What is the method for replacing the rear brake pads on the Envision?

Remove the rear brake drum. After taking off the tire, the brake drum will be visible. Use a hammer to tap the surface of the brake drum to loosen it, then remove it. Remove the return spring. Insert a flat-head screwdriver into the gap of the spring and pry upwards with force to remove the return spring. Detailed steps are as follows: 1. Remove the fixing screws: Use pliers to remove the screws that secure the brake pads. Each wheel has two brake pads (front and rear) and two fixing screws. 2. Remove the front and rear brake pads: After completing the above steps, the brake pads will automatically detach from the brake assembly. Simply remove the brake pads, but be careful not to lose small components on the brake pads, such as the self-adjusting mechanism. 3. Install the new brake pads: Remove the locating pins from the old brake pads and install them on the new brake pads. Once both sides are assembled, they can be mounted onto the brake assembly. Alternatively, the front and rear brake pads can be installed separately in sequence. 4. Adjust the handbrake height: After installing the brake pads, adjust the handbrake height. Use a flat-head screwdriver to pull the ratchet of the self-adjusting mechanism outward, which will lower the handbrake and improve braking effectiveness. However, avoid over-tightening. When testing with the new brake drum, slight resistance should be felt. 5. Install the brake drum: After ensuring the brake pads are correctly installed, mount the new brake drum and reinstall the tire.
I just replaced the rear brake pads on my Buick Envision. It's not a difficult job, but safety is crucial. First, park on level ground, engage the parking brake, and loosen the rear wheel bolts. Then, use a jack to lift the car slightly and place jack stands to ensure the vehicle is stable. After removing the tire, you'll see the brake caliper. Loosen the mounting bolts and hang the caliper to prevent it from dangling. The old brake pads come off easily, but be careful not to let dust fly everywhere. Clean thoroughly and check if the brake disc is smooth. When installing new pads, you might need a special tool to retract the piston (rear brakes have electronic parking, so be careful not to force it). Then, install the new pads and apply some high-temperature lubricant to the caliper pins. After reassembling everything, test the brakes at low speed a few times to ensure there's no unusual noise. The whole process takes about 40 minutes, but beginners might prefer paying a professional shop for peace of mind. Remember to regularly check the brake pad thickness; replace them if they're thinner than 3mm to avoid potential hazards.
As a DIY enthusiast, changing the rear brake pads on my Envision is like a fun toy project! You'll need basic tools: wrenches, screwdrivers, and a caliper retraction tool (costs just tens of yuan online). Simple steps: Park securely, first loosen the wheel bolts, then use a jack to lift one rear wheel. After removing the tire, the brake system is exposed. Remove the caliper bolts, hang the caliper properly, and when taking out the old pads, compare them with the new ones to avoid installing them backward. Pushing the piston back is crucial—don't force it on an Envision with electronic parking brake; use the tool to turn it slowly, or the piston might seize. Then install the new pads, lubricate the caliper pins and contact points to reduce noise. After reassembly, test at low speed to check for any squeaks. I've got the hang of changing rear brakes now, but I recommend testing brake fluid pressure before changing front brakes to avoid missing potential issues. With the right tools, it's quick, easy, and endlessly enjoyable!
