How to Replace the Brake Discs and Pads on a BMW X1

To replace the brake discs and pads on a BMW X1, start by opening the hood. Remove the cover of the brake fluid reservoir located at the base of the windshield (left side).

Lift the front of the car on the left side, remove the front wheel, and slightly loosen the brake disc screw using a flathead screwdriver. Remove the front clip of the caliper, then disconnect the pad sensor.

Remove the rubber caps from the caliper bolts and unscrew the caliper bolts. Detach the caliper, insert a special tool into the caliper to retract the brake piston, and hang it on the suspension spring.

Once the caliper is removed, take out the pads and unscrew the bolts holding the caliper bracket to the disc, then remove the bracket as well. With the bracket off the disc, slightly unscrew the disc screw without removing it from the thread.

Tap the back of the disc to loosen it, then remove the screw and the disc. Use a wire brush on the center part of the hub, then apply some ceramic paste on both the hub and the screw hole once the new brake disc is in place.

Tighten the disc screw to the correct torque, and apply ceramic paste on the screw head as well. Now position the pad bracket and tighten the two rear bolts to the correct torque.

Apply ceramic paste on the pad clip that goes into the caliper and its support tabs on the bracket. Spread some ceramic paste on the other tabs of the other pad, position it on the bracket, reattach the caliper to the bracket, tighten the caliper bolts, replace the caps on the bolts, reconnect the pad sensor, reattach the pad clip, put the wheel back on, tighten the bolts, lower the car, tighten the bolts, and check the brake fluid level, topping off if necessary.

Repeat the same procedure on the other side.
