Hey everybody,

I just carried out a brake fluid change on my 2013 Ninja 300 SE ABS front and rear brake. The front reservoir screws were a pain - as they were very soft and stuck I stripped them and then had to drill them out and replace them. I couldn't find information on these screws anywhere so had to measure them up myself. They are M4 x 12mm countersunk. I ended up having to order them from Queensland. They came in a much harder zinc coated (corrosion resistant?) steel with a choice of drive. I ended up opting for flathead just so I don't risk stripping them again but I also have allen key ones in case I feel like changing them.

Hope this helps Ninja riders who face this issue in future.

My man. Thank you so much, I had exactly the same problem

I've used a Torx bit jammed into the opening to remove them if they are chewed-up. Works sometimes, and is safer than drilling.

We have used stainless steel M4 x 12mm flat-head (Allen head) socket screws. Coat the threads with blue threadlocker to prevent corrosion.

LOL. Did exactly the same thing last week, striped the two bolts on the front brake reservoir.
The OEM parts on line shop would charge me $16 for the two little suckers. I went to home depot and found some decent SS 4mm phillps head that fit perfectly. 50c each.
Probably a good idea to replace them more often.

I also drilled and used the extractor to pull them out, but the torx system seems a better idea.

I don't think there are any fasteners on a cycle that are more prone to corroding and seizing.

Chances are, if they haven't been removed recently, they are going to get chewed-up on the way out.
