I have changed the front discs Original for RM265 (USD70) ea. and the rear discs OEM for RM95 (USD25) ea. with 4 sets of original brake pads [Front: RM185 (USD49); Rear: RM120 (USD32)].
They ran out of brake pad paste but I didnt notice any squeaking when applying brakes.
However, I did notice (at first) some hissing when I pressed the brake pedal when stationary, but eventually the noise just kinda "disappeared" when driving.
Braking wise - I think its a little better than before though it could just be pyschologically-felt.
The total cost, including labour and bleeding of brake fluid & change of brake wires: apprx. RM1,217 (USD320).
126 tailed by a 203, 129 leading the pack.
