How to Replace the Rotor in a Chevy Avalanche

Trustworthy brakes are important, especially on large vehicles like the Chevy Avalanche. Rotors don't need to be replaced often, but if they become warped or worn down then it's time to swap them out for new. A good option for the mechanically inclined is to do the job yourself and save money on the labor.

Instructions

1

Purchase new rotors at your local auto parts store for your Chevy Avalanche. Replace the front or rear set of rotors at the same time to keep things even, or replace all four at once to maximize braking performance.

2

Siphon about two-thirds of the brake fluid from the master cylinder before replacing the rotors on your Chevy avalanche.

3

Get your Avalanche off the ground by using jacks and jack stands to support it. Block the rear or front wheels to prevent it from rolling while you work.

4

Remove first tire and wheel assembly. Use the tire iron provided with your vehicle to remove the lug nuts from the outer wheel, or a socket or air ratchet.

5

Move the caliper out of the way. The caliper is held in place by two bolts. You can release them using a C-Clamp to push the pistons on the caliper to give enough clearance to slide it off. Suspend the caliper with mechanic's wire to avoid disconnecting the brake line.

6

Take off the star washers holding the rotor in place. Chevy Avalanche rotors are held on by press-on star washers that you can either remove or cut off (unless it is an older model in which case the rotor is held by a screw). Remove the old rotor and set it aside.

7

Install the new rotor, replace the screw or star washer, then replace the caliper, caliper mounting bolts, and finally the wheel assembly and tire.

8

Repeat these steps for each set of rotors. When you're done, lower the vehicle, tighten and torque the lug nuts, then add new brake fluid. Pump the brakes until you get a firm pedal and test drive your Chevy Avalanche to make sure that the rotors are working properly.
