My 2002 4runner has been making some strange sounds related to braking lately. I just got back from a 1000-mile trip and here's what I have been experiencing:

1. When I brake and come to a complete stop, sometimes I will hear something working (sounds like an electic motor) and then it finally stops with a ping coming from the right front rotor (at least that's where it sounds like it is coming from when seated in the driver's seat). Tough to explain, but when it happens, I hear
'vvvvvvvvvvvvvvvvvvvvvr ping"...then all is fine. I feel like there is a motor running the right front caliper and it eventually releases (it is not an abs racheting sound). But that doesn't seem to make sense as far as I can tell - the truck just has brakes, fluid and a master cylinder, right? Or is this sound part of the TCS or some other system? I understand, according to the manual, that we should expect to hear funny noises at start up, but this noise is random, not at start up, and too strange to be normal.

also,

2. The brakes are very touchy, aspecially in the morning. Hit the brakes lightly and the whole truck wants to stop. This may not really be a problem, could be rust developing on the rotors overnight - dunno.

I will pull the right front wheel and make sure everything is looking ok asap. Is there an abs sensor or something that could have a rock in it? Could my caliper be rust bound? <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> Thanks for any input! <img src="/forums/images/graemlins/kewl.gif" alt="" />
