Mitsubishi Lancer Rear Drum Brakes

Encountering the issue of a brake drum that won't fit over new shoes is not only frustrating but can also be a concern for the safety and functionality of your vehicle. As an experienced automotive expert with years in the field, I understand the intricacies this problem brings, and I'm here to share insights and practical solutions that can help you resolve it effectively.

One of the primary reasons why a brake drum won't fit over new shoes is the improper adjustment of the brake shoes themselves. When brake shoes are installed, it's crucial that they are adjusted to sit properly within the brake drum. Often, they might expand beyond the intended circumference, causing the drum to not fit over them. Ensuring correct adjustment requires understanding the working mechanism of the adjuster screw, and tweaking it so that the brake shoes retract to a position that comfortably allows the drum to slide over them. Another key factor could be the thickness or size of the new shoes. Not all brake shoes are equal, and there's always a possibility that the new ones are slightly thicker than standard, especially with aftermarket products. To address this, always verify that the new brake shoes align with the original specifications provided by the vehicle's manufacturer.

Contamination or debris on the components is also a potential cause for improper fitting. Dirt, dust, and other forms of contamination can accumulate on the new brake shoes or within the brake drum, creating irregularities that prevent proper fitting. Cleaning all components thoroughly before installation is a non-negotiable step. Utilize a quality brake cleaner and ensure that all components are dry and free from foreign particles prior to fitting them together. Warpage or damage to the brake drum might also be the culprit. Over time and with extensive use, brake drums can warp, leading to a change in their shape and size. Inspecting the surface of the drum for any signs of damage or distortion is crucial. If any warpage is detected, consulting with a professional to either properly machine the drum or replace it might be the necessary course of action.brake drum won't fit over new shoes
Using the incorrect parts can also cause fitting issues. It's imperative to double-check the parts, ensuring they are tailored for the specific make and model of your vehicle. Even a small deviation in size or design can lead to fitting problems. Working closely with a reputable parts supplier can eliminate issues arising from incompatible parts. There's also a possibility that the self-adjuster mechanisms are not functioning properly. These mechanisms are responsible for adjusting the position of the shoes as they wear down. If they malfunction, they can hold the shoes in an expanded position, thus hindering fitting. Regular inspection and, if necessary, replacement of the self-adjuster can resolve such issues. Finally, considering professional assistance should not be underestimated. If initial troubleshooting does not yield satisfactory results, seeking the expertise of a certified mechanic can provide a comprehensive solution. Professionals have the experience and tools to diagnose underlying issues that might not be apparent at first glance. Ensuring your vehicle's braking system functions effectively is vital, not just for vehicle performance but for your safety on the road. By understanding and addressing the potential issues that prevent a brake drum from fitting over new shoes, you ensure not only a smooth installation process but also peace of mind knowing that your brakes are reliable and efficient. Employing both a detailed inspection routine and consulting with certified professionals when needed are the hallmarks of responsible vehicle maintenance.
