How to Replace the Brake Pads on a LaCrosse?
3 Answers
LaCrosse brake pad replacement method: For models with electronic parking brakes, the standard procedure requires entering the brake system maintenance mode first. Turn on the power, press the parking brake button three times consecutively while holding down the brake pedal until the parking brake mode indicator flashes on the dashboard. Then use a caliper piston retraction tool to compress and retract the piston, ensuring the two notches on the piston are vertically aligned. Install the new brake pads afterward. If the vehicle does not have an electronic parking brake, there is no need to enter the brake system maintenance mode. The LaCrosse is a new mid-to-high-end sedan introduced by SAIC-GM, with dimensions of 5005mm in length, 1858mm in width, and 1500mm in height, a wheelbase of 2837mm, and front-engine, front-wheel-drive configuration.
I've changed the brake pads on my LaCrosse several times myself, and it feels quite simple as long as you're patient. First, find a flat surface to park, engage the handbrake, and use a jack to lift one side of the car. Place wheel chocks behind the rear wheels to prevent rolling. After removing the tire, you'll see the brake caliper. Use a wrench to loosen the caliper bolts and gently remove it, hanging it aside without pulling on the brake line. Pry off the old brake pads and replace them with new ones, making sure they're oriented correctly and not installed backward. When pushing the piston back, I use a C-clamp to slowly press it in or place an old pad underneath for leverage. Reattach the caliper, tighten the bolts, put the tire back on, and lower the car. Sit inside and pump the brakes hard several times to reset the piston. The whole process shouldn't be rushed—take your time, and it should take about an hour. The tools needed are basic household items like a jack and wrenches. For safety, remember to wear gloves and goggles, and be cautious of the wheel falling off. After driving for a few days, the new pads will bed in, and the noise will disappear. It saves money and builds skills, but beginners should consider having someone accompany them.
Safety first when replacing the LaCrosse brake pads – I emphasize this because I've made mistakes before. Park the car securely and use a reliable jack with wheel chocks for double protection against slipping. After removing the wheel, detach the caliper carefully without force and avoid touching the brake hose to prevent leaks. Before installing new pads, inspect the brake discs for deep grooves – replace the discs if necessary, otherwise the pads will wear out quickly. A dedicated piston press tool is recommended to avoid damaging the system. After reassembly, test the brakes by pressing the pedal, then conduct a slow test drive. If you encounter sticking or unusual noises mid-process, don’t force it – visit a professional shop with proper tools and warranty coverage. Brake failure risks aren’t worth skimping on. DIY material costs ~¥200, but a full shop replacement runs ~¥500 – the extra expense ensures road safety. Inspect brakes every 20,000 km to preempt failures.
