Brake noise when turning right

[mvr]

Ive noticed that lately I've been getting some brake noise in the front left rotor when I'm turning right.

Its very noticeable because I have Hawk HP+'s so they do make some noise....problem is that I'm not even applying the brakes when the noise occurs.

Any ideas whats going wonky? I'm thinking wheel bearings...but dont really have a clue.

if its a whirr noise it could be wheel bearings. a metal on metal noise is brakes. You could have a sticky piston and the pads are loose, causing them to rub on turns

Start even cheaper. Turn your wheel all the way to the right (like where you would start hearing the noise) and look at the metal dust shield on the back of the rotor. If it's even close to the rotor with the steering maxed out it can rub on the rotor while turning. Just bend it back a little and that should fix it. Same thing happened to me when I replaced my control arms. If that's not the case, then move onto the next cheapest thing (the grease suggestion). My two cents.

Sorry my brain is not awake yet.

Can you explain the noise more specifically? It could also be a CV axle if it only occurs on turns

This isnt too difficult to diagnose. All you need is a jack, and two jack stands.

Put your front end on jack stands, but put the jacks under your control arms with a piece of wood or rubber between them. Put the car in neutral, turn the wheel to where is makes noise, and then spin the wheel that you think is noisy (with your hands). Once you discover your sound, figure out where it is coming from. This can be done with an automotive stethoscope, or just use a long screw driver by putting the bit end on a part (bearing, knuckle, ball joint, caliper) and your ear to the handle, while the wheel is being spun.

If you cant discover the noise this way, it's likely in your suspension, but I doubt it. Check your rotors for strange wear patterns. Had this happen once with a brake pad clip that had a mind of it's own.

Just to clarify, it is in fact noise coming from the brakes. Makes more noise when the brake is hot too which I have found consistent with the type of brake pads I have.

I just dont know if it is because something is bent/broken, or if its because something just needs adjusting.

I just want to see if its something I can fix myself as opposed to going to a mechanic to fix it for me.

I'll probably try the dust plate/grease suggestion this weekend.

Then based on what you say it sounds like a sticky piston. Your brake pads are probably loose

How long have you had the pads/rotors on there for?

They may just need servicing (cleaning & lube). Sometimes old material can build up in undesired spots on the pads and causes noises similar to those that make people think their brakes are toast. A simple clean up and lubrication is sometimes all that's needed. Should be done once a year regardless of any noises.

Thanks guys,

I will clean and lube pistons. I dont think it was done when the brake pads were put in... I noticed that they made more noise immediately after hard braking too...

I've had the rotors and pads for approx 8 months.

Good advice.

mvr, your pistons don't need lube. He is talking about your sliders and pad journals (where the pads sit in the caliper mount).

Send me a private message if you want, I'm in Scarborough and available during the day if you'd like someone to look at it, free of cost.

^This. Don't lube the actual piston lol. Sorry for not being more specific.

Took it to the shop, got the ball joints/wheel bearings checked and everything looked good.

Looks like the brake pad backing plate or the caliper mount (I forget what he said) was rubbing on the edge of the rotor (where the rust builds up). I have non-OEM rotors and non-OEM brake pads so possibly there are clearance issues. It only really happens after I brake hard ...
