[QUOTE="thoughtbelt923, post: 130719, member: 23095"] This is very likely an excessive leak issue from one or both of your drive motors. Likely your left considering the stick is harder. It may not be getting enough pressure to unlock your brake. Before you unlock the hydraulics, your brakes are engaged. It requires pressure to unlock them. When you unlock them, a valve releases pressure to the drives to release the brakes. If the seals are bad in the motor, they won't fully release. They also leak back to the case drain which causes your low pressure. I wouldn't drive it too much or you risk trying to push through the brake and damaging the rest of the hydro system. Look up a case drain flow test. Essentially removing one drive motor line from your case drain filter, putting it in a bucket, running the bobcat with hydraulics engaged then disengaged. Then do the other side. Compare the flow rate. I bet your left side will be pouring when it should be a less than 50 psi drip or stream. You'll need to get a new drive motor or have it rebuilt if that's the case. [/QUOTE]
