brakes after washing
After washing the jeep or going through the wash, my front brakes get wet.. obviously... BUT they remain wet for up to 3 days, even with excessive driving. Most people say theyre brakes dry up after a few stops...
My braking ability plummets and they make an aweful grinding type of noise...
Why? Do I need new rotors?

They should be one of the most important parts you like the stop right? Front brakes are the easiest to replace clean fix and control about 70% if not more of your stopping power due to forward momentum and weight. You'll be looking for any dark blue spots, fine almost scratches along the rotor, and grooves from metal to metal contact. Before you washed anything wrong before? Or any repairs made?

Also to see if there is friction material left on the brake pads or if they are worn down to the metal backing plates, or if the water is washing some sort of contaminant on to them. Do your axle seals leak by chance?

might be a leaky seal on the piston inside the caliper which would allow brake fluid to get washed onto the pads/rotor? That would probably take longer to burn off than just water. How's the fluid level been in the reservoir?
Once you get the wheels off, there's only two bolts holding the calipers on; so it's real easy to take it apart and get a good look. When putting the calipers back on though, be careful not to strip the caliper mounting bolts which thread into the steering knuckle. They only need like 15ft-lbs of torque or something really low like that. One was stripped on my old XJ when I got it, and it wasn't fun fixing that one. Grease the 2 mounting bolts & sleeves (which the calipers slide on) while you have them out too, they like to dry out and stick.

Since u don't know anything about brakes I take it you don't know what kind of pads you have. If you have ceramic pads that could be the problem. If you have less than 4mm of pad life left I suggest replacing pads and rotors

Okay so I'm pulling off the wheel, looking at the rotor for marks. And blue marks.
Then I take the 2 screws off and the pad slides off? I could use some detailed instructions so I don't **** up my brakes. Assembly and re assembly. Thanks guys.
Measure the pad by thickness, and feel it to figure out what material? What different types of pads are there
