So I just finished putting my nice new SS front brake lines on and I'm going to take the master cylinder cover off to refill/bleed the brakes. I get the left screw out with no problems, the right side was more difficult so I noticed that it was a soft metal and that I should try to not strip it. Every way I know how to not strip a screw I tried but it still did it. Now that I'm livid I need some help as to how to remove that dead screw. Any takers?

impact driver might do the trick, if you dont have one, use a hammer and a good fitting screwdriver, tap the handle of the screwdriver, and everytime you hit it, apply pressure to the screwdriver(twisting action)

if this doesnt work, get a small flat bladed screwdiver, and put it on the outside edge of a groove in the head, and try and tap it round.

i replaced mine with round topped screws, not countersunk, so if it siezes again, all i need to do is cut the head off.

I had the same problem on my brake master and clutch too. I used an ez-out to get the old screws out, and replaced all with new stainless hex head screws. Just get the smallest ez-out you can find.

Thanks, you're my hero's. I thought about the EZ out thing because I've seen them but wasn't sure how well they work.

Sears sells some things call screwouts or something. They are bits that you put in either an impact driver or a reversible drill.Try the impact driver first.The bits are like lefthand drill bits that bite into the screwheads as you try to unscrew the fastener.If that fails if you are very careful you can drill the head off using a bit slightly larger than the threaded part of the screw.Just go deep enough to get the head to pop off then use some pliers to remove the rest of the screw from the mastercyl.If you try the screwout thing tap the head of the screw sort of hard with a flat punch before you attempt to remove it,The vibration will tend to reduce the friction between the head and the countersunk seat in the cap.

I've had good luck with left handed drill bits. Even when drilling a hole to use an Easy Out a left hander often will turn the screw out.

+1 for left-handed drill bits. I have also used EZ-Outs & the thing from Sears. I am very, very glad my '04 has a big, round screw top reservoir!

I replaced the cap screws on the Trident's MCs with stainless Allen heads. They're less prone to stripping than the Phillips heads & easier to drill out if they do. I put a tiny dab of anti-sieze on the vey bottom threads of each one. I had to buy a box of 100, PM me if you want 4 or 5 cheap.

Cheers,

Mine is the same. I was so depressed i was going to buy one off ebay. I went down the impact driver route, and horray it worked. I bought a new screw from the dealer before i hit it.

I don't own an impact driver, but I'm surprized you can use one where the screw goes into a plastic casing... doesn't it damage the master cylinder?

Plastic...? the reservoirs are cast ally....no, I've learnt to give the the screw a tap with an impact driver before even thinking about a screwdriver.

If it were plastic surely the screw wouldn't have corroded in in the first place..?
