Hello smile

Mods please move if this is a bad sub forum.

I've an irritating problem and looking for some ideas. My Rav4 this morning started making an odd rubbing noise when it turns (left). Internally it sounded like plastic rubbing - almost like plastic sheeting caught in the wheels. With the windows down it sounds more metallic, the best way I can describe it is a singing noise as if metal is rubbing metal - but barely contacting.

Happens in various gears, doesn't stop if coasting, not every turn but most. Doesn't happen driving straight but the noise will keep going a few yards after a bend into the straight, even low speeds do this - not tried high speed cornering! Front brake disc was slightly warmer than rear.

Took it to a local garage and they didn't have any luck. Said wheels/wheel bearings etc all good. They did manage to reproduce the sound - it's a little intermittent - but relatively easy to make happen.


So, anybody have any ideas what else it might be or where to start checking?

Have a look at the brake caliper. It could be that the pads are stuck or that the caliper/carrier are not moving properly. A quick strip/clean/grease usually gets it all moving again if this is the case. Make sure you scrape al the crud off all the sliding surfaces before greasing if you do this.

Thanks, I was about to add, on another drive, applying the brakes STOPS the noise, if I brake on and off it'll stop the noise in perfect sync. I had a feel and the front discs are waaaaay hotter than he rear.

I'll try and get a proper look in the light

If the fronts are as you say way hotter that sounds like a sticking/binding caliper.

Itll need the pads taking out to check the pistons not stuck.

Does the Rav4 use pads with the metal wear indicators, the ones that scrap on the disc when the pads need changing?

There are quite a few brake related noises on Rav4's. Grease the backs of the pads and make sure the calliper sliding pins are not sticking.
Could be driveshaft - check in an empty car park on full lock. Applying the brakes means youre not loading the cv joint so the noise may quieten down.
