I have a 1995 Discovery and need to know how to change the rear brakes. Any suggestions.

 

See if this page from the RAVE shop manual (all free at links below) helps guide you to pad-slap that primo possum smasher. I'd block the front wheels carefully.

 

Buy the brake pads of your choice.
Buy a new brake hardware kit.
Remove the wheels.
Remove brake hardware.
Using a pry bar with old pads in place pry the calipers open.
Remove old brake pads.
Install new brake pads.
Install new brake hardware.
Put wheels back on.
Done.
No need to remove the calipers unless you are doing rotors too, then that is a whole other story.
