ABS kick after new pads instalation

Mr.BoZZo · 08-25-2012, 07:29 PM

Hi,

I need to know if anyone knows about this and if any have an answer...

I recently change the front and rear pads of my 2011 sport pkg 370Z for new Hawk HPS pads and a resurfacing of the discs, after the install of the pads the ABS starts to kick every time I brake. i changed the pads for the old ones and the problem has solved.

do you know why this is happend or anybody knows a solution?

thanks!

Well those hawk hps are made for the sports addition and unless you don't have the sport brakes then it fall under improper installations..

they have a lot more initial bite than the stock pads. Also, did you bed them in? 10 quick hard stops from 50 mph, then let them cool for 20 minutes and repeat.

Maybe your tires can't handle it?

Pero porque has pueso pastillas más putonas que las standar?? para que te frene más?? Yo he pasado mucho por frenos con mi 350 y te digo 2 cosas o cambias de frenos y calipers o usas la pastilla que le corresponde para librarte del dolor de cabeza.

El rectificar discos no es la solución, tampoco el asentarlos (500km) suavemente.

Esto me huele a cambio de BBK si quieres realmente resultados por lo que creo estás queriendo buscar...

Sorry guys but he understands spanish...

I ran HPS pads on the street for a while last year, and they work fine on this car. Are you sure ABS is engaging? Could you just be feeling pedal pulsation from a bad lathe job on the those rotors that left them with an uneven surface? (it happens). It's better to do rotors and pads separate (install and bed new pads on existing good rotors. install and bed new rotors with existing good pads), less variables to work with for sorting out problems, and the bedding process is easier in both cases, although when swapping pads you should try to scour the material from the old pads off of the old rotors first (lightly sand it off, I'd recommend ~180 grit garnet paper, and use a flex hone to score a pattern into whatever remains).

shouldnt be the rotors, he said when he installed the old pads back in, the problem went away. i think he said that lol

Eh who knows then, there's a thousand things it could be, hard to say without looking at it yourself

. An instructor at TDE once told me a story about her husband having a brake issue with his racecar on the track, and it turned out that he installed one of his brake pads backwards (metal backing plate facing the rotor). Even experienced, competent people make random mistakes

Yeah I thought it sounded pretty unrealistic when I first heard it, sitting in my car. But it has haunted me every time I put my brakes back together since. I find myself going back and double-checking the pad orientation before I put the wheels back on, and thinking to myself that I could easily make that mistake, too
