Hit it with a sledge hammer
The rear disc break pistons on Mazda are not to be pushed in. Instead you turn them in clockwise.
Better hope it is not a drum brake- it was originally equipped with a disc brake caliper.
it either has front disc brakes and rear drum or it has front and rear disc bakes. look for a flat disc in the front and back - those are front and rear disc brakes-they take pads. The drum brakes take shoes.
Need to know if the vehicle has rear disc brakes or drum brakes and which part of the e-brake system you want to remove, front cable, rear cables, e-brake linings, etc.
this is a bit tricky because the e brake are shoes that fit inside the disc. you will see an access hole usually with a rubber plug, that hole has to be at the 12 o'clock position, then you have to loosen a cam that will allow the shoes to collapse inward, then you can remove the disc.
Rear disc brake pads, no. Rear brake shoes, yes.
Rear is to the back of the vehicle. Brake rotor is the rotating part of a disc brake.
there are brake shoes in the discs too . just remove the discs and you will see them. they are applied by a cable.
Rear disc ? if it is rear disc brakes there is a drum brake in side of the rear rotor that is your parking brake and has an adjuster in it if you pull the rotor off.
If the truck has disc brakes on the rear then the park brake shoes are located inside the rear rotors. You have to remove the brake calipers, pads and rotors to access them
You will need a lot wrench to remove the tire. You will need a needle nosed pliers and screwdriver to remove the brake pads.
Lift the car on the car jack, remove the tire, remove the brake shoe/caliper, remove the brake pad. Put in the new brake pad, replace the brake shoe/caliper, put the tire back on the car, and lower the car to the ground.
