My son and I put drilled rotors and new ceramic pads on his 97 Cavalier Z-24 tonight. When I went to remove some brake fluid from the master cylinder reservoir I noticed the brake fluid was green. Is Dot 4 fluid green? The lame instructions that came with the pads and rotors talked about Dot 4 fluid so I'm assuming the newer cars uses 4 instead of 3. Now the good part, should I try Dot 4 fluid (the green stuff I think) in my 70 AMC Javelin or will the Dot 4 stuff eat my seals? Any one try this? Armand
