I just got new wheel bearings and brakes for my car. Now I feel that it has lost a bit of power. I suspect the new brakes might be in contact with the disc.
So I roll my car in neutral at about 2km/hr and the car stopped soon after with slight braking effect. This further proves it. Is this normal for new brakes or the mechanic just suck.
go get it checked. i believe your brakes haven't been installed properly. go get a 2nd opinion too.
