Well Willy you might have to tell us some more about what is happening.

Did you remove the calper? You will have to.

Then the pads should come out easily. There might be some retainers of some sort.
I've done so may brake jobs that I really don't remember what system is on what truck. You'll have to refresh my memory

If you do remove the pads you'll need a c-clamp to push the piston back. A 4" c-clamp is probably big enough. (I've also used 2 small pry bars between the old pads).

Before you do the brake job try cracking the bleeders, just in case they break off.... theres no point in doing the job twice if you have to replace the calpers.

Do you know anyone that works on cars, even an auto shop teacher? Ask your best teacher if your school doesn't have a shop class.
If you do I sugest that you ask them to come over and assist you.
One of the worst things to make a mistake on in a car is on the brakes. You can't replace your sisters life or anyone elses.

And if you can't find anyone how about starting a new thread entitled
Can someone around (your city) assist me.

Good Luck, and let us know whats happening
