Default You might also consider a Mighty-Vac . . .

Hand-operated vacuum pump. I bought one of these years ago for flushing the brakes and clutch master cylinders on my Gold Wings, I think I paid $25 for the kit.

Well worth it for a one-man show!

are you saying pump them all out dry, then fill the resevoir and bleed-refill-bleed-refill etc?

or suck most of the fluid out of the resevoir, but not bone dry, so no air gets into the system? and then bleed from there?

Do not pump dry, you do not want to get air in there. Remove most of the fluid from the reservoir without letting air in, then fill it, bleed one wheel and fill up again, then bleed the next wheel.

Flushed = bleed until new brake fluid comes through.

Start at passenger rear, then driver rear, then passenger front, then drivers side front as you bleed.

I'm too lazy to go pop the hood and look, but is the opening on the reservoir perfectly round? If so, you should be able to just sit the whole bottle of brake fluid upside down in the opening, and it won't leak. Then you won't have to keep filling it after each wheel. If you are really good you won't even spill much when removing it. Just make sure to clean up any if you do spill it...

According to the rave manual on a right hand drive truck its

1. Front left passenger wheel
2. Front right drivers wheel
3. Rear left passenger wheel
4. rear right passenger wheel.
