Needless to say, brake repairs are critical. Your brakes ensure your family’s safety. This is not to say that brake repairs and parts are not expensive. They are. Brake rotors built for import cars have minimal thickness to save weight. This means that they can’t be turned…they have to be replaced, according to Big Motoring World specialists.

Moreover, Big Motoring World Canterbury brake rotors on imports are sensitive to warping from heat, and overheated brakes are the second most common cause of failure, the first being wear and tear.

When Inspecting Your BMW Brakes, Use Your Eyes and Ears

Big Motoring World specialists recommend that you inspect the condition of your brakes visually at least half yearly. Below are some things to look for:

  • BMW Brake Rotors (disks): Their inspection should be all the way around the surface and on both sides for any concentric grooves (scoring) or noticeable defects. In case you find defects, replace your rotors immediately. Any discoloration on a rotor could be a sign of overheating and an inspection by Big Motoring WorldSnodland specialists is necessary.
  • BMW Brake Pads: They will typically match rotor scoring. However, they should also undergo inspection for uneven wear, breakage or cracking on the friction surface. Again, if you find defects, replace the brake pads immediately. BMW cars have brake pad sensors that warn of pad wear. Big Motoring World specialists recommend replacing the BMW pads and sensors at the same time.
  • BMW Brake Drums (if present): You should make sure these receive inspection on a regular basis by Big Motoring World Prestige specialists, if you happen to reside in the area. Check for the same kinds of defects noted above. The drums shouldnot have excessive grooves or have a deep “ditch” dug into them where the shoes ride.
  • BMW Brake Shoes (if equipped): They should be worn out evenly and have no rivets protruding to the friction surface.
  • Additional Troubleshooting: When checking the brakes, inspect fitting and hoses, wheel cylinders, and calipers for any hydraulic fluid leakage.

Check the reservoir, master cylinder and proportioning valve assemblies. Rebuild or replace as required. A brake pedal that has gotten lower underfoot or one that is “spongy” also requires looking into. It can be because of worn pads, sticking calipers, hydraulic system problems or low fluid.

If you are unable to “pump them up,” then you certainly have hydraulic problems that require work. In case you always have to pump them up, at the very least, your hydraulic fluid requires replacement.

To inspect by sound, know how your brakes should sound and keep an ear out for unusual noises. Most vehicles have a slight brushing sound from the pads lightly touching the rotors. This is normal. Nevertheless, beware of squeaking, rhythmic noises, and constant braking noise. As soon as you hear these, consider immediate replacement. Do not delay brake repairs as it may be dangerous.

In addition to preventing physical harm, the sooner you fix brake problems on BMW, the less costly it is.
