Hello Ron,


 


Is the OBD tool necessary? I have no access to the tool.

Expert:  Ron replied 1 year ago.
Ruben I have had fairly good success doing the pads and rotor with out the scan tool. Just be sure to do one side at a time.
Customer: replied 1 year ago.

On more thing Ron. The pictures you supplied have changed, they were useful. Is that some glitch on the site?

Expert:  Ron replied 1 year ago.
Sorry about that Ruben, there must be a site issue, try them again and this time try and print them out for reference.
