The rotors on a Chevy Tahoe are an essential component of the braking system, since they’re the part that the caliper and pads clamp when the brakes are applied. Depending on the model of Tahoe, it may have four-wheel disc brakes or just front disc brakes. Though rotors are designed to last much longer than items such as brake pads, rotors should be inspected regularly for wear and replaced if necessary.

Step 1

Loosen the lug nuts on the wheels with a tire iron. Lift the Tahoe with a heavy-duty jack and place the vehicle securely on jack stands. If your model has only front discs, then support just the front. If it has discs at all four corners, support it at all four corners and remove the wheels.

Step 2

Spray brake cleaner on all of the brake components and wipe them off with a clean rag. Remove the caliper bolts with a socket or a wrench. The bolts are located behind the rotor at the top and the bottom of the caliper. You may need a breaker bar to loosen the bolts.

Step 3

Slide the caliper off of the rotor. It will still be attached to the soft brake line, so support the caliper on something or tie it to a nearby suspension piece so there is no weight on the brake line, which could potentially damage the line.

Step 4

Remove the two bolts for the caliper bracket. Set the bracket aside.

Step 5

Pull the rotor straight off the hub. It may be frozen on from rust and dirt. If this is the case, then spray some type of penetrating oil where the rotor meets the hub. Let the fluid soak in and then tap the rotor off with a mallet.

Step 6

Spray brake fluid on the rotor mounting surface and with a clean, dry rag, clean off any rust, dirt and oil.

Step 7

Spray brake fluid on the front and back of the new rotor and wipe it down with a clean rag. Slide the new rotor into place.

Step 8

Reattach the caliper mounting bracket with the two bolts. Slide the caliper over the rotor and insert the caliper bolts. Tighten the caliper bolts to 110 ft-lb with a torque wrench.

Step 9

Replace the wheels and lower the Tahoe back to the ground.
