Installation Notes and Tips

Ensure the brake system is fully depressurized before removing the old caliper. The L4923 caliper includes caliper slides and a mounting bracket but does not include mounting hardware, so retain or replace existing bolts as needed. Use the correct M10 x 1.5 bleeder screw for brake fluid bleeding. Verify piston movement and caliper alignment during installation to prevent uneven pad wear.
