What's the procedure for flushing the brake fluid on the 950? Can't find a thread on it.
See pretty straight-forward based on the manual, page 12-11:
Changing the rear brake fluid
Unscrew the cover on the brake fluid reservoirs 1 and remove
together with the diaphragm 2.
Use a syringe to extract the used brake fluid and add fresh DOT 5.1
brake fluid (Motorex Brake Fluid DOT 5.1).
Press the brake caliper pistons all the way back..
Use a commercial extractor (shop equipment) to extract the used
brake fluid out of the system through the bleeder screw 3 on the
brake caliper. Make sure the brake fluid reservoir is always filled with
enough fresh brake fluid.
Tighten the bleeder screw again.
If you have a mighty vac it makes the job a whole lot easier!
I can blead all the brakes on a bike in about 1 hour
When I was stationed at Lackland about a million years ago, we used to go to a park that we referred to as "Stinky Falls" to go tubing. Izzit still there or has it been developed into something else?
I just did mine, super easy. I bought a one man brake bleeder gizmo at NAPA, about 5 bucks.
Suck all the old fluid out of the Master cyl.
put bleeder on nipple (the bike numbnuts) of left caliper.
Fill MC with fresh 5.1 fluid.
Pull brake lever, at same time open up bleeder screw. Before brake handle bottoms out, close bleeder nipple. Repeat until fluid runs clear with no bubbles. If the handle bottoms out before you close the nipple, it will suck ait back into the lines, bad.
Keep a close eye on the level in the MC, if it starts sucking air, you need to start over.
Always start with the caliper farthest away from MC, in this case, the left side as sitting on bike.
It helps to have two people, but I did mine solo.
Be sure not to spill the fluid, corrodes paint.
Obviously put catch bottle under hose to avaoid spills.
I noticed the rear MC cover said DOT 4, but I used the Motorex 5.1 anyway. Not sure if this was a bad thing.
When I was done, I was amazed at how much firmer the lever felt. Much tighter.
Rear is same as front, only easier.
