Okay cool. I did DOT 4, but I'll keep in mind that maybe I should run DOT 5. I didn't know about the heat rating. I've learned a lot today. lol

The reservoir on the handlebars says DOT 4.... Do you recommend DOT 5?

SlammedRanger, Thanks a ton. I bled the brakes, and got all of that black fluid out of there. For now it seems to be doing really well. Hopefully that's all it was.

I didn't, and I knew I should have done something like that! The YouTube videos I watched showed nothing like that, so I went against my better judgment. I'll look for this reservoir. I should mention that the front brakes are working fine though... Is the master cylinder just for the rear brakes?

Can an admin move this to the correct section since I'm an idiot?

I had the hardest time changing the rear brakes on my 400 right now. Turned out, I had to back off the emergency brake to get the pads to have enough space to fit the rotor in between them. When I was backing off the emergency brake, I broke that rubber boot that sits right there, and some brake fluid came out. Not a lot but enough that I knew it was broken. When I put everything back together, I have no pressure on that rear brake. The emergency brake works great, and I adjusted it back where it needs to be... But the foot pedal goes straight down and has no pressure. I tried pumping it, to no avail. There's no fluid visibly coming out of the cracked boot, but I suspect that's my issue. What do I need to replace? Edit: 2005 HONDA TRX400EX
