Brakes Locking Up When Wet
I have a 92 f150 2wd 300 i6. i have a question regarding my brakes. Hope this is the right forum. It seems that if its raining or has rained when I go to drive my truck the brakes are real touchy right away. Just have to touch the pedal and the brakes lock up. I just replaced rotors and pads on the front. They were pretty bad.
I am not sure if this is common or if I have a problem I can fix.

I have experienced the same problem, but I can't remember it happening recently though...... I have a '93 F150 I6 4x4 with rear ABS and every so often (doesn't even have to be that wet out) my rear brakes would lock at the very slightest touch initially and then operate properly. It even happened in the snow once, and NO it wasn't just loss of traction! Can't say that I remember this happening since I changed the rear pads.

Ewellman, I have basicly the same truck (except it's 4x4) and when it rains or if I park my truck for awhile while it's raining and then go to drive it later, my brakes do the same thing. I think it's normal. Its just the water making your brakes grab, I wouldn't worry about it. As far as I know, it's normal. All of the vehicles I've ever owned did the same thing. Hope this helps.

There was some kind of fix for that for trucks sold in Alaska because the water would freeze the front pads to the rotor. All you should have to do is touch the pedal once and the lockup should go away for the front rotors.

I get it all the time when I first drive my 97 F-150 after it has been raining or really humid. The rear brakes are really touchy and if I don't think about it they lock at the first stop sign I come to. After that they are fine.
It can be a little embarassing if there is some one standing right there when you come up tothe sign and then EEEERCH it looks like you slammed on the brakes.

When thr rotors get hot and fluid comes into contact with them ( moisture) the fluid evaporates. When the fluid evaporates it leaves a film (deposits) on the face of the rotors. These deposits cause the pads to grab. Drive your truck and take it home and spray the rotors with water. You 'll see the water evaporate and leave deposits.

My dad had the same problem with his 95 F150 4x4... The fix at the time was the break pads (none metalic). When I would drive it back then I would drive about 50 yards with the gas and the break on and it would solve it (quick fix). Now on his (2002 4x4) and mine (2003 4x4 STX) we don't have that problem anymore!!!

The problem is one of two #1 axle seal leaking fluid on rear shoes #2 most common problem is rear shoes not adjusted up right,they should have good drag on them,if not they will grab.

replace your rear shoes....ford has had this problem on their trucks for a while. I put on a set of autozone shoes on the rear and it cured it. I figured cheap shoes till i get my three quarter ton axle in the rear
