Default Brake Fluid Questions

I have a 98 C5 and the brake fluid looks like used motor oil. Don't seem to be having any problems braking yet but will be replacing pads and rotors soon so I want to flush out the old fluid and put in new. Does anyone have a procedure that tells how to flush out old fluid and put in new? Also your recommendation for replacement fluid...the best I'm looking for.

Thanks for any help.

My one recommendation for sure is to get some Speed Bleeders...they make a world of difference in doing this job.

I used the Valvoline synthetic brake fluid

I'm currently considering the same thing. I've been contemplating buying a Motive power bleeder. Anyone have any experience using one of these? I figure if I can do the bleeding by myself, it will save a fight with the wife (after all how hard is it to pump the brakes and when I say hold it, HOLD IT).

I use a fluid designed for racing which might not be the best choice for a daily driver, but with regard to your flushing procedure, a power bleeder such as that mentioned above will work well, but won't get the ABS lines. A Tech 2 is required for that.

I myself use a simple feed and bleed type approach. I suck the fluid out of the reservoir and replace with new fluid. Bleed each wheel until clean fluid comes out (making sure not to drain the reservoir in the process), go out and drive the car activating ABS a few times, then bleed again. This is probably a 95% solution with no special tools or equipment needed other than a 10mm wrench and a bottle and hose for the fluid to drain into.

speaking of the bleed/feed method...along with my speed bleeders I get a piece of clear tubing from Home Depot to slip onto the end of the bleeder valve to direct the fluid into a container
