I have a x1.That i cant get pressure built up at the lever.I brained the fluid and use the 60 cc syrenge bleeding method to day.It will pump fluid back and fourth.But the lever is soft.Could it be the master cylinder or the calibure.Please help dont know the next step to take. | ||

Benjamin why did you drain the fluid? you can change fluid by bleeding, typicaly a soft lever is caused By malfunction or AIR, read through some of the posts in the KV on this subject I did an over haul and put it in the kv some time ago.. http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=3842&post=795056#POST795056 | ||

In answer to your next step question, get out the fsm and read, then decide the most common brake problem is AIR in the system, a tiny bit causes mushy brakes. on the front caliper the overhaul kit has some "majic grease" consider using it if you over haul the caliper. while the mastercylinder is simple consider a new one if you are not comfortable overhauling it. I would fill and bench bleed that front brake system ( its what I will do next time ) | ||

Thanks for the advise Oldog.I will bench bleed her tomorrow. | ||

Bleeding these brakes can be tricky! I did them 2 days ago it takes a little fiddling to get the air to bleed out. Watch the bleeder carefully if your not paying attention how far you turn the screw you can miss the bleed bubbles, I found that holding the master cover on with rubber thing inside but not installed helped a lot, But i will be doing the overhaul on the caliper soon And the wheel bearings will go on at the same time. | ||

Bleeding brakes are a piece of cake. Trick is to never run the fluid completely dry. If you are sure the air is out of the system, and the lever is still mushy. It could be a simple caliper rebuild kit or a master cylinder rebuild kit. Pretty simple jobs. | ||

thanks guys | ||

Just curiuous...What type of fluid did you use to replace? | ||
| Benjamin314 |
Prestone Dot 4 | ||

I put a new mastercylinder on and used the 60 cc syrenge to push fluid back and forth.Pushing the air bubbles up and out the mastercylinder and into the back of the syrenge.Worked like a charm.Thanks for everyones help! (Message edited by Benjamin314 on August 23, 2009) | ||

You'll need to pump and pump and pump the brake keeping an eye on the reservoir so that it doesn't get too low. When the brake pads finally make contact with the rotor, the lever will start to build up pressure. Until then, you'll get nothing. But that's only after you've pumped and pumped and pumped...  | ||

Draining brake fluid? As already advised. Not a good idea. Flush, not drain. Live and learn. It's how we all gain wisdom. | ||

Ok, three beers into the night so beware... Use the DOT called for on the reservoir. (I have a '97 Cyclone so it might be different.) Your bike uses different calipers than mine... But my 6p were very odd. I've bled LOTS of motorcycle calipers, but these were the worse. I had to suspend the caliper above the master cylinder. My master cylinder was an issue. I tried rebuilding it, but had little luck. I just bought another (new) one for $125. It was worth it. I drained my fluid because what was in the master looked like KY jelly. I think it's a sane thing to do if you don't know what the PO put in the system. Mixing DOT 4 and DOT 5 can be very bad news. Good luck! The brakes are one area that *SHOULD* be fairly straight forward even on our Buells, but I had lots of bad luck on mine... Randy (Message edited by blake on August 24, 2009) | ||

I identified the fluid by using a two eye droppers and two shot glasses.I put dot 4 in one shot glass and then dot 5 in a other.Take a sample out of the master cylinder.And put some in the dot 4 glass and some in the dot 5 glass.When 4 and 5 mix its like oil and water.Thats how i identified the fluid.And the caps on the master cylinders had dot 4 stamped on them.O yea and you will need one more shot glass filled to the rim with Crown Royal.To finish the job.

follow the directions on the reservoir covers. they VERY PLAINLY tell you what to use. don't guess, think or take uncertain advice. the reservoir covers are marked for a reason.......... | ||

dont let the brake lever go all the way to the bar when you open the bleeder, close it up about halfway to the bar oh, and like others have said, dont let the fluid run out in the resevoir. I have never tried it, but supposedly gravity bleeding works as well -g |
