wash on weekends, not driven after.
you could contact parts central on FB and he can quote you on a new genuine piece. Maybe the price is close to what you would get used. Part no. 74141-TM0-T00
always maintained from 3s until i took over. Most of the things are wear items like shocks, rubber components,etc. Bad luck I guess on the brake cylinder.
About the ac, well as far as I can guess a very slow leak started 2-3 years prior (later to be found it was a bad o-ring). But 3s are fixated with the evap sensor going bad on this model, which causes ice buildup. To them a slow leak wasnt possible. Thus moisture getting into the system over the last couple of years, that could have led to the evap corroding. Currently the ac is working great, on original compressor.
