It looks like a hydraulic clamp. When hydraulic pressure is applied with the brake pedal, the caliper clamps the disc brake pads to the disc brake rotor to stop rotation.
Any reputable auto repair shop should be able to repair your brake calipers. If you are handy, you may also want to look into a caliper repair kit (readily available online and at stores like Sears) and do the work yourself.
FRONT BRAKE PAD REPLACEMENT Jack up vehicle and remove the wheel. before removing the caliper , be sure to depress the piston into the bottom of its bore in the caliper with a large C- clamp to make room for the new pads. look behind the caliper and you should see two bolts holding the caliper on. remove the bolts, "DO NOT REMOVE THE BRAKE LINE", the caliper should pull free from the caliper mounting braket. DO NOT LET THE CALIPER HANG BY THE BRAKE HOSE". Separate the brake pads from the caliper mounting bracket." Remove the steel slippers from the upper and lower parts of the caliper mounting bracket. After doing the above You should be done with removal to install follow the above steps in reverse. The rear brakes are the same as the front brakes to replace. However the rear brake disc is also a disc / drum that houses the parking brake pads. The parking brake pads are behind the brake disc. you will have to pull the disc off to get to these brake pads. The removal of the parking brake pads requires more time and is a bit more difficult to replace. I would inspect the parking brake pads before removal and replace them only if needed.
there suppose to look like a dick
Check brake fluid to make sure it has not gone dry, if so then will require a total bleed brake system. Have the brakes been replaced recently? Could have a piston in the caliper stuck, which will then require to pull that caliper and replace it but then look at doing both.
Look with a flashlight between your rims at the caliper and you will see how much brake pad you have and most places will do a free brake check, 2/32 is when they should be replaced
You need a rear disc brake caliper tool set for this job. A pair of needle nose pliers can work also, but damage to the caliper is likely, if you're trying to get it done in a hurry.These rear calipers cannot be compressed with a clamp like the front calipers can be.The piston actually screws into the caliper. Again, look for a disc brake caliper tool set. Harbor Freight Tools sells a $20 kit that will do the job.
Loosen the lug nuts on the tire. Then jack up your car. Remove the tire. You will see the rotor, pads and caliper. Unbolt the caliper and set out of way but do not let it dangle by the brake line or crimp it. Look at the rotor to make sure it has no grooves in it. If it does it may need to be resurfaced at a shop. Turn the caliper over and see the pins or bolts holding the brake pad. Loosen them to get the old brake pads out. Replace and then put everything back together.
If you can see the brake caliper and rotor, then it has disc brakes. If all you see is a large drum then it has shoes. If you can see the front brakes thru the wheels, you can identify disc brakes. If the rear look like the front, then they are also disc brakes. However if the rear look much different, then chances are they are drum.
Check for loose or missing bolts. Check also for incorrect wheel rim, incorrect rotor, or incorrect caliper. year of car/truck ? if its a dodge truck look at brake caliper adapter for wear,check caliper retaining clips if their broken they will let the caliper move up in the caliper adapter hitting tour wheel hub . is the wheel right one for veh ? If you just changed the pads and did not compress the caliper piston all the way down. the caliper can rub against the wheel. The whole caliper floats and if the piston is not fully compressed it can hit the wheel with the new pads on.
It looks like the word BRAKE. It is pronounced as BRAKE also.
first take off the wheel then look at the caliper bolts they can range from metric sockets to torx sockets remove the caliper secure the caliper so that it does not hang from the brake hose then inspect the caliper support bracket bolts remove the two bolts being careful not to get hurt when it falls to the ground using some penetrating fluid and a hammer tap the rotor from the backside tap the rotor off of the hub
