Router,

I had the same experience before. Iba naman yung katatok ng CV joint, iba naman yung sa brake eh, u can identify the difference.

In my case, maluwag yung brake pad hole ng DISC brake ko sa unahan (moving part kase yun or tawag dun eh Floating caliper) where you put the pad (pinapasok mo kase iyun sa parang ROD guide or Pad-Retaining Pin and it just hangs there). So when a brake pedal is half pressed (or actually slight pressed lang) eh the DISC tends to move the pad a bit, tatama ngayon sa pinaka guide niya. It produces a sound, na akala mo delikado when you are driving the car or hearing it from the inside, pero actually eh play lang yun nung maluwag na DISC Brake. My mechanic never found out what the problem was, ako lang naka discover nito, ginawa ko eh I let someone drive the car very slowly and half press the pedal habang pinakikingan ko yun mga gulong to find which part was making that sound. After finding that out, nilagyan ko lang ng some sort of a sim, pinalibot ko dun sa pin to become a bushing , I cut out from a copper film sheets, para lang wala siyang play.

Yung experience mo ba eh kapag lower speed ka lang? Check mo na din yun caliper assembly mismo, kase baka yun ang maluwag eh, hindi ko kase matandaan exactly yun nangyari sa akain matagal na kase yun ten years na ata. Pero I am definite its the DISC BRAKE Assmebly lang and it was very to fix.
