4 pots
 

on drive to work + way home my osf caliper appears to be braking more than other side , the disc is much hotter than other side + much more brake dust on wheel , they were refurbed before i got them january and Tone has pushed pistons in and out , do they need another refurb or is this a common problem , nsf works perfect , car is a 95 wrx. chris. :sadno:

if all of the pistons work perfectly then it could be a sticking pad or poss a wheel bearing going??
