If you were overflowing that would indicate that you pretty much superheated the entire brake system! That's actually a problem with street/track combo pads. The problem is that they get their great bite by using really high operating temperatures, I've seen some R4S's get really really hot. I find that real track pads actually run cooler, and are easier on rotors, after they are hot. (hot for track pads is still hot, just not as hot as combo street/track pads) I think this is why we see more warping problems once you start driving combo street/track pads hard, too. -kit, driving daily with cool willys and getting embarrassed by the garbage truck wail when he stops -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .

(I'm jumping back in after 3 days instructing at Laguna & Sears Point.) Chester is correct, if you pull the seat belt all the way out, it will ratchet back in, securing the child seat. Most modern cars have this. Also, the rear belts on the sedan are mounted inboard, not at the C pillar. And finally, I didn't realize the original poster had a coupe. Sorry.

Should I fight to get them to pay for OEM? The aftermarket has a lifetime warrantee, not sure yet if it has plastic tanks or not.

Via my new Internet-diagnostics software, I have been able to determine the problem...;-) Seriously, since I run my car (the yellow and blue race car) on stock brakes (race pads), here is my diagnosis. The key question is whether the pedal is SOFTER or LOWER (when it gets firm). My guess is that the pedal is lower: 1) You have worn down your pads. As they get thinner, the pedal gets lower. I believe the maser cylinder is supposed to eliminate this, but it never really does. 2) You may have some minor bubbles in the fluid, as this nearly always happens, so bleeding will help stiffen the pedal but not raise it any. If the car is under warranty, just complain to your dealer about a soft brake (ignore what you have done and take off the numbers). Saying the brakes pulse is a good line to get them to check things out. Dan

#6. post-driving school brake fade - from McCarthy, Brian

Date: Mon, 4 Nov 2002 10:52:01 -0800 From: "McCarthy, Brian" <Brian.McCarthy@intermec.com> Subject: post-driving school brake fade All, Both Jon and Peter mention PEDAL TRAVEL. What a coincidence! Just this weekend, I changed back from PF97 pads to the stock pads, and pedal travel is farther than before. Like Peter, I'm looking for advice on what it could be. After my test drive (from changing the pads), I removed the wheels and inspected the job. All the pads were riding on the rotor - no opportunity for pad travel when the pedal is depressed. Dead end. My PF97 pads are still thick, with 80% life left. The stock pads are getting thin, with 20% life left. Jon was at a 2 day track, giving him a chance to really wear down his pads. Maybe thin pads are the culprit? But I (hope I) know better than that. My favorite theory now is coated rotors. The PF97 residue will need a few weeks to get off. In the meantime, more pad pressure is required. Hence, more pedal travel to create more pad pressure. My brake pedal travels below the gas pedal.

If you had the fluid reservoir very full, you'll get some overflow as you use the brakes quite a bit (wether it's heat or pressure related, I'm not sure).Keeping the level just below the max mark seems to cure that. My 2 cents, Jim Bassett

You'll never get that coating off entirely unless you cut the rotors. The new coating will make stock pads horrible and even a bit dangerous. My recommendation is to spring for the $40 brembo rotors and swap them out for street/track pads. Chester ===== __________________________________________________ Do you Yahoo!?
