The " Service Brake Booster " light has come on the dash. I can hear the booster cycle through when I start the truck, then the light turns on. I hate to replace the booster if I can hear it running and working. the master cylinder and brakes work fine, a little more spongy without the help of the booster. is there a fix for this? possibly a o-ring I need to check? Do the boosters go bad? Please include pictures and descriptions if possible. Thank you in advance for any help on solving this issue.
