First I thought it was bearing issue but now they've been replaced and noise didn't stop . I Think its the brakes. Front brake gives bit grip when pushing bike around and high pitched shrieking can be heard up to 60km/h. I'll propably switch pads next. Is there anything else I should check from calibers before putting all together?

Look for shiny points on the rotors or wheels, you are looking for signs the spinning parts are touching something fixed. If you look down the centerline of the rotors they should be pretty much centered with the caliper split line (where the two caliper halves meet). If the wheel spacing is not right the wheel could be offset and the rotor is touching the caliper body (not the pads).

Jack it up and spin the wheel to find the noise. Hit the brakes, see if they release. There is a procedure for re-installing the wheel. If you don’t follow it things aren’t centered and can drag. Read your manual.

I had my front tire replaced and the mechanic found out that previous owner had assembled tachometer wheel end wrong. He fixed it while changing tire. That helped bit to reduce squealing. Today i applied little bit copper paste between pads and cylinders and all the noise is gone.:smile2:

Good deal.

if you put a chamfer on the brake pad leading and trailing edges that can often help with squealing.
