Hi All,

My new BWS is a little low on brake fluid and I need to top it up, or better
yet, flush the whole thing. I've never touched the brake fluid on it before
(its not that old).. any tips on doing this? Are there any sites out there
with BWS50/Riva II mechanical info on them? I'm having a hard time tracking
down a repair manual.

Thanks.

get brake bleeder kit... 2 hoses and a little cup. take top off master
cylinder. loosen bleed screw and slip tube on. pump brake, while refilling
with fluid. repeat until the fluid coming out the bleeder screw is clear and
has no bubbles. hold brake handle in, tighten bleeder screw. top off master
cylinder, replace top. road test!

And don't forget to change the air in the tires too... Old air compresses
easy, and can lead to premature tire wear!

I reccommend AmsAir Synthetic... it's about $4.50 a pound, but I think it is
well worth it for the peace of mind you'll get!

Go to a dealer, and tell them you need the air exchanged, ...they'll put it
in their special hyperbaric chamber, and extract all the old, nasty air (and
properly recycle it) and refill with pure AmsAir.

the whole process shouldn't cost you more than $80-$100. and you'll feel
like your riding a new scooter!

good luck!

P.S. don't forget to pick up a couple extra cans in case of flats

You spend 100$ on new air for your tires? I guess i am jsut old fashion
using the free air we have all around around us.

What are you smoking, and where can i get some!?

Brake fluid is hydroscopic. It absorbs water over a period of time. Most
manufacturers would recommend changing brake fluid every 3 years because of
this. The theory is that as the fluid gets hot in the cylinder, any water
will vaporise leaving a very spongy brake.
In reality, I wouldn't loose too much sleep over it as long as the brake
feels O.K. and the fluid is not too old.

Changing air in Tires yearly is as important as changing brake fluids... Of
course I change my air and brake fluids regularly... you shoud too, you know
!
Haven't you ever noticed how awful smelling old air is in your tires ?
I like to add a little, lemon juice (or orange depending on how I feel to
mine), just unscrew the valve and pour a few CC of juice or perfume, just
before you pump it up, you'll be glad you did next time you bleed your tires
to add new air !

I have seen 10 year old cars with the original brake fluid in them... still
brakes fine.
I wonder where people get this kind of information ?
If your brake system is properly maintained and no foreign objects or
impurity goes into your brake lines/cylinder.. I cannot see why brake fluid
wouldn't last forever.
If someone tells you, you gotta change your brake fluid (like an oil change
maintenance) Tell 'em to go screw themselves !

you dont HAVE to, but you dont HAVE to change your oil either. just top it
off, and run it.

Yes but the difference is that the manufacturer doesn't void your warranty
if you DONT change the brake fluid, in fact I have yet to see changing brake
fluid on a manufacturer's PM schedule. Engine oil is a *bit* different..

if its still new enough to be under warranty, then the brake fluid should be
ok. on an older scooter go ahead and ignore all the fluids... just top em
off. scoots are disposable anyway.

For what it's worth, the preventive maintenance schedule in the owner's
manual for my Reflex says to replace the brake fluid every 12,000 miles.
