What's up with these rotors

[98hoe]

So I replaced my rotors pads and calipers last month do to vibrations when I use my brakes. The problem was corrected for a few weeks but I notice that the vibrations are starting to come back. I have not towed anything or beat on my brakes. Are the stock rotors just too small. Has anyone experianced this problem? I really don't know what to do next. I don't want to keep changing the rotors every other month. P

Do you do a lot of braking? It doesn't have to be heavy braking, just a lot of city driving will heat brake rotors up really quick and when they are heated up and come in contact with cold water they will/can warp. You can get hot rotors wet with cold water just by going through a car wash or washing the car yourself and hitting the rotors with the cold water coming from the garden hose. this is two ways to warp rotors.

If you think this may be the case, then change the rotors once again and next time you wash the hoe, let the brakes cool down or do it first thing in the morning before you hit the road.

Either way, if the rotors are indeed ruined again I would at least pursue some sort of exchange for new ones under the manufacturer's warranty. Problems within one month are unacceptable.

I'M not sure, but I would think that the manufacture would not warranty this as they would deem it damaged from the customer.

Motorcycle motors are all aluminum and heat up at a drop of the dime. If you were to run a motorcycle around the block a few time, come home and wash it right away you would crack the housing on the motor and the manufacture would not cover it. It clearly states in bold print in the owners manual of all motorcycles not to wash the motorcycle with a warm/hot engine. It says wash it first thing before starting it up are after the motor has cooled after a ride.

How many miles are on the truck?

I have vibrations when braking at ~60 mph. The Tahoe has ~16k miles, no towing, easy on the brakes, and do not wash when the rotors are hot (had that problem with another vehicle). In any case, I will have the dealer look at it next oil change and I will update.

If the dealer does not take care of it, I will look into better aftermarket rotors like Stoptech (not sure if they make one for the Tahoe yet). I would like slotted and vented rotors...

Do you properly torque your lug nuts (with a torque wrench) anytime you put your wheels back on?

I had MAJOR rotor warping problems on a previous vehicle (went through a few pairs within a month or two, the parts guys replaced them twice under warranty!). On the last pair I avoided rapid cooling of the rotors (water) AND, I torqued all the lug nuts to the same amount. I have not had another warping rotor problem with that vehicle or any other vehicle since I've started to properly torque the lug nuts.

Rain drops are not cold enough and not forceful enough to cause damage.

If it were winter and raining I would assume that you wouldn't be riding your bike in it.

A steady stream of cold water will warp/crack aluminum motors and steel rotors.

Take your garden hose and turn it on, the water will come out semi cold then after a minute it will be cold. Let the water run from the hose for ten minutes and check the water again, bet it's even colder.

Remember when most people wash there car, they wash the rims and tires last making the coldest water hit the rotors.
