Clunking after brake job

What is your question?

My boyfriend (who is a mechanic) did a complete brake job on my 2007 Honda Pilot. Immediately following it started making what I would call a clunking or banging while braking. He thinks it may be bad motor mounts and is ordering parts but after reading some online I’m not sure. Although it does have more bounce than it used to and the motor does rock a fair amount when revving or braking. But it only makes the noise when braking. It does not when braking in reverse though. The braking feels smooth enough and there is no vibration in the peddle. Just a horrible, rhythmic thud. Does not matter the speed, it’s anytime the brake is pressed. Before all this there was a faint thump when going over a bump but no other sounds. My boyfriend took the brakes apart and made sure everything was in there right, etc. But couldn’t find anything wrong with the pads, rotors or calipers. Other info: it is only in the front and seems to be coming more from the passenger side. Thanks!

What makes this problem better or worse?

It’s every time braking

How long has your 2007 Honda Pilot had this problem?
