front brakes help

[bikerzx7r1981]

Hi All,

I have just got to the brakes on my GS1000g Project and had a few problems with bleed nipples siezed etc. so after buying a new caliper and tapping the other i put new pads in. I bled the back brake fine.

The front brakes have never had any fluid in them when I got the bike and the brake lever didnt have anything.. no resistance but I put this down to their being no fluid in it.

I have put some fulid in it, but the brake just doesn't pump anything. I have a feeling that the brake master cyclinder may be goosed.

I'm not sure how to check as it seems sealed. Does the brake lever push some sort of piston within the master cylinder? I can see a pad that looks like it would do this, and tried to push it with a screw driver but its' going no where.

Also their are two wires on the bottom...anyone know what these are for ?


Is it a case I need to buy another one? does anyone know if any other gs models may fit .. just so I have more to search for.

Any help much appreciated on this money pit project!

You are taking a risk by using 30 year old brake parts that have not been stripped down for cleaning and inspection. That said, often times the system will start pumping as soon as you prime it. Drawing a vacuum on one of the caliper nipples, to pull fluid out of the reservoir and into the master cylinder bore, typically primes the system and starts it pumping assuming the master is not all gunked up.

Lastly, please watch where you post your threads. We have a brake forum which is the appropriate place for threads like this.

Good luck.

Hi,

I found this on some guy's website. It might help. You can also search the forum for brake bleeding tips.
