What to Do If a Vehicle Fails the Brake Inspection During Annual Check?
2 Answers
Introduction to measures for failing the brake inspection during annual vehicle check: Release air from the side with less braking force, i.e., the left tire. If the testing line reports insufficient braking force, you can appropriately increase the vehicle's load (such as filling up the fuel tank, carrying a spare tire, etc.). Below are the detailed explanations: 1. The braking ratio is the ratio of brake shoe pressure to gravity, i.e., the brake shoe pressure per KN of gravity. The braking capability of locomotives and vehicles cannot be solely represented by the total brake shoe pressure; only the braking ratio can accurately indicate braking capability. 2. The braking ratio is an important parameter to measure the braking capability of locomotives and vehicles. An excessively high braking ratio can easily cause wheel skidding, while an insufficient ratio results in inadequate braking force.
The other day when I took my car for the annual inspection, it failed the brake test - which is actually quite common. I went straight to my regular repair shop. The mechanic said they'd first check the brake pad thickness and found it had worn to the limit. After replacing the new brake pads, they also adjusted the handbrake cable and cleaned the rust inside the wheel cylinders. Before the re-inspection, I deliberately tested the brakes with several hard stops to get a feel. It passed in the end. A reminder to everyone: if the brake fluid hasn't been changed for too long, it can also affect the test results. It's best to change it every two years. If you notice the brakes feeling spongy or hear unusual noises during normal driving, get them checked in advance - don't wait until the annual inspection to panic.
