I just started the car after a winters storage and am now encountering a strange issue with my vacuum brakes. I recently changed all my vacuum hoses to hard lines with push locks and now when I pump my brakes they go from normal to very hard after three pumps or so. You can actually see the vacuum lessening to almost zero on the boost gauge when I do this.
Do you think it may be a check valve issue?
If so, does someone have a part number of a good check valve.
