Front rotor suggestions

[swolanoli]

My 2000 Regal seemed to keep warping my 12" boneville rotors from advanced auto, I even switched to f-body calipers and stainless steel lines and the same issues. Can anyone suggest which rotors they use and where they got them? I don't do any emergency stops, just normal city/hwy mix.

Thanks in advance.

Sounds like you have an underlying problem then. Over torqued wheels being one of them. Rotors don't just warp from normal driving. Maybe you have a sticky caliper warping one rotor, or your rear rotors are dragging. I road race on cheap A-A rotors, I get them hot enough to turn colors and they stay relatively straight.

 

[swolanoli]

had the problem, got new calipers and barake lines, didnt go away. brand new fbody calipers and had the same problem after the rotors were cut.

do you drive with both feet? like resting our left foot on the brake pedal?

 

[swolanoli]

no I don't. i just don't want to replace them with standard rotors and see the same problem again. on a side note the brake pad clips that come for the pads, grind, and make noise. quite annoying, then I ground them down and they rattle. no good either way.

Check your tierods and your rear rotors.

rears are good I checked, tie rods are less than a year old. are you thinking an alignment issue?

You had to grind down the pad clips? I've never heard of doing that before, is it something with the F-body calipers?

they immediately started grindning and scrapping on the rotor the first day installed. after i grinded them down so it stopped, the began to rattle.

Damn. Could you bend the tabs at all to get them to secure on the caliper? I've never dealt with fbodies before so I'm not sure

idk I will have to get new clips and try again, I think I will just warranty the rotors at advanced auto and try again. the cheap Chinese steel they use never seems to hold up as well.

whatever it is you are not doing it right. the anti rattle clips should not touch the rotors. if they do then the caliper bracket is not lined up properly.

If you are using f-body/12mm bolts you need a bushing to take up the room between the bolt and the knuckle. Knuckle has hole for 14mm bolts if you use 12mm bolts you need a bushing.

Also, what are 12" bonneville rotors? Is it the same as f-body rotors?

rotors could be warping due to uneven torque applied to the lug nuts and incorrect torque sequence. do you use a torque wrench to tighten the lug nuts on the wheel?

Do we not have the BEST 3800 tech in the mother-fu*kin' world?! Yes, yes we do.

12mm bolts, everything came with the kit. I initially had 12in front rotor upgrade with brackets from a boneville. Yes f-body's use the exact same part#'s for front rotors as SSE-I Bonneville's. no issues for 6 years. I changed to the f-body calipers after the warping issue to eliminate the possibility of hung up calipers or the lines deteriorating inside.

to my knowledge everything is mounted fine.

Not working at a dealership anymore I have never used a torque wrench when tightening my lug nuts. It is the right way but never had any issues. I can try to torque them when installing the new rotors.

I tried putting the clips them in every possible way and they touched.

No TQ lug nuts?

 

[swolanoli]

No TQ lug nuts?

Nope tire iron. Tighten across, repeat on all in sequence.

"tight is tight" doesn't apply here! I always tighten them down by hand, but torque them to 100ft/lbs just in case.

Sears had a crazy sale on torque wrenches. the floating rotor requires even torque on the five lug nuts if they are not even = rotor warps.

anti rattle clips. where are they touching the rotors? The part going across the top or on the sides?

Bushings - can you describe the bushing i am talking about?

If you need pictures i can dig them up...

I have never used a torque wrench when tightening my lug nuts

would you use a torque wrench putting heads on a motor?

 

[Yaj Yak]

Nope.

 

[Yaj Yak]

I have never once used a torque wrench putting lug nuts on

just set the impact to kill and hammer her home.

Yeah... my rotors warped shortly after I had the car to a shop... they snugged the hell out of my lugs. Need to warranty them! In other news, I've also got F-Body brakes... and you have to be careful putting them on. You CAN get it right and not have scraping on the hardware. I typically run a zip strip or something through the opening on the back of the caliper and use it to hold the clip in place as I slide the caliper on. Hope that made sense!

Make sure the wheel bearing mounting bolts are tight and also that the bearing have no excess play. The axle nut should be torqued to 180ftlbs as well.
