Mitsubishi Lancer Rear Drum Brakes

Experiencing trouble with your brake drum not going back on can be frustrating, especially if you're unsure where to start. But understanding the potential reasons behind this common automotive issue can save you both time and stress. Here's a detailed exploration from an experienced perspective, combining expertise and authority in automotive maintenance, ensuring that you can trust the guidance provided.
One of the primary reasons your brake drum may resist going back on is due to improperly adjusted brake shoes. In many cases, the brake shoes might be positioned too far out, preventing the drum from sliding back over them. To rectify this, use a brake adjustment tool to turn the star wheel adjuster until the shoes retract sufficiently, allowing the drum to fit properly. Another common issue can be the presence of rust or debris on the drum or hub. Over time, brake components collect rust, dust, and dirt, especially if the vehicle has been stationary for a while. This accumulation can hinder the reinstallation of the drum. To resolve this, thoroughly clean the hub and the mating surface of the drum using a wire brush or sandpaper. This ensures a clean, snug fit when reinstalling the drum.

In some instances, new brake hardware could lead to difficulties in installing the drum. After replacing components, such as springs or the adjuster mechanism, the new parts may initially cause alignment issues. Double-check that each component is correctly installed and seated. Ensuring that each piece is in its intended position can often resolve the struggle with fitting the drum. On other occasions, a warped brake drum might be the culprit. If the drum has undergone excessive wear or heat exposure, it can lose its round shape, leading to fitment issues. In such cases, it's advisable to measure the drum's diameter with a micrometer to confirm its specifications. If warping is detected, replacing the drum is typically necessary to ensure safety and proper function.why won't my brake drum go back on
It’s also essential to consider whether the brake shoes themselves are too thick. This is especially prevalent with new brake shoe installations, where the linings have not yet worn down. Measuring the thickness of the shoes compared to the specifications for your vehicle's make and model can help determine if this is the issue. Alternatively, allowing some driving time for initial wear might also help the drum to fit more easily over the shoes. Sometimes, the problem can stem from improper brake drum alignment when attempting to reinstall it. Ensure that when you're placing the drum back onto the hub, it's aligned correctly. If the drum is slightly tilted or mispositioned during installation, it will not sit properly. Taking the time to check that the drum is evenly aligned with the hub can often solve the problem. Lastly, always double-check that you’re using the correct drum for your vehicle. Mismatched parts are often overlooked and can easily derail your maintenance efforts. Confirming the part number and compatibility according to your vehicle’s specifications is an important step to avoid unnecessary complications. In summary, the issue of a brake drum not going back on is typically due to either misadjustment, contamination, incorrect parts, or component wear. By methodically addressing each potential cause, using both mechanical insight and precise attention to detail, you can effectively resolve this issue. Working on your vehicle’s brake system not only requires technical expertise but also a commitment to ensuring each repair and adjustment adheres to safety standards.
