Hi there,

I also facing that problem too. However, I did change the brake pad and the disk rotator. but the sound still occur. The funny thing is when i step on the brake it quite. When i release my brake paddle it start again.

Any1 know why

If you hear screeching sound when brake is not applied, it could be the brake caliper is misaligned, thus causing the pads to touch the rotor. get it fixed or else no point changing pads and rotors.

But if you hear metal knocking noise while turning, it could be the 'Orifice Valve' or 'Valve Orifice' (can't remember).. mention this on your next visit to the SC.

Normally how much is the caliper?

hi, i also noticed tht persona ori brake pads "bosch" are not disc friendly.. noticed many are badly scratched by the pads.. even mine too...

davidfts,

no need to change the caliper.. just service.

chrislyv,

i do have a feeling that the original brake pads are not bosch.. it is Mintye (sucks and dusty).. only the brake pad cover is from bosch, but the pad itself is mintye.. coz i always change my pads outside, using Bosch (blue box).. hardly any dust at all!

[chrislyv]

wow cover is bosch & inside mintye? tht's something new 2 me..
anyway i've disposed the front & rear ORI pads although it's still very thick!
already damaged my front "have to skim it" & luckily rear still ok..

Before i replace my brake pads, i always thought that the stock brake pads are from Mintye... but when i go to replace my pads 2 weeks ago, i realize that the stock pads are from Bosch... this gv me a shock... how can a Bosch pads feel so spongy and do not bite AT ALL... Now i'm using RapidStop 550c brake pad... i would say it bite way better than the stock 'Bosch' pad...

am using vetto.. 600c.. vry good but noisy when it's cold..
no problem speeding down from genting which i normally do...

i'm facing the metal-rubbing-with-metal sound with this 550c sometime... izzit because the pad is still cold? normal sound for performance pads under cold condition?

yes most performance pads are like this..
