.beri panny dat wan. the objective of washing the machined surface with soap and water is not for sanitation. it is for removal of unwanted powdery metal from machining. if you resurface the rotors, or deglaze the engine block cylinder, or lap the valves (grind valves as many people call it), you have to remove the unwanted remnants of the machining process. in your case, the cast iron dust if not removed, will cling to the brake pads and cause the brake squeal because of the sliding cast iron brake rotor and the cast iron dust coated brake pads making friction.

2 klase ba yun general ct? san kayo nakakuha?

meron ako gusto i-try ferodo zero kaso yun natanungan ko na shop sa banawe by order daw yun.

old stock yung nakuha ko na general CT na walang canal. sa partstar ko binili. matagal din ako nagtiis sa linis-linis ng brake pad until nabwisit ako at pinalitan ko nung bagong taon. bumili ako nung may canal sa toyorama banawe.

dati nga akala ko warped lang rotors ko kaya pinareface ko pa. kaso 1 week lang bumalik ang tunog kaya pinalitan ko na yung brake pad.

*Retz yes update ko kayo pag nasubukan ko na yun ibang methods. matagal tagal ko na din kasi problem to.

*jick kaso paps hindi ko lam kung ano unahin ko. bumili ng bagong brake pads or resurface? or both? hehe. mejo on a tight budget kasi ako ngayon eh. pwede kaya unahin muna brake pads.

*sirkosero yun nakakabit sakin na bendix may canal na eh. siguro try ako ibang brand

has anyone tried ferodo brake pads? by order kasi ito yun nag tanong ako sa nisway.

sa lahat ng nag post, salamat sa mga input. may pagasa pa pala maging peaceful sa loob ng auto.

Sir, try mo din pa-service ung mga piston ng disc brake mo. Sa katagalan kasi minsan nagco-corrode din ung mga yun causing abnormal sound while braking kasi hindi na maganda ung play. Usually ang ginagawa nila dyan is buffing then re-lubrication. Once na nagpa-service ka ng braking system mo dapat kasi kasama yun..

In my own experience only..

Thanks..

bakit pala hindi napansin nung mekaniko mo na glazed na ang rotor? dapat nakita na ito nung pina service mo nung una pa lang.

i think i know the culprit.. metal shims. yun maingay walang metal shims. meron kaya nabibilhan neto?

I have the same squeaking problem and would like to know if anyone has tried the silicone solution to silence the brake e.g. Disc Brake Quiet.
