Cooper rear caliper pistons MUST be rotated as they are pushed in. It is due to the parking brake being integrated into the caliper.

Did you notice the brake fluid level in the master cylinder before you tried to collapse the calipers? You should see a rise in level as you collapse them (however far they did collapse). If you're not seeing any change in the level (it should fill up) you might have a plugged valve between the caliper and the master cylinder. Loosen the brake fluid line to the caliper and try collapsing it again. If still no go, start dismantling the caliper and look for bent, broken, stuck or mal-adjusted pieces.

I noticed little smoke coming from the right passenger side wheel after using breaks. I lifted the the car and took off the wheel but it feels a bit tight to rotate the disc.


Front or rear?
The Sounds like the caliper might be sticking. Is the wheel getting hot?
The rear brake has the emergency brake incorporated in it.
You need a special tool to retract the caliper it spins it back in while it presses.
Take the caliper off and clean and lube the guide pins with a grease for brake parts like Permatex 24115 Ultra Disk Brake Caliper Lube High-Temp Silicone. If rusted, replace the parts.
Make sure all the rubber protectors are in good shape if not replace them. They keep moisture from rusting the brake parts. If the caliper is frozen, just buy a new assembly and install it. Here a video that should help!

How to change rear brakes on a 1997 mercury sable


Replace caliper with old brake pads put 1 bolt in place to hold together while taking a large screwdriver and prying caliper piston so that it compresses piston & block wedge to rear of bracket it should make enough room to install on new brake pads, the other way is to use a large c clamp put 1/4 pice of wood in between c clamp and caliper so you don't damage or Mar the caliper also check YouTube.

Just replaced my brakes pads and rotors, i tried my e-brake and the ABS and brake warning lights came on and E-brake didnt work. Do I have to adjust the E-brakes?


Yes, when you replaced pads on the rear brakes you need to readjust the rear brakes. This is usually very simple to do. Find a safe area to back up about 50 ft. You want to start the vehicle backing up then hit the brakes hard to activate the automatic adjusters until the E brake works. Do this about 3 times then try the Emergency brake and see if it holds. If it doesn't repeat the process. The ABS warning probably came on because a rear caliper extended too far so check those and make sure the boots on the ends of the calipers did not come off. If they did, collapse the caliper and replace the boot. In some cases with older vehicles you can actually adjust this manually with a flat screwdriver from the back side of the drum. To do that you want to adjust it until the rear pads make full contact with the drums then back it off 3 to 5 clicks. so the pads clear the drum in normal operation but are close enough to work when you apply the brakes.

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.

REAR BRAKE REPLACEMENT


ase mechanic:

those calipers in the rear have slots on the piston right. that means you have to turn the pistons in clockwise. sometimes a pair of needle nose pliers put in the slots and turn will work, otherwise there is a rear caliper brake tool to turn those pistons in.

Back brakes


rear brake are just pads. but you will need a piston pusher. go to your local auto store and get a universal piston pusher. should look like a four sided block with peggs sticking out. make sure the e-brake is off, remove the rear wheels, remove the calipers and replace the pads push the pistons in with the universal pusher and reinstall the caliper.
