How do the brake discs work, and how do they remove and install on BMW Z3?

Put blocks behind the car's back wheels, then put on the parking brake. When you can, turn each front wheel bolt 1/4 turn counterclockwise. Lift the car up, keep the front wheels on while you push down on the brake caliper fluid line, supporting the caliper with wire to avoid damaging the hose. Separate the brake caliper and its bracket. Detach the special bolt that needs a 6mm hex key to remove it. If the bolt is hard to loosen, use a spray lubricant to break it free, and hit it gently with an electric impact driver. Pull off the brake rotor. To free it if stuck, unscrew the bolt holding it in place about 3 turns, spray lubricant near the hub and rotor connection, put back the two wheel bolts, and hit a flat surface between them with a light blow - but don't touch the machined surface. Take out the rotor, and make sure any new rotor is not covered in protective material. Wash the hub and the brake rotor part where they touch. Spread a thin layer of anti-stick solution on them. Fasten the brake rotor with its bolt, then tighten it to 12 foot-pounds. Drive down slowly on the brake pedal until it reaches firm pressure. Start by hand-tightening the wheel bolts, slowly lower the vehicle onto the surface, and then torque each bolt into place following an X-pattern from 66 to 81 foot-pounds of force. Warm up your brakes by stopping slowly 5 times at 30 mph, letting your brakes cool down, and finishing with 5 extra stops to rub off the layers. Check the machined surface of the brake rotor for damage, replace if you find deep scars, cracks, or unevenness, or if the surface is covered in rough ridges. Look for warpage and uneven thickness in rotors; a pulsing brake pedal or steering wheel means thickness is uneven. Look at the rotors for damage while changing the other parts, because cracks and wonky shapes can make braking dangerous. Little scoring is fine, but rotors must be resurfaced or replaced when scoring or warping gets intense. Soak new rotor protection film off with the right dissolving solution before putting it in your vehicle. Measure the space between the rotor's outer edge and center hub. Keep the measurement under 0.002 inch when the rotor is separated from its job. Only coat brakes with the thinnest legal thickness when planning repairs. To inspect a brake rotor, lift the vehicle, position jacks, put lug nuts back on the tire/wheel assembly reinstalled with washers, and tighten them to 80 foot-pounds, unwrap brake pads, then look at the brake surface. With a dial indicator, measure rotor runout, keeping values under 0.004 inches; on-car brake lathe can then machine the rotor for use. Use a micrometer to measure thickness and rotor alignment. Compare the thinnest part of the rotor against the brake manufacturer's thickness requirements. If your reading is lower than the limit, change the rotor before reinstalling. Use a brake lathe to machine the rotor if its thickness differences between highest and lowest points are larger than 0.0008 inches. Replace the rotor if the lathe makes it thinner than minimum specs.

How to remove and install the brake disc on a BMW M3?

M3 brake rotors work best when positioned a specific way. The left takes an odd-numbered part number, while the right uses an even-numbered end. Start by locking the rear wheels and using the parking brake. Loosen front wheel bolts just a little, then lift the car up and remove the front wheels. Keep the brake caliper fluid hose connected during wheel removal, and hold the caliper assembly with mechanic's wire to give it support. Pull the brake caliper and bracket out, use your 6mm socket tool to take off the tight special shouldered recessed hex fastener, and apply penetrating lubricant if needed. You can free a stuck brake rotor by first loosening the hold-down bolt then spraying lubricant around the rotor's edge, using two wheel studs to gently tap the rotor off without damaging the flat part of the hub. When putting the parts back on, check and clean the rotor first. Apply anti-seizing compound to protect it, and tighten the retention bolt to 12 foot-pounds. Do the reverse to put it all together. Make sure you tighten the lug nuts in a crossing pattern, applying 66-81 foot-pounds of force to each pair. Simultaneously press down slowly on the brake pedal to set brake strength, then released it with repeated stops to get rid of buildup on the rotors. Check the rotor for surface defects, like pits and cracks, look for unevenness, and size up excessive ridges. Measure surface flatness and overall thickness, and replace if you spot any problems. A little surface wear is OK, but severe markings and bowing needs fresh finish or replacement. Before fitting new rotors, remove any protective covering from them. Then check that your hub runs straight, keeping in mind that too much run-out should be under 0.002 inch. To check your rotors right, lift the vehicle, take off the tire, fit the lug nuts back in place, then take out the brake pads. When measuring runout, use a dial indicator. You should replace rotors when the number exceeds 0.004 inches. Then check for thinness and flatness.

BMW Brake Disc

In your BMW brake system, there is an important component named brake disc. When you succeed slowing down your speed to zero, at the same time, the brake disc connects the brake pads to produce a brake torque, further leading to a deceleration. Owing to the extreme high mechanical and thermal loads, and other factors like spray water, road grime, brake disc will fail one day. The brake disc in your car will be checked during the inspection, and if your brake disc doesn't reach the standard, then it has to be replaced without negotiation. However, you can do the replacement by yourself. When you need to find a right place to buy the right part for you BMW car, we are glad to be your first choice. We, as promised, offer all BMW genuine brake disc with a beautiful price.

