Hey guys, I've got the base brakes and the cars at 25,000 kms and for the last few months I here squeals everytime I do a slow stop and on the highway too at any speed when braking to slow down. Had a mechanic check it out months ago, said I had plenty of pad, enough for years and showed me, they grinded the pad on the sides or something and the squeal went away for about a few weeks, I can't exactly recall. Told them the squeal came back and they said it was normal.. it's not normal bc every car on the road would squeal and it didn't squeal the first 25,000 kms from new.. summers coming up and I can't drive like this, it's really taking the enjoyment out, I can't stand it. Any suggestions would be appreciated, thanks in advance.
