2002 Silverado shakes when I brake. Thought that it might be the rotors, had them turned. They were worn. Did not make a difference in the shake. Anyone know what it might would be? Also it is a Z71 w/ 110,000 miles. Thanks.

Check for scale build up between rotors and hubs. These mating sufaces must be clean and free of rust build up. While you're at it check for stiff and or worn out wheel hub bearings.

I checked all the bearings (turned the hub and felt for any tough areas) when I removed the rotors, they seemed fine. Didnt notice and rust or scale buildup. But I will check again. Thanks.

what kind of shape are the tires in? does it shake at highway speeds as well or only upon braking?

If the brake calipers/pads are binding this will occur....

also cutting of the worn rotors is not recommended...the thickness after many thousands of miles along with the internal corrosion makes cutting a waste of time/cash..

before installing new rotors make sure the caliper/pads slide easy,,,if they are binding [pads too large,caliper pins rusted,bad rusted contaminated caliper piston, etc,,,]fix this first..

did you check tie rod ends, up & lower ball joints, etc in front end? also is there abs felling when you apply brakes could be abs problem i believe you can remove abs fuse disabling abs so you can determine if problem or not. i like abs but not when it has problems. if this is problem please fix dont leave fuse out! remember when you press the brakes it stops the entire veh putting pressure on everything not just rotors.

Tires are new and in great shape. 275/70/16 i think. What ever the recommended tire size is. I rotors were turned once before so this is the 2nd time they were turned. The comp is not showing any ABS problems. I will check everything again. Would you recommend changing the pads? They are not worn out but I have owned the vehicle since dec 07 and have not changed them and I assume the are factory orginals.

my vehicle is 2000 sil 4X4,,,120,ooomi...original rotors never cut,,,still no brake vib's....

obviously you are not aware of these defective brakes ,,,and the problems I mentioned concerning bad caliper design and the issues of other brake componets...
since I am aware and take the extra time/effort to address these oem failures to make a quality brake system ,,I have been rewarded with rotors that are still not heat damaged..

there was a recent posting here where new pads needed to be filed so as to fit properly,,,its all china crap....

been there and done that several times...

I have a 03 1500 z71 with 88,000 miles and original brakes and pads and no problems whatsoever, also have a 03 2500hd with 135,000 miles and same thing. the brakes are still at about 85% and all the rotors are still in great shape.no these trucks are not babied. mine I use every week to haul water, and is a dailly driver as is my wifes. they also pull horse trailers, gravity wagons farm equipment, and other broken down cars. There are alot of these trucks here and I have not seen the bad brake design you speak of. My buddies and I have been getting very good service out of the brake design. I have even talked to people that said they have taken their cars and trucks to the dealer or shop because they figured it was about do for them and were surprised that they were still in good shape and plenty of miles left. that said there are cases where people abuse there brakes and I am not saying if you replced them already that you abuse them, they will wear out. I have seen people pulling trailers with no brake controlers and they say it stops just fine then cant figured out why they burn thru brakes or they ride the brake or wait to the last second then really lay on it. these all will destroy brakes quickly.

this is the first time I every heard of positive comments concerning these chevrolet trucks 1999- up with

no brake,,,problems,,,,obviously , I researched this back in 2001 only to find it was widespread.

my first failure was at 20,ooomi...pads seized, caliper pins rusted solid...I call that defective design...how does a vehicle owner abuse a vehicle to get that to happen ???

driving on roads treated with ice melt chemicals ???
GM shoulld have put that in the owners manual..

then later on these forums same issues with members having problems...

no problems with the other vehicles,,,,though...same operating environment...

I didnt say that all were abused. I didnt research it I live it, there are alot of these trucks here in northeast ohio and yes I have done alot of repairs for people, I live in the county in ohio (huron) with one of the largest uneployment rates and I do alot of repairs for free as people do not have alot of money and I have seen these brakes last along time, even on farm truck the are lasting. so I personally think that they are a good design and last.

I respect your opinion,,,just like I said this is the first time I ever heard someone say they had no brake problems with these vehicles thats all...

I guess its that dealership term "ABUSED THE BRAKES",,,as away of explaining why many have had issues...with this...

I have to service the brakes every 10,ooomi..to ensure that they will not sieze up on me...every tire rotation....it's a PITA....

You wrote "rotors" and you meant all four? Mine shook and it was the rear rotors. Had them turned at 72,000 miles and good as new. Fronts are still original pads and rotors at 78,000.

my 02 has 101,000 miles and is still on origional pads and rotors. this is michigan also where we deal with alot of crap on the roads that tend to rust and seize everything up. my 98 s-10 needed new pads once a year and new rotors every 2 or so. im very impressed with the brakes on this truck.

Check for bad u joints, my 96 shook very badly while braking and after I replaced the u joints the shaking quit. The u joints were in bad shape but didn't clunk much

maybe GM supplied the vehicles in OHIO/MICHIGAN with the platinum brake componets....

the metals used on my vehicle are poor/low quality..

I'm up to 161,000 on my original pads on my 2002 1500 4.8 Haven't touched the braking system yet.

I know I'm lucky to live in San Diego where rust isn't a concern.. but rush hour every day can't be avoided.

sounds like you have the rusting abs sensor problem. pull the abs sensor and clean the mating surface. next on the rotors you will need to clean all the rust and crud out of the groves that line up with the hole that the sensor goes in to.
