Right well along the lines of sanj's haynes manual and general screw ups. Here's my latest guide to changing the rear brake discs. This was done on my Corolla but the brake system on most UK built toyota's is the same. Made by TRW with rear discs and a handbrake system in a drum inside the rear disc. Things you will need: 1. 21mm Socket for the wheels 2. 14mm socket for the carrier bolts 3. 12mm socket for the guide pin bolts 4. flat bladed screwdriver 5. a G Clamp 1. right the first thing to do
