Clunk noise when breaking

I noticed a few days ago when I apply my breaks there is a kind of clunking noise. It only does it once when I apply the breaks, same thing in forward or reverse. Breaks seem to work fine as well as everything else.

 

You have a clunk when you apply the BRAKES. You drink coffee on BREAKS.

 

have u replaced pads lately

 

Your front pads have a little play where they fit in your calipers. When you switch directions, that first push of the brake pedal lets the pads move a little and 'seat' toward the leading or trailing space in the calipers. Some refer to this a brake pad slap. If it's this, it's normal on these trucks.
It's more of a 'clack' noise than a 'clunk' in my opinion. This may be what you're hearing.

 

I second that motion . . .

 

You say clunk he says clack I say click.
Worn brake parts as mentioned.
My click went away after new pads.

 

Yeah it is more like a clack noise.

 

I’ll look into that, thanks.

 

No not since I bough it a year ago

 

X 2 . I have the same issue. It took me a while to figure it out but I found it to be this ^^^ Just one more thing that is a normal on this trucks.

 

Correct this is common on these trucks. Spring is worn out, they cost about $2 a side at O'Reilly. There is only one per side from the factory, you can add a second one if you want.

Pull the pads, put some fresh grease on the back side of them, install new springs. Done

 

Just an idea.
It's a 2015 so how many miles on it as rears seldom wear much. So are you backing up and putting the brakes on daily as self adjusters need you to racket the adjuster and move the shoes out that keep them tighter to drums.

 

Just to cover all the possibility, strange noises that happen while applying the brakes can also hint at loose or damaged parts. For example, a broken leaf or loose u-bolts on the rear axle could cause sounds when braking.
Which of course is not to say that there is anything broken! Just be sure to figure out what exactly is causing the sound, and inspect all major components, in order to make sure that doom isn't waiting for you in the middle of the next intersection.
