Thanks for the info! I don't know anything about the part your talking about but I'll do the best that I can to figure it out. I put some more brake fluid in the resivour - which could have been a tad low - last night and drove home from work and it didn't do it until I cranked her up around 10am(2hrs later) and it did it again. Brakes work fine until I'm almost stopped.... Then it's that 1" drop of the pedal towards the end of braking - it feels and sounds like I'm crushing a stack of Ritz crackers beneath my foot while the pedal is dropping... Then I keep pushing the brake down and it finally stops. Yeeeesh!!!! I'm going to look into that tone ring in the mean time though. Thank you for your input!!!
