Whats up with the 400ex front master cylinder cap screws stripping out so easily?

Yeah, they all do that, not just the 400EX. I always make sure I use a screwdriver that fits the head of the screw real tight and put it on the head of the screw and tap it with a hammer to jar it. That usually makes them come loose a little easier, but sometimes not. There is a lot of difference from one phillips screwdriver to another, make sure you find one that fits real tight or you've lost the battle before starting. Those little assorted bit sets that come with some tool sets are usually best for that.

If it's too late and you already stripped them, use a dremel to cut a slot in the head of the screws and use a flat screwdriver to remove them.

Ive already got them out but I would almost rather pay $2 for a itty bit screw that is stainless steel!!!!! I'm sure if I went to the hardware store, I could find a stainless steel screw to fit it.

If you really wanted to, you could get bolts with hex shaped heads, that way you could use a wrench or socket to put them in and remove them when needed.

i've had to remove sooooooo many of those screws..it wasn't a pretty sight..lol..they all rust really bad inside the housing...like helmut said..tap it with a hammer before you try to back them out..i've had to use a sharp chisel and hammer to work them out on alot of bikes i've worked on..they are a pain..thats for sure.

Just use a little anti-seize and call it a day. Use caution when using stainless screws in aluminum holes. The dissimilar metals will accelerate corrosion (called galvanic corrosion) of the threads on your master cylinder. The harsher the environment (the more moisture your bike sees), the faster it will corrode.
