BMW Brake System Repairs: Replacing your brake components before they show signs of failure help to avoid costly brake system repairs.
Keep your family safe. Brake rotors for BMW are built with minimal thicknesses to save weight - meaning they can't be "turned"; they must be replaced.
BMW brake rotors are sensitive to warping from heat, and overheated brakes are the second most common cause of failure (first is wear-and-tear).
Save money on BMW brake repairs by Inspecting your Brakes every 6 months.
BMW Brake Rotors (discs)
Inspected all the way around the surface and on both sides for any concentric scoring (grooves) or obvious defects.
If defects are found, replace your rotors immediately. Any rotor discoloration may be a sign of overheating and an inspection by a BMW brake repair professional is needed.
BMW Brake Pads
Inspected for uneven wear, breakage or cracking on the friction surface.
If defects are found, replace the pads immediately.
Many BMW's also have brake pad sensors to warn of pad wear. If your BMW uses sensors, replace these at the same time as your pads.
BMW Brake Drums & Shoes (if equipped)
Inspect periodically. Check for the same types of flaws as noted above. The drums should not have excessive grooves or have a deep "trough" dug into them where the shoes ride.
Should be worn evenly and have no rivets protruding to the friction surface.
BMW Brake System Checks and Sounds
When inspecting brakes, check calipers, wheel cylinders, hoses and fittings for any hydraulic fluid leakage.
Inspect the master cylinder, reservoir and proportioning valve assemblies as well. Replace or rebuild as required.
Spongy brake pedal could be caused by sticking calipers, worn pads, low fluid or hydraulic system problems. (If you can't "pump them up", then you definitely have hydraulic problems)
Check brakes by sound, know how your brakes should sound and listen for out-of-the-ordinary noises.
Squeaking may be caused by dust or dirt on the brakes, loose pads vibrating when applied or worn pads.
Rhythmic noise might mean you have a warped rotor. Instead of a solid squeaking noise, it pulsates. In extreme cases, the brake pedal will also pulsate underfoot.
Constant brake noise is never a good sound and any grinding noise spells real trouble!
As soon as any problem is noticed, get it repaired immediately. Delaying brake repairs is extremely dangerous. Brakes may be too worn or damaged to stop your BMW in an emergency. Not fixing brake system problems timely increases the cost of doing so. Badly worn, warped or overheated rotors can damage wheel bearings and the complete wheel hub assembly. Brakes should be examined by a BMW professional. Checking brakes for "run-out", warping, wheel bearing play, proper balance, are normally more involved than can be accomplished in your garage. This inspection can also uncover underlying problems that could eventually become costly or dangerous.
