Brake shoes and pads are some of the components on a BMW and other cars that need to be changed at regular intervals. Knowing when you should replace the rear brake caliper on a BMW is not the same, however. Having this knowledge is important to make sure you do not have a catastrophic breakdown on your BMW or fall into a situation that is dangerous for your family. Now, let’s discuss what you need to know on when to replace your BMW calipers.
Symptoms of a Poor Rear Brake Caliper
When to change your BMW’s rear brake caliper is one of the most important things to know on your BMW. Short of regular servicing and how important it is for a BMW owner, there are ways to recognize when your rear brake caliper is bad. We will discuss servicing in a moment, but first, here are a few reasons you can discover yourself in case it happens to your BMW.
- Vehicle Pulling During Braking: When pressing on the brake pedal, your car should come to a smooth and aligned stop, as quickly as possible, and in a safe way. If you have an issue with a brake caliper you may experience the car pulling to one side when pressing down on the brake pedal. This can be a dangerous situation if you are ready for it, but even more if it comes as a surprise during braking.
- Brake Fluid Leaks: The calipers on your BMW use hydraulics to create the braking motion. If your rear caliper is damaged or worn, you may see a fluid leak coming from the inside side of your tire and on the ground under it. Take note that the more fluid you lose in your car’s brake system, the more chances of having an accident when your car will not stop when the pedal is pressed.
- Burning Smell: As discussed a rear caliper on your BMW brake system activates the motion to stop, but it also releases the brake system when you are not in a braking motion. If your caliper is damaged, and the brake pads do not release from the braking action, you will soon smell the brake pads burning off from friction. If you smell this, stop your car and have it inspected right away by a trained BMW technician.
- Uneven Brake Pad Wear: If the rear calipers on your BMW are only partially working, you will find that the brake pads are wearing unevenly. All pads should wear the same amount. To find this, your BMW’s brake system will need to be inspected to discover the issue.
