TT250 Front Brake Master Cylinder Cover Screws
Bleeding the brakes today and I had the same problem a couple other people on here had of one of the screws that hold the break fluid reservoir cover on not wanting to come out. Since the screws appear to made of a metal with a hardness akin to cheddar cheese, the Phillips head stripped of course. >:( In case this happens to you, the replacement screw size you need is a metric one. The size is M4 -.70 x 12. I found some at Lowe's.

J.I.S. Phillips screw drivers
When I had my KLR650 it was very easy to strip out the head of the Phillips screws on the front brake master cylinder cover. A friend told me to purchase some assorted size Japanese Industry Standard Phillips screwdrivers to handle the removal of Asian Phillips fasteners on the master cylinder and the carburetor.
Solved a problem. :clap: |
^That! Believe it or not, there are different types of phillips, and most metric threaded phillips screws use JIP Phillips heads. Use an SAE screwdriver on a JIP screw, and it will strip out rather easily, especially if it is made of a cheap material or aged. SAE Phillips heads are shaped differently, and only contact a small part of the JIP phillips grooves.
Also, a fun little tech tip. Don't crank down on them when you put the cover back on. Nice and snug is all it should take. Most people over tighten those screws. |
As said most of those small screws are not philips but JIP..
JIP screws have a small dot on the head.. "in most cases" get a few JIP screw drives... They say if you put a little dap of grinding paste on the screw driver point helps it to grip better... never tryed it myself..& I have no idea who "They" are... possably just some more internet BS... but might be worth a try... .. |
Impact driver is the best way to go, got mine out no problem :)
Thanks for the size info thoough in case I end up stripping them at some point lol. |
all my bikes go back togeather with anti seize...
Honda moly paste on any thing that gets hot & CRC Lanocote on eveything ealse.. even grease is better than putting them back in dry.. just a little dap at the start of the thread... you don't need half a container on each bolt... .. |

This is caused by a little bit of the brake fluid going down one of the holes (usually the inner hole) upon assembly and then the screw gets corroded in place.
I used a small rechargeable impact to get mine out. Contact CSC. They'll send you new ones under warranty.. |
I use my little impact driver on every screw I try to remove that gives me the least bit of problem with a regular screw driver. No more stripped screws ever.
This is the one I have but the one sold by Harbor Freight would be just as good/useful. Make sure you purchase some of the impact nut drivers also from Harbor Freight. https://www.amazon.com/Hitachi-WH18D...+impact+driver http://www.harborfreight.com/catalog...=impact+driver / |
