This is a quality product that installs with almost no problems. The rear hoses fit either side like they were made for left and right, although they weren't marked as such. The front hoses were labeled driver and passenger side, but they were mislabeled. It's easy to tell which brace fits which side, so it's not a problem. The feel of the brake pedal after pumping the booster is much firmer and the modulation of the brakes is much better.
