ako kapapalit ko lang ng master cylinder. so far hindi naman nagstick ang front or rear brakes after 10 hrs (about 300+ kms) straight run. walang patayan ng makina.

sinunod ko lang yung specs with regards to brake pedal free play at yung clearance between pushrod and primary piston. i suspect nagkakaroon ng interference due to parts getting hot (expanding parts or brake fluid) between the pushrod and primary piston...ideally zero ang clearance. kung may interference, dragging brakes dahil covered na yung compensating port ng master cylinder. i dont see that the repair kits can affect the clearance. yung pushrod adjustment at pedal freeplay ang magaaffect neto.

with regards to front disc, maari din na nawala na yung elasticity ng rubber seals ng caliper preventing the piston to retract thus dragging the pads on the discs. in turn, pinapaiinit din nya yung brake fluid up to the master cylinder. possibly expanding the primary piston (or reducing the cavity on the primary piston where the pushrod resides) making the two contact each other (pushrod pushing primary piston without any pedal application).
