emergency parts?

[clutz003]

I put on a new Galfer front brake line yesterday. I primed the line with brake fluid before tightening the bottom banjo bolt then filled up the master cylinder with fluid and began the bleeding process. I can't get any resistance on the brake lever. There appears to be fluid throughout the system, as when I take out the bleeder valve fluid runs out of the hole. When I open the valve and depress the lever only a very small amount of fluid comes out. There is not nearly enough pressure to even think about using the speed bleeder. I let it set overnight with the lever fully compressed (recommended per review of the archives) but still the same story today. Any suggestions? Thanks, Craig A18 San Jose CA

Craig - One suggestion I have is to leave it overnight with the lever "bungeed" again, but make sure the bike is upright. Don't leave it on its sidestand. Leave it either on its centerstand (if you have one) or on a jack (if you have one). It's been a while since I changed my lines, but it seems like that really helped. James A15 Dallas, TX

I had to just keep pumping and pumping and pumping until eventually enough fluid made it into the master cylinder so that I could get a good flow going. You might try leaning the bike different when you start pumping to try to let the bubble that's in the master cylinder escape. It took several minutes of pumping, tapping, and wiggling the handlebars (to change the angle of the brake reservoir and master cylinder) to get it to start going, but eventually it did. One problem is that the master cylinder on the KLR opens to the *front* of the reservoir, rather than the *bottom* of the reservoir, so a bubble forms there. So maybe loosening the brake lever and rotating it so that the reservoir is pointing different might help too if all else fails...

<><><><><><><><> <><><><><><><><> Craig, Maybe try opening the bleeder just a tad so it lets fluid out. Then put a thumb or finger over the opening to provide light resistance to fluid coming out. It will also seal the opening preventing air returning to the system through the bleeder. Then repeatedly apply the brake by squeezing and releasing the lever. Don't let the fluid get too low where the master cylinder sucks air. This has worked for me on a few brake systems that were full of air. For whatever it may be worth... I never use speed bleeders although I have heard good things from a few people who have used them with success.

Hi Craig, I had the same problem when I installed a Rusell line, I believe it was due to the fact in my case that the line was a touch longer, not confirmed, causing the highest point in the line was abit higher then the master cylinder trapping air there. I bought on of the little $10 bleed assisting kits and had it done in minutes after trying my normal way for about 30 minutes, this was the first time I had trouble bleeding brakes. I tried the Speed Bleeders, they wouldn't work for me, think I had a defective on....have a great day ....Greg

Craig, It may be that your master cylinder bore has air in it. Here's how to remedy that: Fill the reservoir with fresh brake fluid.Actuate the brake lever while watching the fluid in the reservoir. One or more small bubbles may float to the surface. If so, you need to repeat this action until the bubbles stop appearing. Note, it may take many dozens of applications. The applications don't have to be full stroke. A partial stroke is all that's required.When the bubbles cease to appear, the master cylinder is bled. HTH, Mike Martin, Louisville, KY

Craig, I use a "MityVac" vacuum bleeder, and don't have any problems. Think I bought it at Harbor Freight. Ed

+1 That is the fastest way to bleed a small hydraulic system that there is. We use it for brake systems, clutch systems, and power steering systems in automotive applications. It also lets you know if you have a system leak because it will not achieve and hold a vacuum if there is a leak. We use a large lab style rubber stopper (cork) with a tube inserted into the center of it to attach the MityVac hose to, wet the surface of the stopper with the fluid that the system uses in order to seal it to the reservoir and apply a vacuum. Also if for some reason the master cylinder piston has not fully returned to the rest position it can cover the supply port from the reservoir and not allow fluid to transfer from the reservoir to the rest of the system.

You can also buy a large syringe usually sold for use with animals to fill bottom up, at the caliper. Got mine at a ranch supply store. Bogdan, who hates playing in brake fluid [Non-text portions of this message have been removed]
