Hey there! As a brake drum supplier, I've seen my fair share of folks scratching their heads over how to adjust brake shoes in a brake drum. It's not as complicated as it might seem at first glance, and in this blog, I'll walk you through the whole process step by step.
First things first, let's talk about why you might need to adjust your brake shoes. Over time, brake shoes wear down. When this happens, the gap between the brake shoes and the brake drum increases. This can lead to a spongy brake pedal, longer stopping distances, and overall less effective braking. Adjusting the brake shoes restores that proper gap, ensuring your brakes work as they should.
Before you start, you'll need a few tools. You'll want a brake spoon or a flat - tip screwdriver, a jack and jack stands, a wheel chock, and a pair of safety glasses. Safety is always the top priority, so make sure you're working on a flat, stable surface and that the vehicle is in park (for automatics) or in gear (for manuals).
Let's get started with the actual adjustment process. The first step is to safely lift the vehicle. Place the wheel chocks behind the wheels that won't be lifted. Then, use the jack to lift the vehicle at the appropriate lifting point. Once it's high enough, place the jack stands under the vehicle for extra support. Lower the vehicle onto the jack stands.
Now, remove the wheel. You'll need to loosen the M22 Wheel Bolt with a lug wrench before you lift the vehicle, and then fully remove them once the vehicle is on the jack stands. Carefully take off the wheel and set it aside.
Next, you'll need to access the brake drum. In some cases, there might be a dust shield or other components in the way. If so, you'll have to remove them carefully. Once you can see the brake drum, try to remove it. Sometimes, the brake drum can be stubborn. If it won't come off easily, it might be because the brake shoes are too close to the drum. You can try tapping the drum gently with a rubber mallet to loosen it.
Once the brake drum is off, you'll see the brake shoes. There's an adjuster mechanism usually located near the bottom of the brake assembly. This adjuster is what you'll use to change the position of the brake shoes.
The adjuster typically has a star - shaped gear. You'll use your brake spoon or flat - tip screwdriver to turn this gear. Turning the gear in one direction will expand the brake shoes, and turning it in the other will contract them. You want to adjust the shoes so that there's just the right amount of clearance between the shoes and the drum.
To check the clearance, you can try to rotate the brake drum by hand. It should turn smoothly but with a slight drag. If it turns too freely, the shoes are too far from the drum, and you need to expand them. If it's hard to turn, the shoes are too close, and you need to contract them. Keep making small adjustments and checking the rotation of the drum until you get it right.
While you're at it, take a good look at the brake shoes. Check for signs of excessive wear, cracks, or other damage. If the brake shoes are worn beyond the recommended limit, it's time to replace them.
Once you're satisfied with the adjustment, it's time to put everything back together. First, clean the brake drum and the brake shoes. You can use a brake cleaner to remove any dirt, grease, or debris. Then, carefully place the brake drum back on the assembly. Make sure it fits snugly.
Next, reinstall the wheel. Put the M22 Wheel Bolt back in and hand - tighten them as much as you can. Then, use the lug wrench to fully tighten the bolts in a star pattern to ensure even tightening.
Lower the vehicle off the jack stands using the jack. Remove the jack stands and the wheel chocks.
There's one more thing to check. Before you take the vehicle for a spin, pump the brake pedal a few times. This will help seat the brake shoes properly. Then, go for a short test drive in a safe area. Pay attention to how the brakes feel. The pedal should feel firm, and the vehicle should stop smoothly.
