Why are the front brakes seizing in my GWM ute?

I have a H5 2.0 Diesel and the front brakes keep seizing. After releasing pressure by loosening the nipple on the caliper, I am able to drive 10 to 15km before they seize up again. I have taken it to the dealership twice but they can’t find the fault or reason for this. What can I do?

This is a potentially lethal fault as anything amiss with a car’s braking system is a major recipe for disaster. It sounds as though the braking system is applying pressure when you hit the brake pedal, but not allowing the pressure to release when you take your foot off the brake.

If yours was an older car, I’d be suspecting the flexible brake hoses had collapsed internally, allowing the brake fluid to pass through them one way but not return. However, this seems unlikely in a car as new as the one you’ve described. Which leads me to think that perhaps the brake master cylinder is at fault or, perhaps the anti-lock braking system is the culprit as this system controls the flow of fluid to each caliper. Either way, it’s straight back to the dealership for a warranty claim, but I’d be taking the vehicle there on the back of a truck as it really doesn’t sound safe to drive as it is. Driving a car with binding or dragging brakes can very quickly overheat the brake fluid, leading to a complete brake failure with obvious potential results.

If you’re unhappy with the service from your dealership, I would suggest contacting the manufacturer’s customer service division and stating your case. I’d also be asking for a replacement car until yours is fixed.
