Hi all, Took the 280z out for first time this year at the weekend. Noticed the brake booster making a strange sound along with pretty poor pedal feel (spongy and felt weak). I rebled the brakes but still felt soft and obviously sound from booster didn't stop. Does this sound like I need a new booster? Also can you confirm it is the standard 280z booster and any idea which master cylinder is fitted? Thanks!
