Just make sure the brake lines are not touching the body of the car when the wheels are on full lock, my back lines are a little long on the rear, was not an issue until I changed the standard springs to Eibach 30mm lowering springs. because the ride height was lower the brake lines was rubbing on the axle near the ABS cable.... so I used brake line grommets which work very well
the reason why your brakes are squeaking is because the fitter will not of used a little copper grease on the edges of the pads. it is nothing to worry about, just annoying.
