car still 'bucking' after new pads and rotors... ?
i had Rotoworks drilled/slotted rotors from WS6store.com and Hawk HPS pads installed yesterday and the car is still 'bucking' back and forth slightly... it's not as bad as before, but it's still noticable. any ideas?
thanks
Ron

the car comes to a rough stop when braking still. it bounces forward, opposed to coming to a smooth stop is the best way i could describe it and the steering wheel shakes a ton...
just had an alignment and the brakes done

I know what you mean, my TA does that too. Its like the brakes grab then let go for a split second then grab again and keep doing that till you stop, creating that bucking effect. It only seems to happen from speeds of around 45 and under. If you brake at higher speeds its smooth till you hit about that mph range. Anyone got any ideas?

mine was unbearable with the worn out stock brakes, but it still does it slightly with the new ones.

Have you changed your rear pads? I had the same problem and thought that I had warped rotors. I bought a set of used front rotors off ebay, put them on, no change. So I thought that maybe I got screwed and went to autozone and bought a new set. Still no change. I then went to the rear and changed the pads, voila, problem went away. Just a thought.

Not much left unless you have a f@cked up line-lock installed...

Hmmm, interesting thread. I have been researching this topic lately because I have been having the same problem that Silver02TA mentioned. I think I may try bleeding the lines this weekend.

Did you get zinc coated rotors? If so, you might be in the middle of wearing the zinc coating off. As the coating wears off, there will be a difference in friction between the coated sections and the uncoated sections. That could be your problem (if you got zinc coated rotors, if not, disregard this post).

Just FYI, if there is any debris or rust behind the rotor as it mounts to the hub, it will act exactly like a warped rotor. The rotor will not run true like its supposed to if it does not sit exactly true to the hub. Just for comparison at my shop when we got our new on car brake lathe, we put a small piece of paper behind the rotor and retested runout- was at .010"!...and that was only a thin piece of normal paper.
