I have an 01 Magnum 325 and whenever I set the break and leave it sitting for a while, the break stops working and you can easily push it around. I think the resevoir is probably leaking. Can anybody confirm this or give me new ideas and help me to stop this problem? Thanks for the help.

 

if it was leaking brake fluid you could see it some where and the res. would be getting low. i would think if you are leaving the brakes locked on for long periods of time that the master cyclinder will eventally wear out from the pressure put on the light rubbers in side the m/cycl. not really designed for hard long period of brake pressure like w/ the brake lock.
