Replacing Brake Discs, Callipers, and Pads

Model: Subaru Legacy MK 4, BP, BL - Years 2003-2009
Part: Brake rotors

This guide explains how to replace the discs, callipers, and pads of your car's braking system. Gather your spanners and start by loosening the bolts on the callipers, then remove everything to easily access the pads. Remove and replace the pads. After this, focus on the disc. If the disc is worn, old, and rusty, tap the sides of the disc with a hammer to create some play and remove it easily. Once this is done, degrease everything with WD-40 and clean it thoroughly. Ensure the correct orientation of the pins and replace with a new disc. After reaching this point, you can fit the calliper with the new pads, and your work will be complete. Your braking system will be as good as new.
