The listing title also names the X3, Z4, 3 Series and 5 Series. It is sold as a single disc, in silver. Easy Life Markets offers it for owners and workshops who need to replace a worn or damaged disc and are able to match it against the one on the car.\u003c\/p\u003e\n\n\u003cp\u003eWe will be straightforward about this listing: the supplier gives very little technical data. There is no diameter, no thickness, no part number and no statement of whether the disc is for the front or the rear axle. BMW fits several different disc sizes across these model ranges depending on engine and brake package, so this is a part you should confirm carefully before buying. The sections below tell you exactly what is known and how to check.

Two braking faces are joined by a ring of internal vanes that draw air through the disc as it spins, which is how a vented disc gets rid of heat. The whole surface has a light grey protective coating, the kind used to stop a disc rusting in storage and on the areas the pads do not sweep. The coating on the braking faces wears off during the first few stops, which is normal.\u003c\/p\u003e\n\n\u003ch2\u003eSigns a Brake Disc Needs Replacing\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVibration through the pedal or steering wheel when braking\u003c\/li\u003e\n\u003cli\u003eA raised lip around the outer edge of the disc\u003c\/li\u003e\n\u003cli\u003eThickness at or below the minimum figure stamped on the disc\u003c\/li\u003e\n\u003cli\u003eVisible cracks, deep scoring or blue heat marks\u003c\/li\u003e\n\u003cli\u003eHeavy corrosion on the braking face that does not clean off after driving\u003c\/li\u003e\n\u003cli\u003eA brake wear warning on the dashboard when the pads have also reached their limit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReplace discs in axle pairs and fit new pads at the same time.

Avoid heavy stops and do not sit stationary with the pedal pressed hard when the brakes are hot. After washing the car, a short drive with a few light brake applications dries the discs and keeps surface rust from forming.\u003c\/p\u003e\n\n\u003ch2\u003eWho This Disc Is For\u003c\/h2\u003e\n\u003cp\u003eThis disc suits BMW owners and independent specialists who have the original part details to hand and can verify the match before fitting.
