Hawk pads

i had a shop install front and rear carbon Hawk pads
they cut down the rotors correctly they said
i did not know about a break in process "listed below in PDF" and my shop did not mention it to me.

needless to say my brakes feel like mush!
the brake pedal goes all the way down basically to stop the truck

are these pads Ruined? or is there something i can do to get them to work properly or do i scrap and start fresh

my shop was no help today as they put me on hold and i said i would call back later after i discussed this matter with my team aka u guys
lmk
thanks
guys

Re: Hawk pads

If your brake pedal is going all the way down I'd guess that they opened the brake system and did not bleed the brakes afterward. Perhaps they compressed the calipers, pushing some fluid out of the master cylinder and then failed to refill the fluid before pumping the brakes. Just a thought.

Sounds to me like there is air in the system somewhere.

Re: Hawk pads

Definitely air in the brake lines, I had the same problem after they replaced my ABS pump and control module under warranty.

The air sound is normal. It's just your vacuum booster. If you're getting an unusual amount of brake pedal travel it's probably air in the hydraulic lines. Air in the lines will compress thus the additional pedal travel. Fluid will not compress so the pedal travel will be much less. Take it back in and have them fix it. It's a major safety issue. Just swapping pads should not have change the braking performance that much.

Re: Hawk pads

Well after a number of different possible issues my guys resurface the rotors and everything works great
Mission accomplished with no brake dust
I would just chalk it up to very busy tire store three deep in each bay trying to make as much money as possible and putting the quality work second I'll have to take a look at that

How do I know the work was sloppy I got my wheels back when I changed my tires there a few weeks back and they left the tape for the wheel weights still on the car big had big white patches of tape I said to the manager I'm a car guy I care how my car looks it looks worse now than when I brought it in why would I continue to bring it here he immediately had the wheels cleaned the weights put back onevenly and done precisely

Amen to knowing how to talk to people in life
Comes in handy
Thanks guys

Re: Hawk pads

Now to out and bed the pads in or youll have sqealing. Do three runs up to 60 mph andnthen brake moderately hard down to about 5-10 mph without stopping. Then drive for a bit to let the brakes cool. This will bed the pads and form a glaze.

Will do
I did this after initial install.
No sqealing but had that vibration
Resurfacing the rotors too care of that.
Now I'll bed them again as I feel there still just average and need a proper break in to get the proper feel and performance.
By the way the guy from hawk wrote this to me as I though because I did not properly break them in on initial installation I had damaged them.
Here's his response.
Cheers

Hi Rob,

Don’t worry. You have not ruined the pads at all. The pads will not achieve their best braking power until they get hot enough to homologate the resins within the pad material. I have end-users who will tell me that their pads are not working after a month (1,000 miles) of driving on them. They send me pictures of the pads where I can clearly tell the pads have experienced any heat. I tell them to bed them in again and get them hot. You should be able to smell the binders and may even see some smoke. They call me back and say these are the best brakes I ever had.


Best regards,

Is there a noticeable reduction in the amount of brake dust that accumulates on the wheels with the Hawk pads? I'd like to be able to go around the block without having to re-clean my wheels. I've only got 2k on the stock pads and the brake dust is killing me. Do the stock pads improve with age?
