Braking issue

[lukel95]

Could be sand trapped in between, or your pads near finish the indicator touching the disc?

But it's always made that noise, even when the garage fitted new discs and brakes

agree with uncleVR.
I not sure about trumpet sound, my wild guess. Might be caliper release too slow.

get your regular workshop to inspect caliper piston and handbrake.

Oh! New disc and pads fitted. Then need to take out and check, maybe service the pins and sand the pads before fitting back....

Okay thank you, any specific grit of sand paper?

No need too rough, just need to smoothen the pads surface and get rid of any debris stuck on it.....

service your calipers while you're at it. And check for brake pad material depth.

After reading more abt the problem description i am starting to think its the rotor cover that is causing the problem. Happen before to me on a Neo CPS.
the rotor cover dislodged and scrape the brake disc.check on the inner side of the disc,most probably there is already uneven wear on the inside. When i encounter the problem it will happen during and after braking and while turning full lock.
the rotor cover needs some muscle to put back into place.

By cover do you mean the heat/splash shield behind the rotor, I have checked that before and wasn't touching it but I'll have another look, can you take them off or are they nessecary to keep on?

remove the tire when u want to check.
check properly on the inner side of the disc and the rotor cover which faces the inner side of the disc.
yours could be at early stage so no holes yet on the rotor cover.

another issue could come from cheap aftermarket pad which is not flat.
either the outer circle or the inner circle of the disc will come into contact with the pad when you step on the brake. this is worse as you wont have full brake power when u needs it.

a jammed brake piston can causes such problem too but most of the time you will have overheated brake.
