Steps to replacing rear brake pads


A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

How to reset brake caliper


The pistons in all calipers I have seen can be forced back into their seat to allow new brake pads to clear. If constructed as most, a C-clamp can be used to press the cylinder back in.

How do i change both front and rear brake pads on a 2004 mazda rx8?


CHANGING FRONT BRAKE PADS
Jack up the car. Take off your tire. Find the bolt on the back of the caliper and take it off. This should release the caliper, pull the caliper off the disc. Now you should be able to take the pad out. Replace the pad. You'll need a special tool to reset the caliper. As the brakes wear down, the caliper gets tighter so the brakes still work. I'm not sure exactly what its called, but you can borrow one from auto zone. Follow the instructions that come with it to reset the caliper. Slide the caliper back over the disc. If it doesn't go on, you need to reset the caliper more. Put the relese bolt back in. Put your tire back on.Drive slowly and test the brakes.
CHANGING THE REAR BRAKE PADS
The rear brakes on the rx8 are a bit different than most setups...be careful! The only way to move the piston back into the caliper is by way of a special allen head bolt that is directly behind the piston, on the back side of the caliper, installed under a 14mm bolt.
You have to remove this bolt to gain access to the allen head. As you loosen the allen head bolt(counter-clockwise), the piston will move back into the caliper.
Installation is pretty typical, again, the allen head bolt being the unusual part. The manual says to tighten this bolt until the pads contact the rotor, then loosen the bolt 1/3rd of a turn, then reinstall the 14mm bolt.
