Hi guys.

I need ur recommendations.

Currently im using rear disc for my kelisa.

Last week im going to puspakom for inspection (need to do detaila inspection due to my roadtax expired more than 1 year),

And, my kelisa fail at brake test.

My question is, how to improve the braking power for rear disc klisa?
Another issue is regarding parking brake. Need to exceed certain %. How to improve parking brake?

My plan, take out the cable and do the cleaning, sevicing the caliper and piston & changing to a new pad.

Is there anyone here upgrading the brake servo ?
Someone said that, by installing rear disc, the pressure from current servo is insufficient, thus resulting weak pressure to these 4 wheel. Izit true?

Any idea how to rectify such issue?
