2001 Standard striped front master
brake cylinder screws.
I tried using a screw extractor I seem to have made matters worse.
I need advice.

When you get those out, buy a JIS screwdriver so that doesn't happen again.

What kind of extractor? The backwards drill type, or the drill a hole and then use it type?

You could have luck with a Dremel type tool and a cutoff wheel to make a slot, so you can try a flat-blade screwdriver, but first, use a small hammer and tap on them to shock the threads.

Next time, find a set of JIS type screwdrivers, as Phillip's don't fit well. Result: stripped out heads.

You speaking of the cover screws or the mounting clamp screws? Sounds like a sitting too long issue. I haven't used a easy out in years because of their limited use. Work better on larger applications but smaller screws, there's a very limited technique using them. I use a small round center punch/chisel made from somewhat tougher steel and a 4 oz. ball peen to catch the bolt end and plenty of WD40/Brake Free. Take your time and work it back and forth. Left hand drills are also an option from time to time.

As for the JIT screw drivers I have a pair of Vessel brand. I use the #2 a lot on just about every screw in the world. Nice grips also.

JIS is pretty much no more.  I have newer Harbor Freight phillips to the new std,
they work great on JIS screws.



""Most JIS advertised screwdrivers sold today by companies like Vessel, Hozan, and others are actually conforming to a new standard: DIN 5260 which is identical (at the tip) to the newer ISO 8764-1.
To date, I have only been able to find one confirmed manufacturer that still uses and builds to JIS B 4633, and that is SUNFLAG otherwise known as New Turtle in Japan:

The reason these companies have changed to DIN 5260/ISO 8764-1 is because the new standard is designed to work in both Phillips and JIS screws. For the most part that is true, it does work on both screw types, but like anything meant to work with multiple things, the middle ground means compromise. The JIS standard screwdriver will always outperform a DIN/ISO screw driver in the worst of conditions on a JIS screw, and the same is true in reverse.""

Without pictures it’s hard to say. But if you’ve buggered them up as bad as you say. Just drill the head off   Once you remove the cover there should be enough of a nub to grab with a vice grip. Or, take it to a qualified mechanic

We did get them  out yesterday  using a drill to make a little deeper hole and then an appropriate Torx and gave them a little tap, small ratchet. Thanks.    I wont let this happen again. I replaced the screws
with a touch of antisieze compound.

I’ve had the same problem in the past. I’ve always replaced mine with a stainless steel Allen head screw. Never a problem with them.

I replaced mine with SS screws when 1st. got the bike. If you use regular steel screws in any aluminum always use anti seize on threads but SS gets it also regardless especially in exposed more to road crud etc. applications. I buffed the SS heads for a better shine.
Now as for phillips head fits, I size the bit/driver before using as I have plenty of offerings so to speak.
