Anyone else having problems while practicing stoppies with the frontbrake?

After a couple of stoppies, the lever takes further and further in and after a while I can push it all the way to the handlebar. BUT, the brake still grabs good but I can only feel the pressure further in, almost like some air gets in or something, but then it shouldnt grab any good...


I have steelbraided brakelines, new and good brake fluid (Motul RBF600) and I have tried both 03-04 636 front master and 1000rr master.

Can it be my pads that cant handle the heat?

 

This happens to me often and I wondered what it was as well. I am using rbf600, stock lines and OEM pads

 

maybe you need to rebuild the master cylinder however it doesnt make since when you switched masters.. unlikely for 3 master to let in air

 

do you have a good brake bleeding kit?

 

Check the resorvoir that the outlet to the hose isn't at an angle while doing a stoppie that would let air out of the res. into the master...

 

Pads are major... If ur plowing them (rolling low) then yes its prob that. Use stock pads.

Ur problem is prob the lines, as the rubber ones swell with heat. The fluid ur using has a higher boiling rate but the stock rubber lines make ur brakes go to poop after u have been rolling for a while

 

I plow too, so it could be either

 

Problem solved

 

Plowing, air in lines, bad fluid, stock lines, **** pads.

All causes

 

I hate brakes in general

 

Me too... thats why I like to coast

 

Im gonna change pads tomorow to see if thats the problem.

I got this problem aswell last time when I rode some curbs. I also tried changing the position of the reservoir.

 

Do you pump the brakes and it gets stronger?

 

when you heat your brake fluid [yes even rbf] alot you will get brake fade sooner and sooner , change your brake fluid

 

What brake fluid are u using??? Ive seen ppl use DOT3 and there **** go out after a couple of runs. They have different heat ratings.

 

mines the opposite,brake gets stronger and stronger(lever engages sooner) the more stoppies I do,unfortunatly my tires gets worse and worse the hotter it gets

 

mine to and it drives me crazy!

 

air in the lines or your over filling it
