Hi Guys, next week i will change the original brake pads to EBC Sinter pads... So on i also will change the brake fluid (over 2 years old) - can I use DOT 5.1 brake fluid or will it ruin my braking system? Are there all seals suitable for that? Thanks in advance, best regards Kevin | ||

If I'm not mistaken, DOT 5.1 is chemically compatible with DOT 3 and DOT 4. It's the DOT 5 stuff you have to watch out for, it's a completely different chemical make up. | ||

Like Jaimec said, as long as the fluid itself says it is compatible with DOT4, you should be fine. It should say on the bottle specifically what fluids it is compatible with. I usually use the synthetic stuff that says it is DOT3/4 compatible and have never had any problems. | ||

Plus, DOT 5.1 has a higher temp rating. I'm planning on using it too cause last time on the track I could definitely feel the effects of super hot brake fluid. | ||

Sure..go ahead an use it..lol J/k Just use a High quality DOT 4. Motul 600 Motul RBF 600 http://www.amazon.com/Motul-RBF-Racing-Brake-Fluid /dp/B000AURZ08 or http://www.amazon.com/Brake-Fluids-Castrol-SRF-Flu id/dp/B000JL760C Exceptionally high dry boiling point of 590ºF (Wet 518ºF) | ||

Do not use any Dot 5 stuff. Dot 4 is much, much better. Dot 5 gets air bubbles and causes spongy levers. | ||

Good info on brake fluids and some high performance recommendations... http://www.stoptech.com/tech_info/wp_brakefluid_1a .shtml | ||

http://www.stoptech.com/tech_info/wp_brakefluidcom parison.shtml That Castrol SRF looks like it might be a huge help for folks experiencing brake fade. If true, the wet boiling point is impressive. | ||

"Do not use any Dot 5 stuff. Dot 4 is much, much better. Dot 5 gets air bubbles and causes spongy levers." *sigh* my X1 calls for DOT5. Wonder what it takes to switch to DOT4? | ||

Hoot: You have to flush your entire system to put DOT4 (or 3 or 5.1) in a DOT5 system. The two will "mix" and make a "gel" in your system if it is not properly flushed. Usually guys use denatured alcohol to flush the system but some people don't agree with that. Some say just run a ton of DOT4 through the system to make sure all the DOT5 is out. | ||

Definatly go for the RBF600. I run that stuff in my hand and foot brake on my stunt bike, and even in the super hot summer days of dragging my brake for 20 minutes at at time, ive never got it to boil. | ||

That's a good endorsement Incognito. I'm going to swap the RBF in before my next track day. | ||

Yep. I had a really bad experience with boiling brake fluid. It costed me 2 weeks of not being able to walk and my new bike. I realized after that just how important good brake fluid really is. 18 bucks for a bottle of RBF600 is well worth it in my opinion. |