BMW Brake Disc Parts Questions & Experts Answers

Ventilated Brake Disc
34116864060
Q: How do the brake discs work, and how do they remove and install on BMW Z3?
A:
Put blocks behind the car's back wheels, then put on the parking brake. When you can, turn each front wheel bolt 1/4 turn counterclockwise. Lift the car up, keep the front wheels on while you push down on the brake caliper fluid line, supporting the caliper with wire to avoid damaging the hose. Separate the brake caliper and its bracket. Detach the special bolt that needs a 6mm hex key to remove it. If the bolt is hard to loosen, use a spray lubricant to break it free, and hit it gently with an electric impact driver. Pull off the brake rotor. To free it if stuck, unscrew the bolt holding it in place about 3 turns, spray lubricant near the hub and rotor connection, put back the two wheel bolts, and hit a flat surface between them with a light blow - but don't touch the machined surface. Take out the rotor, and make sure any new rotor is not covered in protective material. Wash the hub and the brake rotor part where they touch. Spread a thin layer of anti-stick solution on them. Fasten the brake rotor with its bolt, then tighten it to 12 foot-pounds. Drive down slowly on the brake pedal until it reaches firm pressure. Start by hand-tightening the wheel bolts, slowly lower the vehicle onto the surface, and then torque each bolt into place following an X-pattern from 66 to 81 foot-pounds of force. Warm up your brakes by stopping slowly 5 times at 30 mph, letting your brakes cool down, and finishing with 5 extra stops to rub off the layers. Check the machined surface of the brake rotor for damage, replace if you find deep scars, cracks, or unevenness, or if the surface is covered in rough ridges. Look for warpage and uneven thickness in rotors; a pulsing brake pedal or steering wheel means thickness is uneven. Look at the rotors for damage while changing the other parts, because cracks and wonky shapes can make braking dangerous. Little scoring is fine, but rotors must be resurfaced or replaced when scoring or warping gets intense. Soak new rotor protection film off with the right dissolving solution before putting it in your vehicle. Measure the space between the rotor's outer edge and center hub. Keep the measurement under 0.002 inch when the rotor is separated from its job. Only coat brakes with the thinnest legal thickness when planning repairs. To inspect a brake rotor, lift the vehicle, position jacks, put lug nuts back on the tire/wheel assembly reinstalled with washers, and tighten them to 80 foot-pounds, unwrap brake pads, then look at the brake surface. With a dial indicator, measure rotor runout, keeping values under 0.004 inches; on-car brake lathe can then machine the rotor for use. Use a micrometer to measure thickness and rotor alignment. Compare the thinnest part of the rotor against the brake manufacturer's thickness requirements. If your reading is lower than the limit, change the rotor before reinstalling. Use a brake lathe to machine the rotor if its thickness differences between highest and lowest points are larger than 0.0008 inches. Replace the rotor if the lathe makes it thinner than minimum specs.

Q: How to remove and install the brake disc on a BMW M3?
A:
M3 brake rotors work best when positioned a specific way. The left takes an odd-numbered part number, while the right uses an even-numbered end. Start by locking the rear wheels and using the parking brake. Loosen front wheel bolts just a little, then lift the car up and remove the front wheels. Keep the brake caliper fluid hose connected during wheel removal, and hold the caliper assembly with mechanic's wire to give it support. Pull the brake caliper and bracket out, use your 6mm socket tool to take off the tight special shouldered recessed hex fastener, and apply penetrating lubricant if needed. You can free a stuck brake rotor by first loosening the hold-down bolt then spraying lubricant around the rotor's edge, using two wheel studs to gently tap the rotor off without damaging the flat part of the hub. When putting the parts back on, check and clean the rotor first. Apply anti-seizing compound to protect it, and tighten the retention bolt to 12 foot-pounds. Do the reverse to put it all together. Make sure you tighten the lug nuts in a crossing pattern, applying 66-81 foot-pounds of force to each pair. Simultaneously press down slowly on the brake pedal to set brake strength, then released it with repeated stops to get rid of buildup on the rotors. Check the rotor for surface defects, like pits and cracks, look for unevenness, and size up excessive ridges. Measure surface flatness and overall thickness, and replace if you spot any problems. A little surface wear is OK, but severe markings and bowing needs fresh finish or replacement. Before fitting new rotors, remove any protective covering from them. Then check that your hub runs straight, keeping in mind that too much run-out should be under 0.002 inch. To check your rotors right, lift the vehicle, take off the tire, fit the lug nuts back in place, then take out the brake pads. When measuring runout, use a dial indicator. You should replace rotors when the number exceeds 0.004 inches. Then check for thinness and flatness.
