Tip: Bleed your Brakes

Yard Sale · July 16, 2008, 03:58:10 PM

Bleed your brakes before every track day. Not just to remove air, but to replace the old fluid. Old fluid causes brake fade.

I had a lot of brake fade on both my 250 and 600 recently, and bleeding cured it. So I decided to bleed brakes every other track weekend. I guess that wasn't enough and I suffered brake fade on my 250 this weekend. So I'm now going to bleed brakes between every track weekend.

good to know man.....thanks.

.......what kind of brake fluid do you use for track days?

Motul RBF600 seems to be more fade resistant than the auto parts store stuff.

A change out after every day on the track? That seems kinda goofy. I use RBF as well. ....and this charter BS is killing me!

Bleed between every track event. It only seems excessive until your lever is coming back to your bar and you aren't slowing down.

It will probably be less of an issue once the weather cools down. The fade is caused by the boiling of the fluid. Hard braking is what causes the boiling but the high ambient temperatures make it worse. I've been having the same issue.

is there any place in reno that sells RBF600?

Anybody that carries Motul products should have it. I think I picked some up at Michaels and I've been buying Motul premix oil at RMS.

Maybe since I'm doing this every event now plain old Castrol DOT4 is OK...

Hey bring your bleder to the Track and suggest that in Tech. That would be pretty cool to do. Just don't mess it up. You could Kill a Track Day Customer.(TDC) I willl aslo be using you in Tech too Eric if your available.

I wish to amend my original tip. Don't use an old bottle of fluid that has been opened and then sat on the shelf. Brake fluid that has sat around for a year sucking moisture out of the air is going to cause brake fade no matter how often you change it.

Yeah so I got brake fade Saturday with my freshly bled brakes. Bled with the last of an old bottle of fluid. Bleeding at lunch time with from fresh bottle of fluid stopped the fade.
