I recently checked the rear drum brake shoe of my mazda protege 2000 (ES) and it looks like its having un even wear pattern. The Leading Shoe is Ok at the top but completey worn out at the bottom, While trailing shoe shows looks ok and has uniform wear. I heard that self adjusting screw may not be working propery (not lubricated properly), but i doubt that protege has any such screw. I am planning to replace the brake shoe myself this weekend, but slightly affraid as i am not sure what causing this uneven brake wear. It may happen in new brake shoe also. I think i need to apply some grease to some parts, but not sure what those are?

I have Mazda Protege manual and it doesn't talks about adjuster screw. If you can give me your mail id, i will send you a screen shot of the part description and layout diagram from the technical manual as well as the pictures of my brake system which i took just 2 days back while doing a routine checkup.

Some uneven brake shoe wear is common and normal with non-servo brakes. As far as what you need to grease, use anti-seize on the backing plates where the shoes contact (there will be 3 or 4 flat spots on the backing plate per shoe) Also, your car does have an adjuster screw (assuming all the parts are present) look for a cylinder that extends between the shoes, with a star wheel on it. Unscrew the star wheel and anti-seize the threads, and the cap on the other end where it need to spin. This will make it easier to adjust. Once you are done installing the new shoes, stick the drums on and adjust the brakes to have slight and even (side to side) drag. Double check the adjustment by pulling the e-brake, spec is 5-7 clicks. Also, I advise doing one side at a time, so you have a reference as to how it should look. Don't mix up parts side to side. Also, you should turn the drums. Most parts stores can do this for a nominal fee.

Some brake shoes, beacause of their quality maybe too hard and are cutting away at your drums therefore causing uneven wear also hand brake adjustment may be not equal. check amount of wear and if it looks too bad replace drums because they will shorten the life of your new shoes.

The caliper is caught. those brakes have a million piston which pushes against the rotor and the whole caliper physique can circulate extremely so as that the rigidity on the two factors is even. The caliper can not circulate so hence, the piston factor pad is doing almost all the artwork and is donning away lots speedier.

The brake drums may be worn down.
Consider replacing them as well.
