Alright so it seams like any time i drive around in water or it rains really hard and my brakes get wet, they seam to work better. Why is this?

I get this too for some odd reason.

my rear wheels like to lock up when i hit the brakes and it raining.

I just noticed that today. I've got quite a bit of travel in my pedal, though it is firm when it finally gets to that point. Been battling a few annoying squeals in the front brakes and so forth over the past few weeks. Got the first good rain in quite a while this morning, and... pedal barely traveled, no squealing, firm braking. No idea.

Mine does too! I think its just washing all the dust out and they work right again lol that's my theory!

Disc brakes perform better in wet weather, because centrifugal force tends to fling water off the brake disc and keep it dry. I also read that early vehicles used what was called "wet" Brakes like in the 1920's they added oil of some sort to the brakes to get better stopping. and the squeal u hear may be the its almost time to change ur brakes sensor... Lol or plain old dust...

If you have alot of travel in my brake pedal, try bleeding them.

True. Brake fluid breaks down and becomes less effective after 5 years on average. So bleeding and flushing the system is a great start.

Mine does it too and I have a totally new brake system,from hard lines, pads, brake fluid,rotors and master cylinder, only thing I haven't replaced is the rubber lines yet and I'm saving up for extended lines to replace them with,

Gee oh Dee

If it flings the water off wouldnt it perform as though its dry?

And what brake sensor needs to be changed?

Mine preforms the same wet/dry. They'll lock up easier, but thats to be expected as grip is lost on wet surfaces.

Drums get "grabby" in the rain.

Because the the disc gets wet, and with the flinging of the water it makes it it work like a squeegee is best way to explain it I gues, and with the sensor Best way to describe that is I have heard it called a DUMMY squeal or DUMMY sensor, when my brakes get low I get a squeal on my JGC. And soon after that if not changed Im metal to metal. Let me look for where I read both of these and post for your enjoyment ;-)
