All the best, Bill '79SC.

BINGO What he say's.

Bob. air will only compress so much, slow depression to the floor indicates pressure is bleeding off somehow... assuming there is no leak I vote for the MC.

Slow depression.. as air gets more and more compressed the back pressure on the pedal will increase noticeably.
