safer to buy new drums and pads , or whole new hub. if rear brakes aint working proper.
i bought brand new rear hub set 2 years back with drums included and had grt brakes for what ppl complain about corolla in Pk, and car was driven by many members at PW who know what i am talking about when it comes to rear brakedrums.
obvoiusly u keep in mind limits of yr road condition when you talk brakes in PK, roads are gone slippery everywhere traffic is in excess..
but if some show off issue with rear disc,, then Must have brakes checked before installation, because pistons in brakes can get locked.
