Re: 2002 GMC Denali`
If the rotor surface is smooth, then NO, you do not have to turn them. If the rotor surface looks like someone has ran a heavy chisel around them, then YES. I have found that a lot of auto parts and repair shops are not turning rotors or drums anymore because the cost of replacing them with a NEW part, in some circumstances, is not that much more money. Do Yourself a favor and check out the price or a set of NEW rotors & pads at an auto parts store.
Personally, I rarely go to a dealership to get parts. I have found that most of the parts from a good auto parts store are just as good and sometimes better & cheaper than a dealer... BUT! that is my opinion.

Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
Remove the brake caliper and brake caliper bracket as an assembly and support with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
Remove the rotor retaining push nuts from the wheel studs, if applicable.
It may be necessary to strike the end of the hub or the rotor with a deadblow hammer to separate the rotor from the hub.
Remove the rotor by slowly fuming the rotor while pulling the rotor away from the axle.
Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the J42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.
Use the J42450-A to clean all rust and contaminants from the mating surface of the hub flange.
Use the J41013 to clean all rust and contaminants from the inside diameter of the hub section of the brake rotor to prevent any foreign material from getting between the brake rotor and the hub flange.
Install the rotor by slowly fuming the rotor while pushing the rotor towards the axle.
Install the caliper and the bracket as an assembly to the vehicle.
Perform the following procedure before installing the caliper bracket mounting bolts.
Remove all traces of the original adhesive patch.
Clean the threads of the bolt with brake parts cleaner or the equivalent and allow to dry.
Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488) to the threads of the bolt.
Notice: Refer to Fastener Notice in Service Precautions.
Install the caliper bracket mounting bolts.
For the 15 Series, tighten the brake caliper bracket mounting bolts to 175 Nm (129 ft. lbs.).
For the 25 series, tighten the brake caliper bracket mounting bolts to 300 Nm (221 ft. lbs.).
Install the tire and wheel assembly.
Lower the vehicle.
With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance.
Slowly release the brake pedal.
Wait 15 seconds, then repeat steps 9-10 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
Fill the master cylinder reservoir to the proper level with clean brake fluid.
You are going to have to pry it over the axle on one side of the park brake shoe assembly with either a pry bar or screwdriver. then just pop the new one back over the axle in the same way. Hope this helps
GM has an issue with dash clusters since 2002 and the company will not admit to it. We pay $250 each time to swap out the clusters. Let me know what city you are in and I will find you a company locally that replaces clusters.
I received your 3rd brake light flash controller-fully adjustable ez fit kit. installed on my 2002 gmc sierra, power coming into box, good ground and unit is not working. third brake light works good with kit removed. any help would be appreciated. thank you for your time.
hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk
