i have a 06 crew with 700 miles on it. yesterday after putting on a set of 24's i drove it around town for about 25 miles with no issues. i started home on the highway and had to stop and experienced a shake under braking. the brake pedal seems to pulsate very bad. i got out and looked over the truck and noticed a brake smell in the rear. the drums were extremely hot in the rear. these wheels were on my denali with over 15k drove on them with no issues. the denali has disk brakes on it but i have never heard of the crazy idea of the wheels causing this. i have read a few posts about another issue a guy was having but mine seems more severe. the shake is extremly bad like the rears are locking and realeasing in the rear causing wheel hop. it just makes no since that there are a ton of people with lifted trucks with large tires that basically is the same deal and they have had no issues. the dealer has it now looking at it. is there any one else with the same issue?

 

simply because you put 24"s on it that is a lot of rolling mass to try and slow down! you'll definately want to upgrade your stock disks to some larger diameter rotors and put some disks on the rear as well. I put 22's on my 03 extended cab with 4 wheel disk brakes and I noticed a significant degrease in stopping distance and it is only worse with 24's. Not sure what would cause it to hop though

 

take off the rear wheels and looks for little ratainers holding on the brake drum. take them off! they are just there to hold it from the factory, but it makes them shake pretty bad

 

Makes sense and you should get charged for it,unless it was the dealer that installed the wheels

 

Hell yea! Mine shook like a bitch when i put my 22's until someone on here tolf me to take the little clip retainer things off and then it was fine.

 

the retaining clips were removed when i installed the wheels....

 

No idea then but there is probably a big difference between my billet 22's and your chrome 24's. Im sure they are much heavier so maybe you warped your brakes?

 

Are you saying there is a problem with your truck?

 

the dealership said yesterday that there is very strong brake pulsation. they were going to try and look at it further today. everyone keeps saying the the weight of the larger 24's is causing it. what about all of the people (including me) that has lifted a newer style truck to put on a set of 35-38" tires on them. my yukon that i lifted with 35" never had this issue with its drum brakes. i would bet that the weight of a 35" tire and wheel to be about the same or heavier than my current combination. the wheels weigh 43lbs ea. and the tires are 50lbs. ea. i just cant believe that this makes my brakes pulsate. i can understand longer stopping distances due to the added weight(just like towing)
