the above 2 answers are right. But you also need to apply grease to the shaft of the 2 bolts. It fits in a rubber boot.|||the simplest solution to your problem is to go to a mechanic.if you%26#039;d like to change them yourself,it all depends of what type of brakes do you have installed on your car.
if you have a simple type you have to remove the wheels and disengage the hydraulic sistem.after that you remove the braking plates(2 pieces/wheel)and take out the braking system.
that is as simple as i could describe|||It%26#039;s not hard really. Just watch out for my spelling. If your car uses DISK PADS and not BRAKE SHOES it is easy. All you need are the appropriate spanners. I don%26#039;t remember the sizes, but if you have from 14 up, you should be ok. Remove the tyre/rim. Find the brake calliper. There should be 2 bolts on the calliper, one longer than the other (you%26#039;ll know when you take it off). Remove one, or both if you%26#039;re more comfortable working with the calliper off. Remove the disk pads. You may need to pry the calliper down, as in the current position, when you place the new disk pads in it wont fit back onto your disk wheel. Place in the new disk wheels, and do the reverse of pulling it down. Make sure you put back the long bolt and short bolt in their appropriate spots. If your car is different from how I described it, I recommend not trying, unless you know you want to and can have a mechanic come and fix it if you make a mistake.|||on the front jack up the car and remove the rim now you should be able to see the rotor and calaper the calaper is what holds the brake pads on the back side of the calaper should be two bolts holding it on remove them and the calaper should slide off remove the old brake pads there is a pistion in the calaper that has to be colapsed so the new brakes will fit on the rotor some cars are different that others but this method usualy works for most cars take off the cover on the break fluid resovior first then take a big c clamp and a socket that will fit in the center of the calaper piston position the c clamp with the screw inside the piston and the other side on the back of the calaper be careful not to damage any break lines while cranking the c clamp turn the c clamp until the pistion is all the way inside the calaper now you are ready put the new brakes on put them in the calaper and slide the calaper back on the rotor bolt it back on put cover back on the resovior start the car and apply the breaks pump them until you feel them getting tight turn off the car check the fluid check the calapers and the break line for leaks if ok put the tire back on ps when colapsing the calaper pistion fluid may leak out of the resoviou this is normal but messy so you may want to put a pan under it to catch the overflow no need to bleed the brakes there should not be any air in the lines good luck
