Issue: Nose Diving during Moderate Braking and Rotors Warping on 2000 Camry CE

I'm looking for information based on experience with this problem. Due to brake shuddering, I replaced the front rotors and pads when I bought my used 2000 Camry CE a few months ago. Braking smoothed out, however, before and after that brake work, the car would nose dive during moderate braking from between 40 & 50mph. I've owned 5 Toyotas over the years, and driven several others, and have not had that problem. It occurred to me that poorly adjusted rear brakes could be the cause of the nose diving, and the parking brake clearly needed adjustment as it would nearly top out before catching. Due to other priorities I delayed the adjustment. After 3 - 5 months, I finally adjusted the rear brakes (drums), however, by that time - the front had resumed some vibration during moderate braking from 40-50mph. The nose diving continued throughout.
Recently, a friend suggested that the nose diving could be resulting from a failed or failing brake metering or combination valve. I've also read forum posts and advertising that indicate that new springs (w/ or w/out new struts) might be required to fix this. Before I spend the money on one or the other, or both, I'd like to learn if anyone knows exactly how to diagnose and resolve the true cause of these issues (nose diving and premature warping of front rotors).

It's highly doubtful the "springs" are bad. I can see bad struts causing the dive though, in fact when I changed my struts, brake dive lowered dramatically. But you may have very little braking power to your rear brakes....making the front do all the work. But I can't help you troubleshoot that one! ;)

Your right. Usually when the car nose dives when braking is caused by bad struts/shocks. I dont know about bad springs. For wraping, its ususally when the front is doing all the work. Wouldnt surprise me i was wrong, but thats what i know.

Ok, thanks TZ and euro. I'd certainly considered the struts. Articles tell me there's a method to use pressure gauges simultaneously connected to front and rear brake lines to diagnose a bad valve. There are specified diffs in pressure that should occur between those two. Anything outside of that range appar indicates a bad valve. However, I also read something that said FWDs with split diagonal systems do not have metering valves since the fronts are supposed to do nearly all of the work in those FWDs. If that's the case with the 2000 CEs, then it would have to be just the struts that allowing my nose dives. It's starting to look like I'm going to have to simply invest in the struts and do the work to see if that's it. <sigh> I'm gettin' lazy.
Thanks for your replies!
