What is the adjustment method for block brakes?

Loosen the screws on both sides; push the screws into position without tightening them. Tighten both sides inward, then release the brake to check and fix the gap.

Adjusting drum brakes is no trivial matter—it took me several attempts to get the hang of it. Before starting, ensure the car is parked on level ground with the handbrake fully engaged and the engine off—safety first. Then, jack up the vehicle, remove the wheel to expose the brake assembly, and locate the adjustment hole—usually on the side or back. Use a wrench to loosen the locknut, but avoid excessive force to prevent stripping. Next, insert a screwdriver and turn the star wheel clockwise or counterclockwise until you feel slight resistance when manually rotating the hub, indicating proper clearance (ideally 2–3mm). Tighten the nut, reinstall the wheel, lower the car, and test the brake pedal for normal travel and absence of unusual noises. Essential tools include a 10mm wrench and screwdriver—don’t cut corners. Beginners risk over-adjusting, leading to dangerous brake failure. During routine maintenance, check the wear on the brake shoes; replace them if they’re too thin to avoid emergencies. Patience is key—proper adjustment ensures responsive braking and accident prevention.
