk light is probably turned off. There is a thumbwheel switch on the lamp. 1 position is always off, other is on when open. The ground signal comes from a micro-switch in the latch assembly.
