Brake squeal

Hi everyone

this is what happened to me today. i was driving along a main rd @ 60kmh and some f*cker changed lanes with no notice (i honked the guy swore back, not the point). i slammed my brakes, they locked and thankfully no collision else it'd be my fault.

So now my park brake is stiff/tense. Also, my rear brakes (pads changed saturday) are making a light rubbing/screeching noise whilst driving. any suggestions on a remedy? i have a feeling i need to push my caliper piston back?

Cheers in advance

it maybe that the pads are still new and hasnt broken in properly. happened to mine when i had new pads.. it disappeared a week later..

problem solved.
cheers man
