I was on the Sidewinders desert run in Lake Havasu last weekend and I couldn't release the line lock. I thought I was screwed cause it took about ten tries to get it to release the brakes. Called Summit today & ordered a solenoid type line lock.

I had this happen on my Jamar I think I pushed too hard on the pedal.. I cracked the output fitting and it broke loose. I haven't had any issues since I stopped stomping the shiat out of the pedal.

adding a few keywords...this fixed my problem but took forever to find.

just installed Jamar Line Lock , stuck, will not release, how to unlock, pressure, problem
