Persistent but intermittent grinding brake problem

[kevcules]

Yes...most calipers can be pushed back with a C-clamp. It's good idea to remove the brake reservoir cap first and slowly compress the clamp all the way back.

I don't know if this is the right place to discus this. My 2006 Limited, which I just purchased for my wife, is a fantastic vehicle. We bought it from a little old lady who was the first owner. The proverbial ideal scenario.

Just a few days ago I when coming to a stop under medium braking (subjective I know) there was a tremendous grinding and a noticeable vibration just as the vehicle came to a stop. I could reproduce it almost every time unless I braked lightly. I was on the highway the other day and suddenly there it was again (without the braking and at highway speed) and it noticeably slowed us down. It lasted only a couple of seconds and then stopped with no bells, alarms, dash lights, and only one frightened wife.

Since then there has been no noise, nothing. Braking is s.o.p. However, yesterday the 4wd light came on and remains on. Having had new snow this past week, some of the side streets are messy. Without having anyone standing outside and watching, it seems that the 4wd does not engage when required.

Anyone have any ideas?

Thanks.
Happy Rav owner

While no damage occurs with the RAV4 brakes doing this, the advantage of opening the bleeder is that you are not pushing old moist fluid from the wheel cylinder back into the system.
