    Brake Fluid Change

    After the last track day (approx 85 miles with speed cycling from 125 to 45 twice in each 1.6 mile lap) I decided to change diff, tranny and engine fuids. These swaps are relatively straight forward and well documented in the FAQ site. I figured that I should do the brake fluid also.

    I picked up a quart of ATE Blue Racing fluid (DOT4, $11) and a Motive power bleeder ($60). The system screws on the master cylinder in place of the cap. After a pressure test, I charged to bleeder with one quart of fresh fluid and pumped to 10-12 psi. I attached the drain tube tothe bleeder screw and ran each wheel until the fluid changed from slightly brown tinged amber, then amber, then blue.

    Time required - about 20 minutes including fooling with pump. I couldn't hold pressure until I wet the gasket with a little brake fluid. I didn't have to call my wife or daughter down to pump the brakes and keep refilling the master cylinder.

    Fluid used - about one pint but I probably flushed more blue than I had to.

    Also, I used some cat litter (yes, clean) to soak up the old brake fluid for disposal.

    Sounds good. Also sounds like it was time to do a flush. I use ATE in the Vette and have had no problems, although someone told me it might be more prone to attract moisture than OEM stuff.
