How to Solve the Problem of Uneven Braking in Trucks?

Truck brake imbalance requires checking the braking force of each wheel, as well as inspecting the master brake cylinder and wheel brake cylinders, along with the brake lines. Here are some key points about truck brake imbalance: 1. Importance of Brakes: The braking system is a crucial component of a vehicle, directly related to driving safety. 2. Conditions Leading to Uneven Braking: Uneven wear between the left and right wheels can also cause uneven braking. If the left and right wheels are not equally worn, the tire grip will differ, leading to uneven braking during deceleration.
I've been driving heavy trucks for over a decade, and the issue of uneven braking is both common and dangerous, especially when the vehicle pulls to one side during downhill descents. This could be caused by a seized wheel cylinder leading to excessive braking on one side, or uneven brake pad wear creating traction differences. It's advisable to first check if the tire pressures are balanced when parked, and simply inspect for differences in brake pad thickness. If the fluid reservoir is transparent and shows uneven fluid levels, there might be a leak in the brake line or air bubbles causing blockage. Regular maintenance checks are essential, such as having a mechanic adjust the brake balance every quarter. Neglecting these issues could lead to burnt brake drums and increased risks, so it's best to visit a professional repair shop as soon as possible. Safe driving starts with attention to detail, and delaying repairs will only worsen the vehicle's condition and increase costs.
Checking truck brake imbalance yourself isn't difficult, and I often save money this way. Start the vehicle and lightly apply the brakes to listen for differences in sound between left and right - focus inspection on the side with abnormal noise. Check that tire pressures are consistent, as underinflation can affect braking balance. Lift the brake disc or drum to inspect pad thickness - replace if uneven. Differences in brake fluid reservoir levels indicate line issues, possibly requiring fluid top-up or hose replacement. If preliminary checks don't resolve it, visit a 4S shop for mechanic adjustment of the pressure balance point. These steps take some time but prevent bigger failures - safety first, don't cut corners.
Feeling the steering wheel being suddenly pulled to one side while driving is usually a sign of uneven braking. I've experienced this several times; it often happens when the caliper piston doesn't retract smoothly or there's an imbalance in fluid distribution. Focus your inspection on the sealing of the brake lines and the wear of the brake pads, and adjust the balance clearance as soon as possible. Don't delay until increased friction damages other components. It becomes even more troublesome after the brake lining burns out, so repair it promptly to ensure smooth driving control.
