Q: Does the new rear engine mount needs time to settle in? on 2007 Honda Accord

I had the rear engine mount replaced as the car was making noise in revere gear. But it now is making worse noises in reverse and brakes both. THe mechanic said it will take time to settle the new mount.
How much time does it take? Should I check it with some other shop? It has become worse than before.

Replace all the mounts not just one. If your mechanic installed the rear mount correctly there is no such thing as "settling the mount".
