C900 - Flushing ABS style Brake Fluid

Besides using a good quality fluid and avoiding pushing old, dirty fluid back up in the system, are there any good tips for a DIYer to know when replacing all the brake fluid in a 1991 900?

I'm thinking DOT4 is what's called for, I have a 'One Man Bleeder' device (two actually- one is a tube with a one way valve in-line and the other is a container with two tubes running to it; one tube enters and is held below the surface of the expelled fluid to prevent air bubbles from getting back up the line.)

What 'gotchas' does having ABS installed bring to the mix?

First off, if you don't have a Bentley manual, you should pick one up. It can give you all the details. In summary though: you can pressure bleed the front brakes as usual, but you can use the ABS pump to bleed the rear calipers. You just have to have the ignition on, and get someone to step on the brake pedal while you open the bleeder. You must take care to not let the reservoir get empty in the process, and also don't let the ABS pump run for more than 30 or

45 seconds at a time to avoid overheating the pump.

But get a Bentley manual.

Heh heh.. Thx for some details. I tossed in the virtual laugh because you remind me of Me, but over on the Water-cooled VW newsgroup.

"get a Bentley, Get a Bentley" [squawk!]

Thx again, TBerk poorly imitating parrots.

I think the JohnB's description is clear enough you don't need the Bentley to do this particular task.

Yeah, buuuuuut.

I'm tech support for my bud's newly purchased C900s. It's a matter of getting him to fork over the cash (even for a good used manual .)

Next on the list is front CV joints. Wheeee!

The Bentley for c900 is very good. It is well worth the money even if you buy new. Used is even better. I got rid of mine when my c900 was gone. Again the front CV joint is intuitive enough you don't need the Bentley. You can get the tightening torques by asking the various boards on the internet.
