Re: how to replace rear brake pads
Jack up car, remove wheel. There are two bolts that hold the caliper on. Remove these. Caliper comes off, take old pads out. There is a special tool to compress the piston back into the caliper (do not use a C Clamp on the rears.) Put new pads back on, re-install the caliper, and put the wheel back on. Pump the brake pedal until it is firm. Done.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

I just had this problem myself. I ended up removing the caliper completely and drained it of all of it's fluid. I then held it in my hand and used an 2" round bar to beat the piston back down. once you break it loose it goes fairly easy. then bolt it all back up and bleed the brakes
For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow: 1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose! 2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper. 3. Now you must thoroughly clean the brake calipers (free of grease). 4. Remove outer brake pad from brake carrier. 5. Pull inner brake pad out of brake caliper piston. 6. Check up the brake fluid level on the reservor, and emptying if neccessary! 7. Push piston back into brake caliper housing. 8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward). 9. Install outer brake pad into brake carrier. 10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 11. Install both caps. 12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!!
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.
Loosen the brake fluid reservoir cap to allow pressure to escape. Use a large C clamp connecting it to the front of the piston and back of the housing. Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads.
What aboout the brakes do you need replacing? Just the pads or pads and rotors? I will help you work this out just let me know if you get stuck. Picture manuals are only as good as the mechanic taking the picture, i however need no manual to assist you.
Just observe how you take the old ones off. Pads can only snap in one way. It may take some effort but clean the caliper of rust you shouldn't have any problem. Remember to crack open your brake fluid reservoir before compressing the caliper!
