5. آپريٽنگ غور ويچار
5.1. Brake System Break-In
After installing new brake drums and shoes, a proper break-in procedure is crucial for optimal performance and longevity. This process helps to seat the brake shoes to the drum surface and burn off any manufacturing residues.
- Drive the vehicle at a moderate speed (e.g., 30-40 mph).
- Apply the brakes moderately (not hard) to slow down to about 10 mph. Do not come to a complete stop.
- Repeat this process approximately 10-15 times, allowing a few minutes between each cycle for the brakes to cool.
- Avoid heavy braking or prolonged stops immediately after installation.
- After the break-in period, allow the brakes to cool completely before normal driving.
6. سار سنڀال
Regular inspection and maintenance of your brake system are essential for safety and performance.
6.1. باقاعده معائنو
- Inspect brake shoes for wear at least every 12,000 miles or annually. Replace if friction material is less than 2mm thick.
- Check brake drums for excessive wear, scoring, or cracks. Drums should be replaced if they exceed the maximum diameter stamped on the drum or show significant damage.
- Inspect wheel cylinders for leaks. Replace if any leakage is observed.
- Check brake hoses for cracks, bulges, or leaks. Replace if any damage is found.
- Ensure the parking brake operates correctly and adjusts properly.
