Hi guys, I just bought an 05 Legacy Wagon and would like to change the brakes myself, can you guys point me to materials that will help.
Subaru brakes are really easy, there's not much to it. once the wheel is off you can literally change brake pads by removing TWO bolts, on some older Subaru's it was only ONE. ONE...or TWO bolts. Real easy. Has to be write ups out there for something this simple...NASIOC no doubt has one, here probably does.
1. remove wheel
2. remove brake caliper slide pin bolts
3. compress piston with c-clamp (after removing cap on brake master cylinder)
4. clean and regrease the slide pins with brake caliper grease
5. clean the brake pad clips with a wire brush if yo'ure not going to replace them. just pry them out, they pop right out with a little screwdriver persuasion
6. remove and install pads
if you're replacing rotors you remove the two 17mm (or 19) brake caliper bracket bolts to remove the bracket. the rotor then comes off. if it's hard to get off - pound it off or use a M8x1.25 (i think that's the size) bolt to thread into the two holes in the rotor - keep screwing the bolt until it "pushes" the rotor off the hub. you often need 2 bolts for each rotor - one for each hole and the threads get mangled due to the forces involved and the bolts are not reusable.
new clips are nice to get and some pads (very few and they're going to be more expensive) will have new clips in them. i bought some Adaptive One pads from NAPA that had new clips with them.
the clips get dusty/corrosion build up and eventually over time that can prevent a pad from sliding properly in and out. doesn't happen often but nice to avoid too.
brake jobs are really easy - the hard part is stuck rotors and seized guide pins, tricky things like that. but just changing pads is super simple.
