Master cylinder screws. - CaptainCazador - 17-11-15

I know master cylinder screws like to round off so this time around I wish to have replacements to hand rather than fighting to get minced ones back in until I can obtain replacements.

I have never bled the Fazers brakes but from looking at the screws I think they are M4 X 20mm can anyone confirm this before I place my order?

Thanks.

I can't confirm the size, but would agree with your guess.

I took my originals into the local bolt suppliers and they were able to match them easily, so they aren't anything odd. I switched to ones that need an allen key rather than screw driver, less likely to get chewed up.

+1 on the allen key, stainless with a little copperslip will make sure they come out next time

Thats a silly idea, 6 inch nails punched through the bottom and bent over over is an option

I take it nobody bothered opening the 2nd link I posted above, the one with the same part number as in the 1st link, and the size?

I'm wasted on here. :'(

I bought these for mine as the previous owner had wrecked one of the screws took me ages to get it out.

If you get some "Go Through" screwdrivers and tap the top of the screw driver with a nylon mallet it shocks the corrosion holding the screw in, it also seats the screwdriver tip into the recess more and 9 times out of 10 the screw will come undone.

It also helps to know the difference between a Pozi-drive screw and a Phillips screw and use the appropriate screwdriver so you don't mash up the recess in the first place.

They're probably neither of those but JIS.

Re: Master cylinder screws. - Deefer666 - 23-11-15

JIS = Standard Philips head screws, the problem arises when people do not know the difference and use a Pozi-Drive screwdriver in them. Which will of course chew the recess up.
