Default DBA 4000 front rotors and hawk hps pads smoking?

ok so I did my front rotors and pads today, DBA 4000 slotted and hawk hps pads. I cleand the rotors with alcohol, wiped them down. I followed the Hawk instructions for bedding them in but the pads started smoking like crazy. Is this normal? I have to do threars tomorrow or monday and was wondering if this will happen again or did I do something wrong.

when you said you followed hawk's instructions, what exactly did you do? stock WRX callipers or aftermarket callipers? is this your 1st time replacing rotors and/or pads?

yes first time replacing rotors and pads. I did 10 stops from 30-35 med pressure and 3 hard stops from 45. I am also using TIC titanium shims insted of the slotted stock ones but am using the stock anti squeal shims that go facing the pistons.

so the only shims I need are the Ti TIC shims or do I need those slotted ones also? I also have to do the rears same setup but no TIC Ti shims. What shims do I reuse for the rear the stock slotted ones and get rid of thoes half shims that are supposed to be anti squeal shims?


thanks everyone

I was just worried abou heat transfer to the caliper and destroying the seals. Also over heating the fluid. I am switching over the stainless brakelines and Motul 660 fluid when I am done.
For the rears when they are broken in I should still not use any shims, even the slotted ones?
thanks for the help. I will also be doing struts and springs soon with groupn tophats.

same here. anyway, some of the pads already come with shims which are permanently fixed to back of the pads so no point adding extra shims

what's wrong with that I figure the high boiling point of the 660 and the ss lines I should not have a problem with the fluid getting too hot, and it will decrease brake fade. I also would like to get into non contact road racing.

Scotty I took all the front shims out and did the rears today with no shims. The question is would the front pads be ruined? They have a small lip near the outer edge of the pad. I sprayed them down with brake cleaner and scuffed them up to take the glazing off. Do you think they will be fine?

Are you sure there is no another metal plate stamped to the back of the pad? Looks similar to this.



RBF 660, are you looking in to some serious racing? I have ATE which is less than Motul RBF 600 and so far 30min at the race track with race pads braking from 140mph and 80-90F outside temp. I have no problem boiling fluid. So it is just wasting your money and if you think you will be faster than me then those brakes will not save you and you need to look for BBK. Also before that fluid will see any high temperature your HPS pads will vaporize. It’s just a bad combo, super high racing fluid and street pads.

you say they have a lip. as in the pad is hanging over the outer edge of the rotor? scuffing the pad should be just fine. one thing you should do is drop by any auto parts store and pick up some synthetic brake grease. put a nice thin layer on the back of the pad. doing this some what adhearse the pad to the caliper and pistons so the pad pulls off the rotor.

also, new rotors and pads do have a habit of smoking a bit after the first "hard" run, its impossible to get new rotors 100% clean and dry before install, it happens. however i have noticed some companies have some fairly aggressive bed in procedures. a few semi brisk stops from 30mph with moderate brake pedal has always worked for me. but if they smoke on normal driving thats no good.

I had HPS pads on my 99 neon rt and on my 98 prelude, they both had shims on them. The WRX 06-07 pads don't have shims on the fronts or rears. Fronts are 4 piston and the rears are 2 piston. That's why I found it weird to use no shims at all
