Maybe this is just the way it is but when I get about 1 quart low I can uncover the pump when braking fairly hard, not skidding but more than normal. Also there is one of those round-abouts that going through that too quickly gives a left/right and uncovers the pump too. The pressure goes to zero for several seconds then comes back up. No problem when full. Are there some 235 pans better than others? I have a '61 235 but no telling what the pan came off of.
Thanks, Dennis
