I thinik you have to pull the lever and release it several times to get it to adjust initially. I doesn't have an adjuster like most american made cars have. The emergency brake lever adjusts it every time set it.
I think the manual says something about engaging the brakes hard. slam them on several times.. (I may be wrong the FSM
is at home) The adjuster on the rear brakes is a small cam
with a spring on it on the arm assembly. If not absolutly
free of crud they tend not to adjust up. Better than the old
9" drums on my Jeeps though. You had to adjust them everyother week..
I just did this yesterday. It is very very very very simple. Just step on the brake, release, and you're done. Granted if the adjusters are rusted to nothing or are in very bad shape or the brakes are wrong or worn down to the steel, you'll run into problems... Spend the 16 dollars (9 for all 4 shoes and 7 for the "brake hardware kit" (MUST GET THAT!!)) and replace the brakes..
I had no idea what a "brake hardware kit" was. I was asking an auto guy @ church about some problems with the rear brakes on the zook. He suggested replacing the rear drum brake shoes and installing a new "brake hardware kit". I went to the parts store, got the shoes (10 dollars after a 5~10 dollar core charge) and asked specificaly for a "brake hardware kit". The kit comes with the springs for the e-brake return, the lower brake pad hold-em-down spring, the main brake return spring, what seems to be a smaller aux. brake return spring, and the little clippy things that hold the brake shoes to the backplate. Very very very cost effective. I had a bad cylinder (brake hydraulic cylinder thing) and had to replace it. It was about 20 dollars and no core. 1 can of brake parts cleaner went allll the way with both sides. They suggested I use a "brake hardware kit" each time I change the brakes for safetys sake. It is very cheep too..
