See related link, nothing special about the rotor when you get to that part of the brake job, just slide the old ones off and slide the new ones on (see detailed description of brake job with pictures in link). This is a very easy job to do yourself.

03 camry 4 cylider has a timing chain a 03 v6 camry hmilesas a belt and you change it every 90,000
2004 Toyota Sequoia has a timing CHAIN, not belt, so I would assume that an '03 also has a chain.
I normally change them when I replace my plugs. heres a informative link that could help you out too. http://www.autotap.com/sparkplugs/ppc_spark_plugs_replace.html Toyota echos do not have spark plug wires they have coils which do not need to be replaced unless they have broke one of the nice things about echos
To fix the trunk release lever in a 2003 Toyota Echo, first, check the lever's connection to the cable and ensure it isn't disconnected or damaged. If the cable is intact, inspect the lever itself for any signs of wear or breakage. If necessary, replace the lever or cable by removing the trim panel in the trunk area for access. Reassemble everything and test the lever to ensure it functions properly.
