ive a 01 b4 legacy,the other day as i was braking i could hear a very rough grinding sound coming from my front drivers side brake,then i got this horrible burning smell.i got out to check and the caliper was smoking hot,the pads are only 3 months old,i got back in car and took for a spin and done a bit of heavy braking and it got rid of the grinding...that was 4 days ago and now today im getting the same issue...would my caliper be fucked of maby one of the pistons are ceased and a bit of copper grease would sort it out???bringin it to mechanic after dinner,he reackons one of the pistons is starting to cease!!im hoping its a quick fix and wont need another caliper...
