Bleeding Disc Brake????

[Carlo C.]

Guys,
I have just about finished everything on my silver CT70 and need some help bleeding the Disc brake, I change the hydraulic line out to a longer one and have tried everything to get this thing to bleed with no luck. It just will not make any pressure.

Please help

You obviously have air in the system. Most people think it's in the line, but often the master cylinder needs priming. Disconnect the brake line from the master cyl (reservoir and lever) add fluid and keep pumping until fluid comes out. Then connect the line and pump til fluid comes out the bleeder. Take care if you're using DOT 3 or 4, it's not kind to painted surfaces. Towels help.

That worked perfect thank you very much for the info. I removed the line from the master cylinder squeezed it in slow, then held the lever in and put my finger over the hole when I let the lever out and it seemed to suck the fluid into the pressure valve. I did that a few times and once it got some pressure I hooked the line back up. With the lid off of the master cylinder i was able to squeeze the handle slowly and watch the air from the line come up with each little squeeze. When the air stopped I finally had some pressure when I squeezed the lever. I then bled the caliper like a normal brake and the air came out in only a couple tries and now it works perfect. I will not be in town this weekend so hopefully when I get back I can pick up the last couple of parts from my powder coat guy and I can go take this thing for a ride and start tuning it. I will post pictures on the other thread once bike is completed.

Thanks again for the help
