any chance during this rain you were doing any burnouts, wheel peeling etc. if you take off and keep spinning your wheels FAST in the rain it will trip a sensor that will go away on its own

^^^ i agree. if it's doing it only in the rain then start checking connections. especially any connection affected by tire splash. pull 'em apart and look for the greenies. clean 'em up and put a dab of dielectric grease.

how'd the interview go?????

intresting...... master cylinder was bone dry... i followed all the brake lines.. no leaks. followed the hydroboost lines. no leaks.. no leaks on calipers or cylinders..wtf only thing i can think of is powersteering/vac pump leak.. powersteering ran low so it sucked it from m/c?

i didn't see that part. guess the flashing lights caught my eye.

you can't see any fluid leaks mobs? do the hydroboost master cylinders have a seal in back of them to hold fluid in? mine has vacuum booster so i don't know. but... the rear seal on my master started leaking and all the brake fluid was going into the booster. maybe you have the same problem.

did u pull ur rear wheels and look at the wheel cylinders?

no i didnt pull the wheels normally if you have a substancial leak, itll drip down on the inside of the tire from the bottom of the drum., i cannot see any leaks.. i followed all brake lines and such.

true. how often do you check ur brake fluid? maybe it's been leaking a bit longer than you think.

back of the master cylinder is the only thing i can think of then. like i said, i've seen the regular vacuum boosted master cylinders leak there.
