After I drive like 10 miles, I can hear a low squeeling sound coming from the wheel like there's something which needs some oil or grease!! I'm not 100% sure if it's from the front wheel or not, but that's my guess since when i stop the car the sound cease. Also, I must be driving really slow to hear it, and when i accellerate, the sound seems to 'accellerate' as well and then i don't hear it more cos of the engine sound which dampens the sound.

Any hints of what this could be?

possibly a wheel bearig - Jack the car up and move the wheel around - if there is any play it will be a ball joint - if its not smooth or is noisy then likely to be a wheel bearing

Could be a seized brake piston slider or seized slider AND worn brake pads.

I've just replaced the brake pads about 3 weeks ago. One of the piston sliders (left wheel) was a bit jammed. We noticed this at the last service (3 weeks ago) and the guy has put some oil in it and then it became smooth. The other brake piston slider seemed to be ok.

What kind of pads did you use ? A mate of mine at work put a set of "Safeline" pads in his Astra a while back, and they squealed so baddly from new that he replaced them again after 2 weeks ...

They really need to be stripped down. It's a fairly common problem for the lower sliders to become stiff. There's a rubber sleeve that goes all the way through the slider hole. Moisture gets under the sleeve and surface rust occurs there. This effectively, reduces the hole diameter and stiffens the slider's action. The oil will only be a tempory fix I'm afraid, they need to be cleaned out and greased. I would get it done sooner rather than later before it turns from a 30 minute job (for both sides) into a 2 hour job like mine was last year

@smotter:
the noise came before the i replaced the brake pads

@mark.T:
the guy who helped me out, had actually stripped it and removed the rust by using a flat screwdriver, and then greased the slider. I perfectly understand your point about the moisture.

I'll take it back to him next Saturday and let you know..

Fair dooos They used emery paper on mine. I couldn't bear to watch them beating my calipers in a vice with a big hammer trying to get the sliders out, so I went and played with the guy's pit bull
