Reverse ticking noise

[Dirtautoguy]

My 96 chevy Cheyenne has been doing some rather odd things lately.

 

If I put it in reverse and hold the brake there is a ticking noise it's pretty quiet but it's there coming from down and to the left if your sitting in the driver seat.

 

2. Sometimes if I barely push the brake pedal it sounds almost like there is slop in the disk brakes or in the master cylinder or something( the master cylinder and brake pads are new)

 

3. On both of the front tires if I spin them forwards they don't make much noise but if I spin them backwards the click both the hubs are new and I think the driver side cv joint is too.

 

Could it all be related?
