I always do my own work on my bikes, but im not a huge fan of messing with brakes since they're extremely crucial. I have a buddy who is a very good mechanic, he does all the work on my cars and does a great job, so I let him do the pads and fluid on my 1125. Turns out that he used DOT5 instead of DOT4 like he should have...he said it had a higher boiling point, but it still pissed me off. So basically, I rode the bike very cautiously because ive heard of people doing this exact thing and their seals being eaten away, then they have no brakes. Ive ridden it for a couple months and the brakes still feel fine, but im about to go straight track bike and want this thing in top notch condition. So there are probably a few options on what I can do, but id rather get some input on which one would be best. 1. Have someone flush the entire brake system very thoroughly, and refill with DOT4 like it should be. 2. Replace all the seals in the calipers and masters and replace with DOT4 (not sure how much this would cost/how much of a pita it would be) 3. Replace everything (would be annoying expensive) I really want to get this thing back to DOT4 where I can just use RBF600 and not have to worry about it.. Side note: not sure if he used DOT5 in the clutch or not, but how big of a deal is that also? | ||

Are you sure it is DOT5 and not DOT5.1? | ||

DOT 5 is silicone based and not legal on many tracks. And yes, some seals and o-rings are not compatible with DOT 5 and will in fact deteriorate and fail at the worst possible time and place. DOT 4 or 5.1 are what you should use for both brakes and clutch. The Motul RBF is muy bueno. | ||

I would recommend getting comfortable with wrenching on the brake system if you are going track bike. There will be times when you will need to do a bleed, etc in the pits. It's very simple and quick process, everyone should know how to do it. | ||

Im not uncomfortable doing it, I just let this guy do it because hes got a quick bleeder and all that jazz....so would I be ok to just flush the system out really good?? | ||

quick bleeder is $25. Just invest and DIY | ||

You know, it's not all that bad, honestly. Go ahead and get a caliper piston and seals kit from EBR. Cost is like $55. Split the caliper, clean and rebuild it. It will perform like new. Flush the SS line with alcohol then cheap dot 4 then use your RBF600. You can use your existing MC as a pump. Replace the OEM MC with an R6 OEM Brembo or an aftermarket brembo RCS19 or other. $250-$350. The reality of the OEM MC on the 1125 is it's a pretty low quality part and doesn't perform well on the track, anyway. Even without the DOT5 mishap, if you are any kind of rider at all it's a failure waiting to happen. No one making serious track days of the 1125 is using the OEM MC. | ||
