my cars been parked up for a little while and just started it up and drove it down the road.

basiclly when i pressed the brake pedal the pedal just feel soft and stays down and don't feel like its very bouncy so it springs back after being pushed down.

any idea.? i know the little yellow cap that push's down anc click fits on the resevoir is missing. Not the screw cap the little pop on yellow cap on top of the screw cap.

hope u can help

cheers
