Need pics or step by step instruction on rebuilding a rear brake caliper on a 98 park ave

The correct size socket or wrench. I use a c clamp and the old break pad to push the calipers down and grease the caliper to prevent squeaking. Hope that helps

1 Park your Buick on a level surface and shift the transmission to Neutral.

2 Open the hood and draw enough brake fluid from the master cylinder reservoir to bring the level down midway between the Full and Add marks if necessary. Use a new or clean turkey baster and a proper container. Then replace the reservoir cap but do not tighten.

• 3 Loosen the wheel lug nuts on both front tires using a lug wrench.
  

• 4 Raise the front of your vehicle using a floor jack and support it on jack stands.
• 5 Secure the rear wheels with chocks.
• 6 Finish removing the front wheel/tire assemblies.
• 7 Reinstall two wheel lug nuts, hand tight, on the hub assembly you will be working on first. This will prevent the rotor from sliding off the hub.
• 8 Force the brake caliper piston partially into its bore using a large C-clamp, just enough to allow it to clear the rotor when removing the caliper.
• 9 Unscrew and remove the lower caliper pin bolt using a Torx bit socket and ratchet.
• 10 Rotate the brake caliper upwards and secure it to the coil spring with a piece of wire.
• 11 Remove the inner brake pad from the brake caliper bracket and place it against the caliper piston.
• 12 Seat the caliper piston into its bore with the large C-clamp by pushing the inner pad with the clamp screw. Then remove the inner pad from the caliper.
• 13 Remove the outer brake pad and brake pad retainers from the brake caliper bracket.

Installing the Brake Pads

• 14 Clean the brake assembly of brake dust using brake parts cleaner spray and a clean, lint-free cloth or towel.
• 15 Install the brake pad retainers on the caliper bracket.
• 16 Inspect the boot around the caliper piston and make sure it is laying flat. If necessary, use a blunt plastic stick or suitable tool to set the inner edge of the boot flat while avoiding damage to the boot.
• 17 Set the new brake pads on the brake caliper bracket.
• 18 Untie the brake caliper and rotate it back into position over the brake pads and bracket.
• 19 Start the caliper lower-pin bolt by hand. Then tighten it with the Torx bit socket and ratchet.
• 20 Climb in behind the steering wheel and depress the brake pedal only about 2/3 of its normal travel distance. Release the pedal and wait for about 15 seconds before depressing the pedal again. Repeat this procedure until you feel a firm brake pedal.
• 21 Remove the two wheel lug nuts from the brake assembly.
• 22 Replace the brake pads on the other front wheel starting with Step 7, from the previous section, through Step 8 of this section.
• 23 Reinstall the wheel/tire assemblies.
• 24 Lower the vehicle and remove the chocks.
• 25 Add new brake fluid to the master cylinder reservoir to bring the level up to the Full mark if necessary. Then tighten the cap.

Your Buick has front disc brakes...and rear drum brakes...the usual concern is the front pads as they are used more...these are the easiest pads to replace...as you only need to remove the caliper from the rotor with 2 bolts to lift off...Be sure to push the piston all the way back into the caliper to install new pads...rotors are pop offs too...The rear drum is different...the brake shoes are held on with clips and springs...try keeping one of the shoe assemblies intact while you switch out the other shoes...be sure to inspect the rear wheel brake cylinders for possible leaking...usually an oil build up inside the brake drum...these are inexpensive and should be switched out on a 93 Buick...:) Hope this helps.

Okay, this is the step that says how to REMOVE the cable:

1. Remove retaining clip from the parking brake rear cable at the disc brake caliper. Release the tension from the parking brake cable and disengage the cable end from the parking brake lever on the brake caliper.
   

And this is the step that says how to INSTALL the cable:

1. Connect the end of the parking brake cable to the parking brake lever on the disc brake caliper.
   

Hi,
Brake Pads are an important part of your Mazda6's braking system. They are the replaceable friction pads that pinch the brake disc or drum when the brakes are applied. You should replace the brake pads before they wear beyond a quarter inch or risk damaging your Mazda6's brake discs.

Instructions
Remove the old Brake Pads

1. Step 1 Park your car on a level surface. If you have a stick shift car, make sure the car is in gear. Do not set the parking brake. Place blocks in front of the front tires so the car does not move while you are working on it.
   
2. Step 2 Open the hood of your car. Locate the master cylinder and brake fluid container. If necessary, remove brake fluid until the level in the container is less than half full. A turkey baster is a good tool for this. Put the brake fluid in the plastic container and dispose of it the way you dispose of motor oil.
   
3. Step 3 Raise the rear end of your car with your car jack. Remove the rear tire or wheel assembly.
   
4. Step 4 Disconnect the parking brake cable from the brake caliper. The cable is usually held in place with a retaining clip. You can use pliers to remove the clip and disconnect the cable.
   
5. Step 5 Remove the upper caliper bolt. Rotate the caliper downward until you can comfortably work on it. Remove the springs, pads and shims from the caliper.
   


Install the new Brake Pads
6. Step 1 Use the recommended tool to press the caliper piston back into the piston assembly.
   
7. Step 2 Insert the shims, springs and new pads into the caliper. Reconnect the parking brake cable.
   
8. Step 3 Rotate the caliper upward and back into place. Use the socket wrench to tighten the upper mounting bolt to 27 to 36 foot lb. (37 to 49 Nm) if you have a Mazda6 or to 16 to 23 foot lb. (21 to 31 Nm) if you have a Mazdaspeed6.
   
9. Step 4 Replace the tire wheel assembly. Lower the car to the ground.
   
10. Step 5 Add fluid to the master cylinder container to replace any you removed before you removed the old brake pads.
    
11. Step 6 Season the brake pads by making only gentle stops when you are driving for the first week after you install the new brake pads. Try not to do any hard stopping when you are seasoning the brakes.
    

Take care

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 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
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
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
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
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
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
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
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
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.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

you have to back off the adjustment nut on cable if its auto adjust pull up on parking brake pedal to release then just use channel locks to hook back up to caliper

there are two pins you have to knock out with a screwdriver and a hammer. make sure you place the screwdriver on the metal part not the rubber in the middle of the pin copy and paste this:http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?displayName=Brake+Caliper+-+Front&currentPage=1&categoryDisplayName=Brakes+%26+Traction+Control&navValue=14400852&itemId=prod61063&parentId=cat30058

you need to turn the pistons in with a special brake tool, you should be able to rent it from autozone.
