Bleeding front brake problems.
Posted December 19, 2005 - 04:57 PM
I have put it all together with a new front brake line, but I'm not getting any brake pressure. I have straightened out the line and pushed brake fluid from the caliper through the brake cylinder. I removed the plunger from the brake cylinder, thinking air was trapped in there. I also worked the plungers in the caliper. There is no fluid dripping out of the system, but then there is no pressure.
The brake worked fine before the race so I don't think a seal is bad, but that's my next direction.
Have I missed something?????

They are a pain in the ass to get right.

I have seen workshops that use vacuum pumps to bleed their brakes. How easy would that be?

I have tried to pull fluid out the bleed screw on the caliper with my B.A syringe, and I get air but I can't tell if the air is coming from around the
bleed screw, from the connection on the syringe, or from the caliper.
I'm going to try again tommorrow, but something is going to give because the weather is getting warmer and I hear Rabbitt Valley calling my name.

Invest in a $25. Mityvac Brake bleeder. It is the best way to bleed and change your brake fluid! A must for any KTM owner front brake bleeding and a great tool for our WRs rear brake bleeding as well.
Agreed. I think I bought mine cheaper than that though.

With the top off the master cylinder, jiggle the hose ,watch for bubbles then sqeeze the brake,repeat several times.

I will have to look around here to get one of those now! The cheapest ones I have seen are about $200. I haven't really looked though.
Those are useless on KTM brakes and no good for flushing out and changing the fluid. One you have a vaccum bleeder you wont go back to pump and release for an hour to change out fluid.
Those work on the WR brakes don't they?

I was hoping that I had forgotten some obvious thing.
Something has been working because I'm getting a clicking sound from the caliper that wasn't happening earlier. Something wants to work.
I'll guess keep trying tommorrow, I've had enough for today.
