salam all, this weekend i took m cultus for its 20k maintenance, this time i took it to local workshop instead of suzuki 3s, as i dnt trust on them.
tunning was fine so i started by changing the spark plug with 4point bosch, these are really good have tried them on my city and another cultus.
next i want my brakes' service, i had in my mind that i would need to change the pads, but after he opened the assembly he told me that the disc has lost its shape for which he will put the disc through the rubbing machine.... i notice the pads are worn out irregularly, see pics below, more from one side.
my question is that, what could be the reason for that irregularity, the mechanic was of the point that it happens normally, and he couldnt give me a valid reason.
can any body point me what could be the reason for it. and ya one more thing after this service, i notice that applying brakes on high speed gives a vibration sort of feel on the pedal :-s, please suggest what should i do to stop this from happening again.
btw if some one would be interested heres the total kharcha for 20k maintenance
spark plug 1400
engine oil (shell) 1700
air filter 260

brakes pad 1250
