BMW 325i Brake Disc Parts Questions & Experts Answers
Q: How to replace brake discs and pads on BMW 325i?
A: If either disc requires replacement, it's essential to replace BOTH at the same time to ensure even and consistent braking. New Brake Pads should also be installed. Apply the parking brake, raise the front of the vehicle, support it on jackstands, and remove the appropriate front wheel. Inspect the disc surface for score marks and damage; light scratches are normal, but deep scoring may necessitate disc refinishing by an automotive machine shop. Ensure the disc isn't machined below its specified minimum thickness, which can be found stamped into the hub of the disc. If the disc is potentially warped, check it for runout using a dial indicator. Some professionals suggest resurfacing the discs during brake pad replacement for a smoother finish. Additionally, inspect the disc for cracks and wear. For removal, unscrew the bolts of the Brake Caliper mounting bracket, slide off the caliper assembly, and tie it to the front suspension coil spring. Mark the disc's relationship to the hub, remove the bolt securing the brake disc, and then remove the disc. For installation, ensure clean mating surfaces for the disc and hub, align marked points from removal, wipe any preservative coating from a new disc, position the caliper over the disc, and secure it. Finally, install the wheel, lower the vehicle, and depress the brake pedal a few times to ensure brake pads contact the disc. Check the brake operation before driving.
