There are many people who enjoy working on their own vehicles. If you’re one of them and have a tendency to do your own brakes, you might run into some problems if you’ve never replaced brake drum pads.
Here are the three biggest mistakes that other BMW owners have made when replacing brake drum pads.
Mistake #1: Not paying attention to how everything goes back together.
When you remove the tire and the brake drum, you will see a series of springs, clips, pads, and more. Every car is different, even each BMW. If you don’t pay attention to how everything goes together, you could end up putting a spring back in the wrong position or not situating it behind the emergency cable properly, or something else, for example. If you don’t put everything back the way it’s designed to go, the brakes may not function properly.
Mistake #2: Assuming brake drum pads are no different than disc brakes.
While the essentials are the same, such as the pad surface, brake drum pads operate completely different from disc brakes. For brake drum pads, there is a component that expands as the pad begins to wear down. This usually results in a nut pushing down and locking in place and if it is not return to the smallest position, it can be incredibly difficult, if not impossible, to put the brake drum back on.
Mistake #3: Not paying attention to the brake pad width.
Aftermarket brake pads may not fit within the brake drum itself because they may be thicker than the original brake pads. This can make it almost impossible to get the brake drum on, and if you actually manage to do that, the wheel may not turn properly.
That’s why it’s best to bring your BMW to an authorized service center and have an experienced technician replace your brakes.
