Installation Notes and Tips

Verify brake fluid type against the vehicle’s master cylinder reservoir cap and use fresh fluid from a sealed container. Clean the mounting surfaces before installation, and inspect hoses, pads, and rotors for wear before returning the vehicle to service. Silicone grease is used on floating caliper mounting pins. For BMW rear left brake caliper replacement, confirm the bracket and port sizes match the original unit before installation.
