When i step on the brakes, they make a noise like a machine gun.

You need to be a bit of a detective for this. Is it one or two rattles then it stops or a constant ' machine gun' rattle sound. Is the noise there when the vehicle is standing at idle, only when moving or both? Does road speed alter the sound? Does the noise change if you stop and Rev the engine? Does cornering affect the noise? Use the comment button below and I'll see what extra help I can give you.

For safety reasons please have the brakes inspected as soon as possible. Honestly there is more cause for creaking and may or may not have been there before the repairs. I am a full-time mechanic and from time to time have a customer complaint about a noise that wasn't there before the work was performed. Don't get me wrong though, you may be right. If you are then it may be bolts or nuts that was not properly torqued, a surface that wasn't properly cleaned before reassembly or human error. The technician may have missed something or for a necessary step. A faulty caliper with piston issues, a caliper mounting bracket with damaged sliders and or improperly cleaned surfaces where the shims and brake pads slide could all be suspect. The pistons, sliders and brake pads should all move and slide freely, without play. The mechanic may test drive the vehicle to confirm your complaint, inspect all the brake components located behind the wheels and report their findings. If nothing is found they will need to look elsewhere. Hope this helps. Please let me know if there is anything else. Good luck.

Could you give me a more detailed description of what kind of noise it is? Is it a bang like a gun? A thump or 'clonk'? Or a machine gun like rattle? Is it as you turn the key or after the car has started? These details can help work out where the problem is.

No

How would we do that ?

How does one guess at noises over the internet ?

It sounds like a relay. You need to hunt it down!

The lock that is doing the machine gun action has a bad actuator. You will need to have that lock replaced.

either brakes are dragging or you have a wheel bearing going out. most likely if it is significant noise it is the bearing, simply to replace if you have an impact gun.

they prob just looked at the outter pads ,the inter pads will ware out first thats where the pressure is applied , you need too pull the callipaliars too check them!!

Hi there,
when the noise is heard, try putting very slight pressure on the brake pedal and see if the noise goes away. If this is the case then definitely the brakes have to be removed and checked again. But if the noise is still present then it's something else doing that noise ans further investigations needs to be carried oput.
Cheers

have the brakes looked at at your nearesr honda dealer or reputable repair shop. sounds like ur brake pad sensor is contacting ur rotor...
