I have an 1986 5000TQ for which I recently replaced the brake pressure accumulator. I was hoping it would solve two problems: 1. Brake pressure goes hard after 4-5 pumps after stopping engine. 2. Pentosin being pressured through top of reservoir The first problem was solved - but I'm still losing fluid through the top. Any BTDT's, or ideas? Thanks in advance, john.remington@pipe.nova.ca
