Question:

How do you bleed motorcycle brakes?

I bought the motorcycle bleeder kit with the pump to bleed my rear brakes. My issue right now is that there is no brake fluid coming out when I use the bleeder. The pump works fine because I can feel the suction. The reservoir has plenty of brake fluid. The valve is open. I don't understand why it's not working. This all started a week ago when I changed my brakes myself. I'm pretty sure I did everything correctly, and I don't understand why the brake fluid won't come out. Help please!

Answer:

when I put in braided stainless strains on my Kawasaki, I too had a very stressful time getting each and all of the air out. first of all, vacuum pumps artwork super for vehicle disc brakes, yet for motorbike disc brakes and previous form vehicle drum brakes, they pull air previous the brake piston seals and you in no way get each and all of the air out. I even have one and prefer something, there's a time and place for it yet no longer on motorcycles and vintage automobiles. first of all, with a hose on the bleed screw on the calipers, open the screw one after the different and compress the calipers one after the different till you have the pistons pushed each and each of how in. this might expell as lots air as obtainable. Then particularly loosen the banjo bolt on the mastery cylinder. conserving a brilliant wadded rag under it, loosen the bolt possibly a million/4 turn and pull the lever back each and each of how till fluid flows out of the banjo bolt. Tighten the bolt and then bypass all the way down to the T installation. With a sparkling rag (you do no longer desire to apply the previous rag and drip brake fluid onto the fender), do an identical with the different end of the line coming from the grasp cylinder. Then do the two one among the different fittings on the strains going to the calipers. Then flow all the way down to the calipers and with a hose on the bleed screw, open the screw somewhat, squeeze the brake lever and while you're conserving it back close the screw. launch the brake lever and repeat it over back till no bubbles seem and then bypass to the different one. this might desire to expell each and all of the air. If it nonetheless seems somewhat spongy, attempt parking the motorbike out in the nice and comfortable solar all day and notice if that helps. that's what it took to get each and all of the air out on my Kaw.
First of all, what is the make, model and year of your bike? When you say the reservoir is full, are you talking about the one on the handlbars? Or the one located behind the brake pedal under your right foot? Are you using a hand pump to bleed the brakes or a Mityvac style bleeder that attaches to a compressed air hose? If using a hand pump, are you sure you've got it hooked up correctly to your brake system so that you're sucking fluid down from the reservoir, not blowing air up into the reservoir? Do you have the cover off the reservoir while you're trying to pump fluid?
