master cylinder

Got a new master cylinder,need to add fluid and bleed the line,not sure how to do this?

I assume this is for your front brakes so here's how to do it.

1 - Install the master cylinder and add brake fluid.

2 - Pull the brake lever several times until you feel a slight build-up of resistance. DO NOT RELEASE THE LEVER. With the lever still squeezed, you must 'crack open' the bleed valve on the brake unit at the wheel. Fluid will rush out (have a pan under it) and the brake lever will then 'release' and squeeze in until it hits the hand grip. AGAIN - DO NOT RELEASE THE BRAKE LEVER UNTIL YOU TIGHTEN THE BLEED VALVE BACK CLOSED or you'll suck air back into the line.

3 - You may notice the brake fluid coming out of the bleed valve 'squirts and sputters' like it has air in it . . .well it does. That's what we're trying to clear out here. Make sure you DON'T RUN OUT OF BRAKE FLUID IN THE MASTER CYLINDER while doing step 2. Add more as needed.

4 - Repeat step 2 until there is only PURE FLUID (no air) coming out.

5 - You can tell when you've completed the process correctly when you squeeze the brake lever and it moves in a little and then tightens up until you can barely pull it anymore. If there is still air in the line the brake lever will feel 'spongy' as you squeeze it tightly.

It's actually very easy. It may be easier with two people. Good luck!

You're assumption is very probably correct - stuck or damaged floats. I cleaned my carbs on my bikes in different ways. On one I just used the common 'Carb and Choke' cleaner spray you can find at any Wal-mart or auto parts store, but make sure and wear protective gloves and glasses because it really is pretty nasty stuff. On another bike I boiled the carb parts in lemon juice for about 10 - 15 minutes. You'll need compressed air to properly blow out all the little passageways.

There are many "How To" tutorials on the internet. Just type in 'How To Clean Your Carbs" and it should bring up a ton of sites. Good luck.
