Mitsubishi Lancer Rear Drum Brakes

Adjusting rear brake drums is a crucial task that ensures optimal vehicle performance and safety. As an automotive expert with years of hands-on experience, I've encountered countless scenarios where improper brake adjustments led to reduced braking efficiency and uneven brake wear. In this detailed guide, I will share insights and expertise on effectively adjusting rear brake drums, emphasizing the importance of safety and precision.

Braking performance directly influences a vehicle's safety, and the effectiveness of rear drum brakes plays a significant role. Over time, brake drums and shoes wear down, necessitating regular adjustments to maintain their functionality. One of the primary indicators that your rear drum brakes require adjustment is a spongy or low brake pedal. Additionally, if the vehicle pulls to one side during braking or makes unusual noises, it may be time to inspect and adjust the rear drums. Before beginning the adjustment process, it's essential to gather all necessary tools. A basic toolkit should include a brake drum spoon or adjustment tool, a jack, and jack stands, wheel chocks, and safety equipment like gloves and goggles. Safety cannot be overstressed when dealing with automotive repairs, so ensure the vehicle is on a stable surface and securely lifted before starting.

Begin by loosening the lug nuts on the rear wheels while the vehicle is still on the ground. Use a jack to raise one rear side of the car, ensuring it is stable on jack stands. Place chocks on the front wheels to prevent any movement. Remove the wheel to access the brake drum. At this stage, inspect the drum and shoes for signs of wear or damage. If they're excessively worn, replacement may be necessary. The next step involves adjusting the brake shoes. Locate the rubber adjustment plug on the brake backing plate and remove it. Insert the brake drum spoon or adjustment tool into the hole and engage the star wheel adjuster inside. Turn the adjuster clockwise to expand the brake shoes outward until there is slight resistance when turning the drum by hand. This resistance indicates that the shoes are close enough to the drum to provide effective stopping power but are not so tight that they cause excessive friction.adjusting rear brake drums
Once the adjustment is made, replace the rubber adjustment plug and reinstall the wheel. Tighten the lug nuts slightly and lower the vehicle back to the ground. Ensure the lug nuts are securely tightened in a crisscross pattern to ensure even pressure distribution. Repeat the same process on the other rear wheel. After adjusting both rear brake drums, test the vehicle in a safe environment. The brake pedal should feel firm, and the vehicle should stop smoothly without pulling to one side. If the brakes still do not respond correctly, the issue may be more significant and require professional attention. Regular maintenance and timely adjustments of rear brake drums not only enhance vehicle safety but also prolong the lifespan of the braking system components. Given the complexities involved in brake systems, always refer to the vehicle's service manual for specific instructions and torque specifications. In conclusion, skillfully adjusting rear brake drums involves a blend of technical knowledge and practical experience. Always prioritize safety, and when in doubt, consult or hire a professional mechanic to ensure your brake system operates at its peak performance. Implementing these practices not only reassures safety but also cultivates trust and reliability in vehicle maintenance endeavors.
