Hawk HPS Pads, Partial contact?

[illeztimportz]

Hey everyone I have a question regarding the Hawk HPS pads I purchased not too long ago. They do not make full contact with the whole rotor. The most outer edge is not getting any kind of contact. Is this normal with these pads?

noone? anyone? (uhm)

Did you follow the bedding procedure for them? Any noticeable difference in brake performance?

 

[illeztimportz]

it didnt come with any procedure..? ...i did kind of have a hard time getting the clips into the caliper though...

Did you happen to grease all the contact points when you re-assembled them?

hey i got the same problem can u hit me up and let me know how u resolved it.

i have the same pads.

guys that is normal. after gradual OR one-shot bedding it slightly rubs down, but it wont go completely flush until a good few thousand miles. They are engineered this way for two reasons i believe...

first to ensure that over time, they WILL get bedded properly if the initial bedding went wrong.
second, i dont know. lol Anyone wall call em to ask?

put it this way, i used em on the track a week after install and gradual bedding, and they performed damn near flawlessly. i wouldnt worry about street performance...

EDIT: this is all provided everything was installed correctly, the caliper guide bolts are torqued down well, the pad clips are properly seated and the back of the bads are flush to the caliper housing/piston, the brake fluid is properly filled/bled/and pumped pre-use, the rotors were properly torqued and flush to the hub, all lines firmly connected...

Alright thanks man. Ill just let it b for now.

Maybe it's the rotors as opposed to the brake pads?

I have the opposite problem, my pads do not fully extend to cover the inner part of the rotor - i.e. towards the center. So there is a ring of rust around it.

 

[batou079]

errr... ydrone. you mean the pads are simply not wide enough to cover the rotor surface?
or it has a diagnal slant to it where only the outside of the pad touches the rotor?

if its the case of the second scenario, thats normal.
the ring of rust is no doubt residue from elsewhere getting on the rotor and being pushed down by the pad. Like rust from the calipers or rotor hats....

 

[batou079]

its definitly not the rotors, those have to run perfectly parralel inside the calipers otherwise your car would shake like CRAZY and you'd cause some major dmg... non straight rotors would be warped or cracked and would be VERY obvious when driving.

I have them on mine with Power Slot rotors and once they were broke in the stopping was dramatically increased.
