How can I?

Stop the inside pads on the front brakes from wearing more than the outers.

Ive looked at the current pads and 80% left on on outer compared to nearly nothing on the inner.

Plan on replacing tomorrow.
 
replace the pins clean the caliper including scraping the crud from where the pad slides , ensure all pistons are pushing out evenly by getting a friend to push brak pedal gently when no pads in ( you watch pistons ) ensure they push back ok , new pads copper grease ( very little ) the bottom where the pad moves and all will be rosy again
