Hello. I’m a new rider who recently purchased a ten year old bike. I have ZERO mechanical know how, but decided that I wanted to learn.
So far I managed to take both the front and rear wheels off to get the tires changed and I managed to change the oil. Since I am unskilled, it took a LOT of fumbling through these to get things going…including breaking some nuts (rear axle nut was stuck and I originally only had a 12 point socket) and bolts (overtorqued an oil filter cover bolt despite using a torque wrench) and buying replacement ones.
Since the bike is 10 years old, I know that all of the fluids need to be changed. I feel comfortable attempting the actual change for the brake fluid from my research EXCEPT I don’t want to irreparably damage this area. The front brake works fine, but the sight glass is totally clouded and opaque, so I cannot visually check the condition or level of the fluid.
These are JIS screws and I have purchased replacement screws. Any advice here? Please consider my novice skill level lol.
I bought some screw extractor bits but do not have an impact driver. I have some JIS screwdrivers, a hammer, a regular drill, penetrating oil, and replacement JIS screws.
Thanks!


Year make model? I bet i can find one cheaper than $100. Changing a brake master is pretty easy: remove, replace, fill, bleed. I can walk you through it.
It’s a 2017 Honda Rebel 300 (non ABS). The part number seems to be 45510-K87-A01.
When googling, I do see some websites that sell it for cheaper, but idk how much I can trust these random sellers I have never heard of lol. More also that I don’t want to keep being out for riding for so long! It took me several weeks to get parts together to get the tires replaced. I’m a new rider and want to be able to practice haha!
Okay, best I could do is get a used one off ebay for ~$50 and a rebuild kit for ~$30. If necessary, that’s the route I’d go myself.
