1997 Yukon Front Rotor warped

[yukonsteve]

Hi;
I'm new to this board, and while searching for old threads have failed to come up with any answers... so, My 1997 Yukon has 64K miles and I had a brake job done on it last July @ 60K miles. I use the vehicle mainly to back and forth to work (15mi each way) and occassionally tow an aluminium fishing boat (total boat/trailer about 2k lbs), I haven't used the boat much this summer and haven't don't any 'hard core offroading' . Anyhow, the front rotors were turned and the brake job was done by a mechanic that I've know for 25yrs and has been a mechanic on GM vehicles for 30yrs. The rotors were not thin, and he put standard DELCO Brake pads on it. So, should I upgrade to some other type of rotor/ pad combination. If so, which one? Should I turn these again and hope they don't warp again?
Some indepentant suggestions are welcome...
THanks in advance,

YukonSteve

Replace the rotors and calipers,and if you can the hoses.The thinner {turning} the rotors get,the quicker they warp. Remaned calipers are pretty cheap-a slight drag will cause the rotors to overheat and warp. Also-no offence to your mech.-a lot of guys push the piston in the caliper back without flushing the brake system. This will also cause probs.

Check the type of pads your mech. is using, if I'm not mistaken these are supposed to have "Ceramic " pads.
If you use ordinary composites you can ruin the rotors.

Just a thought. If you take the Yukon through a car wash right after coming in off the road and the disks are hat from use .... the wash & rince water will warp them fairly quickly. It happened to me on my 96. After I modified this practice I never had the problem again currently have 120K+ miles on it.

The water issue, like car washes, is a legitimate concern, but this can happen with rain and puddles as well. I had the same problem, and I took it back to the brake shop twice before they figured out that the rear brakes needed to be adjusted. The problem was that there was too much of the braking force on the front, and on a heavy vehicle like Yuk's, they will quickly heat up, and any water at all can cause warping. Have the rear checked and adjusted to force more of the braking power to the rear. It worked well for me.

Just a note for everyone to check out.

It is almost impossible to "warp" a brake rotor.
Check it out - It is very informative.

Warped rotors don't exist except in VERY rare cases. Myth busted!!

This forum (and this thread) is not necessarily where we want to discuss the finer points of crystalline brake structures and the transfer of material through high-heat molecular bonding, but the article goes on, ad nauseum, to prove a point that is, basically, unimportant. Now, I’m not one to burst anyone’s bubble, especially since there are so many more highly qualified people than I to discuss such matters, but the theory of the transfer of brake pad material to the surface of the rotor, or deposits, actually causing the “warp” of a rotor, and not the rotor itself, is a moot point. The rotor, for what ever reason, is out of spec, and warped, regardless of the causation. And I know by fact and experience, that rotors can and do warp (in a contemporary sense) b/c of quenching in water. And using widely available empirical data and common resolutions, such as the turning of the rotor or drum, solves the problem in most cases.

Whether or not a myth is busted here does not change the fact that rotors can and do warp – and a good turning by your local shop or mechanical professional will solve the problem.
