Brother first check from Mechanic or suspension guy that brake pads and disc are in shape or not.
Is your brake pedal play normal or it goes to the floor ?
Brake fluid level, last changed date ?
2003 Accord Nissin brake pads front 11,300 rear 7,900.
MK brake pads front 8,000 rear 4,200.
Importer's rate only almighty Allah knows what 3S dealer will charge you.
Also use genuine Honda heavy Duty DOT3 brake fluid in read & white bottle do not poor good old sikken.
Let me know if you cant find them.
